opportunity at finding non-random data, compression occurs before
encryption, in the order:
compression encryption // decryption decompression
Adding compression to an encrypted link increases line throughput. Once
compression has been carried out there is less data requiring encryption,
passing back to the base system, and transferring across the network, so less
base system bus and network link bandwidth is required for a given amount of
data. This results in the dual operation being very effective where encryption is
required.
