Encryption Engine

In the past, traditional encryption engines utilized a mode of encryption that was vulnerable to certain attacks and not capable of running at full capacity. Sandia has created an invention that provides a solution to the problem of keeping an encryption engine pipeline full so that the encryption engine can run at full capacity in CBC mode or other encryption modes that require feedback from previous computation.
Patent Abstract: 
Cipher Block Chaining, CBC, is the preferred mode in practice because CBC mode encryption requires feedback from the previous computation. Previous concern with the CBC mode was that the pipeline has the possibility of being flushed or run dry, however this invention allows the encryption engine pipeline to be kept full, allowing full-rate operation.
Engine pipeline kept full, allowing full-rate operation - Modes of encryption able to run at full capacity - Advanced computing - Greater efficiency
