Abstract
A system and method for encrypting blocks of plain text. Output FIFO memories are provided for decoupling pseudorandom vector generation from plain text encryption. The output FIFOs produce the effect of multiplexing several cryptographic devices together and can be combined with feedback FIFO memories in order to provide key agility and parallel secret key encryption. Throughput is also enhanced by constructing wide codebooks so that a block of data can be enciphered as a whole.
