Abstract: A cryptographic key split combiner, which includes a number of key split generators (42, 48, and 56) for generating cryptographic key splits (32, 34, 36, 38, and 64) and a key split randomizer for randomizing the cryptographic key splits to produce a cryptographic key (62), and a process for forming cryptographic keys. Each of the key split generators (42, 48 and 56) generates key splits (32, 34, 36, 38, and 64) from seed data (40, 44, 46, 50, 52, 54, 58, and 60). The key split generators may include a random split generator (42) for generating a random key split (32) based on reference data (40) and encryption date/time (44).

Abstract: A method of providing cryptographic information and flow control includes first determining a target domain from an IP address. An organization policy is looked up from a credential store, and an algorithm and credentials specified for the target domain are looked up in a domain-credential map. Any further credentials that are provided and that are permitted by the organizational policy are added. A working key is then generated, and information is received in the form of a receive packet. Any packet header is stripped from the receive packet and the remaining data is encrypted. Key splits are retrieved from the credential store, and are combined to form a key-encrypting key. The working key is the encrypted with the key-encrypting key, and a CKM header is encrypted. The encrypted CKM header is concatenated to the beginning of the encrypted data to form transmit data, and the packet header and the transmit data are concatenated to form a transmit packet.

Abstract: A cryptographic key split combiner includes a number of key split generators for generating cryptographic key splits from seed data, and a key split randomizer for randomizing the key splits to produce a cryptographic key. The key split generators can include a random split generator for generating random key splits, a token split generator for generating token key splits based on label data, a console split generator for generating console key splits based on maintenance data, a biometric split generator for generating biometric key splits based on biometric data, and a location split generator for generating location key splits based on location data. Label data can be read from storage, and can include user authorization data. A process for forming cryptographic keys includes randomizing or otherwise binding the splits to form the key.

Abstract: A system provides cryptographic processing of input data on a parallel processor array that includes plural processors. A format filter extracts control and main data from the input data. A control unit receives the control data, and based on the control data, forwards control and cryptographic parameters to the processors. A first distributor distributes to each processor at least a portion of the main data. A second distributor receives output information from each processor, and based thereon, generates output data. Each processor generates output information based on the control and cryptographic parameters. The output data is a cryptographic processing result.

Abstract: A method of securing an object at an access level includes selecting a profile for a user, including a credential having an encrypted credential public key, an encrypted credential public key encryption key, and a multiple-level access identifier. A working key is generated by binding a domain value with a random value. The object is encrypted with the working key. A random value encryption key is generated based on the shared value by decrypting the credential public key encryption key with the profile key encryption key, decrypting the credential public key with the credential public key encryption key, generating an ephemeral key pair, and generating a shared value based on the ephemeral private key and the credential public key. The random value is encrypted with the random value encryption key, and the encrypted object, the ephemeral public key, and the encrypted random value are provided for an authorized recipient.

Abstract: A method of authenticating the identity of a user to determine access to a system includes providing a plurality of factor-based data instances corresponding to a user, evaluating the factor-based data instances to determine if the user's identity is authenticated, and granting or restricting the user's access to the system if the user's identity is authenticated. More particularly, the method includes providing a modified data instance based on a second data instance, generating a key based on a first data instance, applying the key to the a modified data instance to generate a recovered data instance, interrogating the recovered data instance against the second data instance to generate an authentication value as a result of a correspondence evaluation, and granting or restricting the user's access to the system based at least in part on the validity of the authentication value.

Abstract: A secure accounting and operational method, whereby process elements are provided to a process, selected process elements are manipulated, a scheduled condition of the process is sampled at a predetermined point in the process, and the process sample is encrypted to provide an encrypted output. As a result, an authorized recipient has a high level of confidence in the reliability of the scheduled condition samples due to the integrity provided by the encryption process.

Abstract: A system for increasing the security of a computer system, while giving an individual user a large amount of flexibility and power. To give users the most power and flexibility, a standard object that has the capability to embed objects is used. To allow users even more flexibility, a standard object tracking mechanism is used that allows users to distribute multiple encrypted embedded objects to other individuals in a single encrypted object. By effecting compartmentalization of every object by label attributes and algorithm attributes, multi-level multimedia security is achieved.

To give users the most power and flexibility, a standard object that has the capability to embed objects is used. To allow users even more flexibility, a standard object tracking mechanism is used that allows users to distribute to other individuals multiple encrypted objects embedded in a single encrypted object. By effecting compartmentalization of every object by label attributes and algorithm attributes, multi-level multimedia security is achieved. Label attributes are used to restrict access to objects based on location, group, or other criteria and may specify personal access. Access type, such as read-only, write-only, and print-only may be specified. Nested embedded objects may be accessed directly through selection from a header array.
