An encryption processing system implements an encryption algorithm using a memory system comprising a multiple-port memory by performing at least one set of parallel read and write operations to the memory. The algorithm is, for example, the conventional ARCFOUR (or RC4) algorithm, and the key and state...http://www.google.de/patents/US20020186839?utm_source=gb-gplus-sharePatent US20020186839 - Apparatus and method for cipher processing system using multiple port memory and parallel read/write operations
