Abstract

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.

统计密码反馈模式的延迟特性

我们研究了分组密码的一种操作模式的延迟特性，称为统计密码反馈(SCFB)模式。我们得出的结论是，SCFB可以在适度的缓冲要求和延迟下以接近最高效率的速率运行。我们还研究了基于128位块的新高级加密标准的密码模式的特点，并对SCFB操作模式的安全性进行了评论。
