PRZ style CFB mode description preferences1998-02-12 13:09:32Some time ago Hal asked which of two descriptions for the CFB mode Phil Zimmermann invented were preferred. (The CFB mode in summary does not use a fixed feedback length in bits, as is normal, but varies that feedback length at semantic boundaries in the plaintext). My preference is greatly for the description referring to the bulk of the data encryption as CFB-64, and the re-syncs as having CFB-16 applied to them. (Or CFB-whatever). Adam
