MULTI-LANE HIGH-SPEED ENCRYPTION AND DECRYPTION

摘要

An encryption system is configured to include a combination of block (130) and stream (150) cipher generators. The block cipher generator (130) provides a changing key (149) that is used to periodically re-key one or more stream cipher generators (150). Preferably an AES block encryptor (135) provides a set of 128-bit ciphers (139) that are used to provide a stream of 576-bit keys (149) that is used to periodically re-key one or more SNO W-2 stream cipher generators (150). The output (159) of the stream cipher generators (150) are used to encrypt multiple input data streams (263-264), or 'lanes' of data, using an optimized arrangement of the block (130) and stream (150) ciphers relative to these multiple lanes of data (263-264).
