CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. non-provisional patent application, Ser. No. 14/138,653, filed on Dec. 23, 2013, which claims the benefit of U.S. provisional application No. 61/747,336, filed on Dec. 30, 2012, which are incorporated herein by reference, in their entirety, for all purposes.

FIELD OF THE INVENTION

The present invention relates generally to the field of data encryption and more specifically to the use of randomly generated keys, randomly selected encryption patterns, and, optionally, additional metadata.

BACKGROUND

In a wide variety of applications, there is the need to securely encrypt information that must remain secret. Widely used encryption algorithms such as data encryption standard (DES) and advanced encryption standard (AES) share the weakness of consistently encrypting equivalent messages the same way, over and over again. That approach exposes a potential exploitable breach of security for sensitive information, whereas an identifier, such as a Social Security Number, appear identically encrypted by prior art methods each time it occurs, creating an identifiable encrypted pattern, and is vulnerable to brute-force attacks. In accordance with Moore's Law, average computing power doubles every 18 months; and with stronger and faster computers, items vulnerable to brute-force attacks become even more vulnerable over time. Opportunities exist, therefore, to improve the security of encryption algorithms.

SUMMARY

Embodiments of the present invention utilize pointers to indicate the locations and sizes of encryption components, utilizing randomly determined patterns to be used for a random number of characters of text data being encrypted. For each randomly determined block of text, a randomly determined pattern is selected, which specifies how to combine the encryption components, including the shuffled and encrypted text, and references to that block's seed key, the size and composition of which are randomly determined. Additionally, by including a package of metadata in the encryption and decryption process, additional functionality may be added, including requiring that user defined conditions must be met to enable decryption.

In embodiments of the present invention, there is provided a methodology and system for encrypting and decrypting data, with decryption contingent upon user defined conditions being met. The encryption process comprises a method for using pointers to indicate the locations and sizes of encryption components, utilizing randomly determined patterns to be used for a random number of characters of text data being encrypted. For each randomly determined block of text, a randomly determined pattern is selected, which specifies how to combine the encryption components, including the shuffled and encrypted text, and references to that block's seed key, the size and composition of which are randomly determined.

In embodiments, the decryption of data comprises methods for reversing the process to decode encrypted text, iteratively extracting the decryption components in accordance with the pattern indicator identified for each block of encrypted text, as determined by the end block and back pointers. To enable output, a checksum of the decrypted message is matched against the checksum within the encrypted message to verify message integrity. Additionally, by including a package of metadata in the encryption and decryption process, additional functionality may be added which includes requiring user-defined conditions that must be met to enable decryption. This metadata can include any combination of constraints, including, but not limited to, a shared secret password, timestamp dependencies, location dependencies, entity or device authorization, or other user-defined parameters.

DETAILED DESCRIPTION

FIG. 1 shows a block diagram 100 of a data structure in accordance with embodiments of the present invention. Using a computer-implemented method, a plaintext 102 is converted into an encrypted data structure 103. Encrypted data structure 103 comprises a plurality of encrypted blocks, indicated as 104A and 104B. Each encrypted block comprises an end pointer 106. The end pointer 106 points to a forward location within the data structure, which is the location of a pattern indicator pointer 108. The pattern indicator pointer 108 points to a backward location within the data structure, which is the location of a pattern indicator 112. In embodiments, the pattern indicator may be randomly generated, and may include an integer based on a randomly generated key, referred to as a random seed key. The random seed key is different each time a random seed key is retrieved from the computer system used for encryption (e.g. via the operating system or other suitable source). The pattern indicator 112 may represent a selection of one of many encryption patterns. The pattern indicator 112 specifies the encryption pattern to be used for a particular block of encrypted text. The pattern indicated by pattern indicator 112 may include, but is not limited to, a randomly determined key 113, a key cluster size, a forward or backward indicator to a key cluster, and other transformational pattern data. Since the pattern indicator 112 is based on randomness, the layout of components changes with each block. Since the encryption key is based on randomness, the size and composition of encryption key 113 changes with each block. A randomly determined encryption key 113 is used for creating encrypted chunk 114, which represents a portion of encrypted information (a portion of the plaintext 102 that gets encrypted). In embodiments, the key 113 may include a symbol table reversal. In embodiments, the key 113 may represent a shuffle transform followed by a key cluster application (key cluster application illustrated in FIG. 8). The key 113 is randomly generated, and changes with each block. Therefore, the encrypted output is different in each instance of the encryption, even if the plaintext does not change. For example, encrypting the name “JOHN SMITH” will yield a different encrypted output each time. This helps thwart malicious activity based on pattern recognition. Random selection determines a substitution symbol array used for encrypting a portion of the plaintext 102. The substitution symbol array is then used to create encrypted chunk 114, which is an encrypted version of a portion of plaintext 102. The encrypted chunk size and pattern indicator preferably vary amongst the various encrypted blocks. Therefore, preferably encrypted block 104A has a different pattern indicator value from the pattern indicator for encrypted block 104B, and the size of encrypted chunk for encrypted block 104A is preferably different from the size of the encrypted chunk for encrypted block 104B. A checksum 116 of all the data included in the encrypted chunks is concatenated to the entire data structure. The checksum 116 is used during the decryption process to ensure no tampering of the encrypted data occurred.

FIG. 2 shows a block diagram 200 of an extended encrypted data structure 203 in accordance with embodiments of the present invention. While two encrypted blocks are shown in FIG. 1, in practice, many encrypted blocks may be used to encrypt plaintext 102. The data structure format includes the checksum 116, and a plurality of encrypted blocks, indicated as 204A, 204B, and 204N. In practice, there may be many encrypted blocks (e.g. thousands of encrypted blocks), and the pattern indicator, key, and encrypted chunk size may vary amongst the encrypted blocks.

In embodiments, optionally, a preamble 213 may be incorporated, which comprises encrypted metadata. The preamble 213 may have a predefined signature used to identify it. The preamble 213 may contain one or more conditional decrypt criteria. The conditional decrypt criteria may be inserted into the preamble, and the preamble may be prepended to the body of the encrypted message. The conditional decrypt criteria must be met in order to allow the data to be decrypted. Examples of conditional decrypt criteria include, but are not limited to, a time-before condition, a time-after condition, a GPS in radius condition, a GPS out-radius condition, and a GPS jurisdictional boundary condition. In addition, a GPS defined polygon may be defined, wherein decryption is allowed (or prohibited) within the confines of the GPS defined polygon. A time before condition only allows decryption if the date/time is before a certain date/time. In effect, a time-before condition defines an expiry of the encrypted data, after which time, it can no longer be decrypted. A time-after condition only allows decryption if the date/time is after a certain date/time. A GPS in-radius condition only allows decryption if the computational device is located within a certain radius from a geographical location. Conversely, a GPS out-radius condition only allows decryption if the computational device is located outside a certain radius from a geographical location. A GPS out-radius condition can be used to exclude decryption in certain locations (e.g. a competitor's headquarters). A GPS jurisdictional boundary condition only allows decryption within a given jurisdictional boundary (e.g. within the United States, or within New York). Embodiments that support a positional criterion utilize a computing platform that has location capabilities, such as a mobile phone with an integrated Global Positioning System (GPS). Some embodiments may utilize multiple conditional decrypt data. The multiple conditional decrypt data may include any user-defined criteria, including positional criterion and temporal criterion. Some embodiments may include multiple positional criteria and temporal criteria. For example, data may be encrypted having a time-before condition, a time-after condition, and a GPS in-radius condition. In this case, the data can only be decrypted at a time in between the time-after date/time and the time-before date/time, and within a predetermined radius of a geographical location. For example, a preamble formatted as:

• <HEADER>TA 11/16/2013-4:00UTC; TB 11/18/2013-4:00UTC;GPSI 1.5 N42 .651732W73 .754418
  indicates that the data is only to be decrypted between the dates of 11/16/2013 and 11/18/2013, and within a 1.5 mile radius of the geographical location represented by N42.651732 W73.754418. In embodiments, the preamble is encrypted with the substitution symbol array so that it cannot be easily discovered through reverse engineering or hacking attempts. The <HEADER> may contain a predefined data pattern to indicate the presence of the preamble, as well as other pertinent data for parsing, such as preamble size, and a number of conditional decryption criteria. However, with the preamble also encrypted, the header information is not recognizable to a hacker.

FIG. 3 is a flowchart 400 showing process steps for generating a root shuffled symbol table in accordance with embodiments of the present invention. The root shuffle symbol table represents the substitution table base. Process step 452 indicates retrieving an ordered symbol table. In process step 454, a shuffle transform is performed on the ordered symbol table, and the resulting output is shuffled symbol table 456. In process step 458, a shared secret is applied to generate root shuffled symbol table 460. The shared secret may include a user defined password. In embodiments, the shared secret of a user-defined password may be concatenated with an entity specific identifier, and/or other user-defined criteria, thereby forming an extended password. The extended password contains a user-defined portion and a hidden portion that is not exposed to a user.

FIG. 4 is a flowchart 500 showing process steps for generating an optional preamble, including conditional decrypt criteria in accordance with embodiments of the present invention. In process step 552 a password is retrieved. The encryption and decryption is symmetric, so the same password is used for encryption and decryption. In process step 554, optionally, metadata is applied to the password to form an extended password 556. The application of metadata may include appending a unique string to the password. In embodiments, the application of metadata includes retrieving an origination identifier and appending the origination identifier to the password. The origination identifier is an entity specific identifier, and may be a unique string assigned to a particular corporate entity. Computers belonging to the corporate entity are loaded with the origination identifier in an obscured location within the computer (such as in the registry or other obscure location). The origination identifier becomes part of the data used to encrypt the plaintext. Hence attempts to decrypt the encrypted data on a computer outside of the corporate entity fail because the origination identifier is not present. In this way, companies can encrypt data in such a way that it can only be decrypted on company-issued computing equipment. In process step 558, optionally, conditional decrypt criteria are encrypted using the root shuffled symbol table, forming preamble 560. The preamble may be located before the body of the encrypted message (see 213 of FIG. 2).

FIG. 5 is a flowchart 600 showing process steps for data encryption in accordance with embodiments of the present invention. In process step 652, the plaintext to be encrypted is retrieved. In process step 654, a random seed key is generated (see 902 of FIG. 8). In process step 656, the encryption parameters for an encryption block are generated. These encryption parameters include the pattern indicator, and values for the end pointer and pattern indicator pointer for the encryption block. The encryption parameters may be taken from random values. In process step 658, an encrypted chunk is created from a portion of the plaintext retrieved in process step 652. The encrypted chunk is encrypted by using a substitution symbol table derived from the encryption parameters generated in process step 656. In process step 660, a check is made to see if any plaintext is remaining. If yes, the process steps of 652, 654, 656, 658, and 660 repeat, until the condition at 660 is no, at which point the process proceeds to computing a checksum on the encrypted data in process step 662. Optionally, the file is saved in process step 664. However, some embodiments may not save the file. In some embodiments, the data may be transmitted to another entity (e.g. another computer via a communications network) without saving a permanent copy of the encrypted file. In some embodiments, the data is saved, and also transmitted to another entity.

FIG. 6 is an exemplary data flow 700 for performing a shuffle transform in accordance with embodiments of the present invention. Block 730 shows an ordered symbol table. Note that while the ordered symbol table in block 730 is a capitalized roman alphabet, embodiments of the present invention may utilize many more symbols, including the ASCII, extended ASCII, and/or Unicode symbols. The default shuffle transform utilizes a split point 732 located in the midpoint of the symbol table. Other split points are possible. The ordered symbol table is split into a first portion 734 and a second portion 736. In the next step, the first portion 734 remains the same, as indicated in block 738, and the second portion is reversed as shown in block 740. In the next step the first block and second block are interleaved, starting with the first character of the second block, resulting in shuffled array 742. Hence going from the ordered symbol table 730 to the shuffled symbol array 742 requires one shuffle transformation, denoted as ST(1). Performing a shuffle transform on array 742 (by repeating the aforementioned steps) results in shuffled block 744. Hence, shuffled block 744 requires two shuffle transforms, and is derived by ST(2), meaning shuffle the ordered symbol table twice. In general, a shuffled block can be derived by performing a transform of ST(x) on the ordered symbol table, where x is the number of times to shuffle. Hence, if the value of x is known, the appropriate number of transforms can be performed to derive a desired shuffled array.

FIG. 7 is an exemplary data flow 800 for application of a password in accordance with embodiments of the present invention. To encrypt data, a user selects a password 802. In some embodiments minimum password length and password strength test(s) may be applied to ensure a sufficiently strong password. In this example, the password is “CAT.” The password 804 is used to change a shuffled array to form the root shuffled symbol table. In this example, the process starts with shuffled array 806, which is derived by performing multiple shuffle transforms on an ordered symbol table. Then, each character in the password is used to manipulate the shuffled array 806 to form a new shuffled array. For each character in the password, the position of that character in the shuffled array 806 is identified, and a split point 808 is marked after that character. The shuffled array 806 is split into a first portion 810 and a second portion 812. The first portion 810 is shuffled to generate array 814. The second portion 812 is shuffled to generate array 816. Array 814 and array 816 are concatenated together to form new array 818, and that array is shuffled again to produce array 820. The aforementioned steps now repeat using the next character in the password (“A” in this example). The process continues until all the characters in the password are processed, and the resulting shuffled array is the root shuffled symbol table.

In the case of additional metadata the additional metadata may be concatenated to the password prior to performing the above mentioned steps, to form an extended password (see step 556 in FIG.4). If an origination identifier is in use, the origination identifier is appended to the user-provided password. For example, if the origination identifier is NHYTG, and the user provides a password of CAT, then the extended password becomes CATNHYGT, and that string is used to generate the root shuffled symbol table. When the data is decrypted, the user provides the password of CAT. The origination identifier, which is present on the device performing the decryption, is again appended to the password by the decrypting computing device, to form the extended password CATNHYGT. If the origination identifier of the decrypting device is different or unavailable, then the decryption cannot take place.

FIG. 8 is an exemplary data flow 900 for application of a key cluster in accordance with embodiments of the present invention. A key cluster provides a novel way to make many possible shuffled arrays without needing to perform additional shuffle transforms. Key cluster 902 comprises an array of numbers. The size of the array can vary. In the example shown, the size is four, and the numbers are 21, 22, 16, and 8. To perform a key cluster operation on shuffled array 904, the subset of characters identified by the position of the numbers in the key cluster are extracted (removed from their original positions) from the shuffled array 904, and may be concatenated to the front (beginning) of the original array to form shuffled array 906. This is a front key cluster. In alternative embodiments, a back key cluster is used, where the characters are concatenated to the back (end) of the original array to form shuffled array 908. The key cluster may be stored in the encrypted data structure as part of the pattern indicator 112 of FIG. 1.

FIG. 9 is a flowchart 1000 showing process steps for data decryption in accordance with embodiments of the present invention. In process step 1052, encrypted data is retrieved. In process step 1054, a shared secret password is retrieved. This may include receiving a password from a user. In process step 1056, a preamble, if present, is processed. The preamble may include one or more conditions that need to be true in order for the decryption process to proceed. These include, but are not limited to, temporal criteria, and positional criteria. Other environmental criteria may also be applied. Other decryption criteria are possible and within the scope of embodiments of the present invention. In process step 1058, a check is made to determine if the preamble conditions (decryption criteria) are satisfied. If the decryption criteria are not satisfied, the decryption process aborts in process step 1060. If the preamble is satisfied, a root shuffled symbol table (see 460 of FIG. 3) is generated in process step 1062 by appending the satisfied conditions of the preamble conditions to the password, to form an extended password (see 556 of FIG. 4). This is used as the root shuffled symbol table, the basis needed to decrypt an encrypted block in process step 1064. The decryption process of block 1064 includes finding the key, end pointer and pattern indicator pointer, and finding the pattern indicator from that. Then the needed substitution array for that block is derived by extracting the key cluster, using that key to recreate an ordered symbol table, and reversing the shuffle transformation. In process step 1066, a check is made to see if additional blocks are present. If yes, the flow returns to process step 1064 to decrypt the next encrypted block. If no, the flow continues to process step 1068 where a checksum of the decrypted data is performed. In process step 1070, the checksum derived in process step 1068 is compared with the checksum 116 (FIG. 1) from the encrypted data. If the checksums do not match, the decryption process aborts in step 1060. If the checksums do match, the plaintext is produced in process step 1072. In embodiments, the plaintext may be saved in a file.

FIG. 10 is an exemplary system 1100 in accordance with embodiments of the present invention. System 1100 may be a computer comprising memory 1120, and a processor 1122 which is coupled to (configured to read and write) memory 1120. The memory 1120 is a computer-readable medium, such as flash, ROM, non volatile static ram, or the like. In some embodiments, the memory may be non transitory. The memory 1120 contains instructions (code) that, when executed by processor 1122, performs encryption and/or decryption of data in accordance with embodiments of the present invention. System 1100 may also comprise a display 1124 and a user interface 1126 for interacting with the system 1100. The user interface 1126 may comprise a keyboard, touch screen, mouse, or the like, or any other user interface now known, or developed in the future. System 1100 may be in the form of a computer, such as a desktop or laptop computer, a tablet computer, a mobile device, or any other suitable device. In some embodiments, one or more of the following may also be present: network interface 1128, which may include wired interfaces such as Ethernet and/or wireless interfaces, such as cellular and/or WiFi interfaces; a positional system 1130, such as a Global Positioning System (GPS) receiver or other positional system; a camera 1132, and a microphone 1134. In its basic form, embodiments of the present invention provide a platform independent way to achieve efficient encryption and decryption of data, where the encrypted data is different every time it is generated, even if the plaintext does not change. In some embodiments, various hardware components, such as positional system 1130 may be required to enable the decryption of the data.

FIG. 11 is an exemplary data flow 1200 for encryption of plaintext in accordance with embodiments of the present invention. A plaintext 1240 is processed by breaking the string into portions 1242 and 1244. Then, substitution is performed, replacing characters of the ordered symbol table 1246 with a shuffled array 1248 which serves as a substitution table for text block 1242, and using a different shuffled array 1250 to serve as a substitution table for text block 1244, resulting in encrypted text 1252. For each position of the ordered symbol table, the corresponding character of the shuffled array 1248 is used. Hence, when transcribing the 1242 portion, “Y” in plaintext becomes “H” in encrypted text, and “L” in plaintext becomes “T” in encrypted text. However, when transcribing the 1244 portion, “Y” in plaintext is now represented by “N”. Since the shuffled array used to encrypt the block changes with each block, pattern analysis of the encrypted text becomes difficult. The example shown in FIG. 11 is very simple, showing two different shuffled arrays, and is for illustrative purposes only. In practice, the plaintext may be divided into hundreds or thousands of chunks, each chunk having its own shuffled array.

FIG. 12 shows examples of a plaintext 1350 and resulting encrypted output from embodiments of the present invention. Three different encrypted outputs are shown (1352, 1354, and 1356). Each encrypted output is drastically different from the other encrypted outputs. Hence, even when encrypting the same plaintext 1350, drastically different encrypted outputs are generated. In this example, the plaintext “Lt. Col McGreary: 1^st Battalion” is encrypted on three different instances, resulting in the different encrypted outputs 1352, 1354, and 1356. In this embodiment, the ordered symbol table comprises extended ASCII characters, allowing for more substitution possibilities.

Although the invention has been shown and described with respect to a certain preferred embodiment or embodiments, certain equivalent alterations and modifications will occur to others skilled in the art upon the reading and understanding of this specification and the annexed drawings. In particular regard to the various functions performed by the above described components (assemblies, devices, circuits, etc.) the terms (including a reference to a “means”) used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the specified function of the described component (i.e., that is functionally equivalent), even though not structurally equivalent to the disclosed structure which performs the function in the herein illustrated exemplary embodiments of the invention. In addition, while a particular feature of the invention may have been disclosed with respect to only one of several embodiments, such feature may be combined with one or more features of the other embodiments as may be desired and advantageous for any given or particular application.
