Delay characteristics of statistical cipher feedback mode
Howard M. Heys · 2002
We investigate the delay characteristics of a mode of operation of block ciphers, referred to as statistical cipher feedback (SCFB) mode. We conclude that SCFB can be operated at rates close to maximum efficiency with modest buffer requirements and delays. We also examine the characteristics of the cipher mode for the new Advanced Encryption Standard based on 128-bit blocks and comment on the security of the SCFB mode of operation.
