A chaffing-and-winnowing is a cryptographic scheme which does not require encryption but instead use a message authentication code (MAC) to provide the same function as encryption. In this paper, we discuss and introduce some new insights in the relationship between unconditionally secure authentication codes (A-code) and unconditionally secure encryption schemes through observing the mechanisms of chaffing-and-winnowing. Particularly, we show through chaffing-and-winnowing that an A-code with… CONTINUE READING
