摘要

The integrated processor coding chops digital word streams into predetermined sizes and generates key codes (Cb) generated pseudo randomly (10). The codes operate from a key function (K) and vector initialisation (IV) which changes for each block. The digital word blocks and key codes are combined continuously and memorised in a memory (23).
