Abstract: A computerized method supporting SSL-based or TLS-based communications with multiple cryptographically protected transmissions is described. Responsive to a first transmission including a first content encrypted with a public key of an intended recipient and a first digital signature for use in detect tampering to the first content, a second transmission is received. The second transmission includes a combined result including the first content and a second content, which is encrypted with a public key of the sender. Recovery of the first content verifies to the sender that the second transmission originated from the intended recipient. Thereafter, a third transmission is sent. The third transmission has data including at least the second content, being the remaining data after extraction of the first content from the combined result, which is encrypted with the public key of the intended recipient and a third digital signature for use in verifying non-tampering of the data.

Abstract: Embodiments of an automatic key delivery system and methods of use are described. One computerized method utilizing an automatic key delivery system includes operations of establishing, by a first network device, a communication session with a second network device, transmitting first content to the second network device during the communication session, wherein the first content is encrypted with a first encryption format, and transmitting second content to the second network device during the communication session, wherein the second content is encrypted with a second encryption format. The computerized method may further includes operations of receiving, from the second network device, third content during the communication session, wherein the third content is encrypted with the first encryption format, and decrypting the third content using a first cryptographic key corresponding to the first encryption format.

Abstract: A method for encrypting plaintext data is enclosed that includes operations of receiving the plaintext data, the plaintext data including a plurality of data portions, encrypting each of the plurality of data portions using a specific key for each data portion, merging each of the plurality of data portions together to form a single data stream, generating a data map of the single data stream, appending the data map to the single data stream, and performing a master cipher to form an encrypted distributable stream. Operations of the encrypting include: an additive operation on each byte of the first data portion using the additive table, an XOR operation on each byte of the first data portion as modified by the additive operation, a substitution operation on each byte of the first data portion using the substitution table as modified by the XOR operation.

Abstract: A system and method for generating a cryptographic key using a sequence of data segments selected by a user from one or more data resources. Raw data from the one or more data resources corresponding to each of the selected data segments, and the sequence in which such data segments are selected, is extracted and processed to generate a key. The key can be used for any cryptographic and authentication purpose. By enabling a user to select the sequence of data segments from the one or more data resources in any manner the user desires, the user can create a strong key, but also easily remember the underlying data resource and chosen sequence. This technique provides enhanced security while maintaining ease of creation and use of such security.

Abstract: An embodiment of an automatic key delivery system is described, An automatic key delivery system comprises the following operations. Herein, a first token is generated and provided to a first network device. Thereafter, a first key value pair, including the first token and a first key segment of a cryptographic key, is received by a first relay server and a second key value pair, including the first token and a second key segment of the cryptographic key, is received from a second relay server. In response, a second token to be provided to the first relay server and the second relay server. Thereafter, the first and second key segment are returned from the first and second relay servers based on usage of the second token as a lookup in order to recover the cryptographic key for decryption of an encrypted content from the first network device.

Abstract: A data transfer device including an enclosure with a plurality of input/output connection ports, a processor, a memory including a data store, and a data transfer component. The data transfer component directs the processor to transfer data from an external data source via at least one of the plurality of input/output connection ports, encrypt the transferred data, store the encrypted data on the data store, responsive to a successful transfer of the encrypted data to the data store, delete the data from the external data source, establish a connection to an external data storage service, responsive to a successful connection to the external data storage service, transfer the encrypted stored data to the external data storage service, responsive to a successful transfer of the encrypted stored data to the external data storage service, deleting the encrypted stored data from the data store.
