ABSTRACT:
A first bit of the communication signal is encrypted and forwarded to a CRC where it is processed in parallel with the encryption of the second bit. The first bit is then passed to the scrambler and the second bit is passed to the CRC where they are processed in parallel with a third bit which is encrypted. This process continues until the last bit is scrambled.
