Title: Enhancement of utilization of encryption engine

Abstract

A method of enhancing throughput of a pipelined encryption/decryption engine for an encryption/decryption process has a predetermined number of stages and provides feedback around the stages (and of such an encryption/decryption engine) by receiving a source datablock for a given stage and encryption/decryption context identifier; indexing according to the encryption/decryption context identifier into a bank of initial variables to retrieve an initial variable for the source datablock; and generating an output datablock from the source datablock and its corresponding initial variable.

Methods for communicating data utilizing sessionless dynamic encryption

Patent Choi, Sung Nam

The present disclosure is directed to methods that provide a secure communication protocol by utilizing one step process of authenticating and encrypting data without having to exchange symmetric keys or needing to renew or re-issue digital identities fundamental to asymmetric encryption methodology.

Communication device for implementing selective encryption in a software defined network

Patent Smith, Rhett; Grussling, Barry Jakob

The present disclosure pertains to systems and methods for selectively encrypting data flows within a software defined network (SDN). In one embodiment, a communication device may be configured to receive a plurality of unencrypted data packets. The communication device may receive from an SDN controller a criterion used to identify at least one of the unencrypted data flows to be encrypted. Based on the criterion, an encryption subsystem may generate an encrypted data flow the unencrypted data packets based on an encryption key. In some embodiments, the encryption system may parse the packets and encrypt the data payloads without encryptingmore » « less

System for processing an encrypted instruction stream in hardware

Patent Griswold, Richard L.; Nickless, William K.; Conrad, Ryan C.

A system and method of processing an encrypted instruction stream in hardware is disclosed. Main memory stores the encrypted instruction stream and unencrypted data. A central processing unit (CPU) is operatively coupled to the main memory. A decryptor is operatively coupled to the main memory and located within the CPU. The decryptor decrypts the encrypted instruction stream upon receipt of an instruction fetch signal from a CPU core. Unencrypted data is passed through to the CPU core without decryption upon receipt of a data fetch signal.

Polarization-based coding/encryption using organic charge-transfer materials

Patent Kaehr, Bryan James; Reczek, Joseph J.; Winkle, Madeline Van; ...

A charge-transfer material enables patterning approach where the polarization angle in stand-alone films can be precisely defined at the single pixel level and reconfigured following initial alignment. This capability enables new routes for non-binary information storage, retrieval, and intrinsic encryption, and it suggests future technologies such as photonic chips that can be reconfigured using non-contact patterning.

Fast and secure encryption-decryption method based on chaotic dynamics

Patent Protopopescu, Vladimir A [Knoxville, TN]; Santoro, Robert T [Oak Ridge, TN]; Tolliver, Johnny S [Knoxville, TN]

A method and system for the secure encryption of information. The method comprises the steps of dividing a message of length L into its character components; generating m chaotic iterates from m independent chaotic maps; producing an "initial" value based upon the m chaotic iterates; transforming the "initial" value to create a pseudo-random integer; repeating the steps of generating, producing and transforming until a pseudo-random integer sequence of length L is created; and encrypting the message as ciphertext based upon the pseudo random integer sequence. A system for accomplishing the invention is also provided.
