Use Data-depend Function Build Message Expansion Function

ZiJie Xu and Ke Xu

Abstract

We had found functions can be used to fix bits [2] by given differences. We use these functions build a message expansion function. In the message expansion function, there are some bits include message bits and incremental bits produced from message bits, these bits will be used as parameter of date-depend function. This message expansion function will fixed at lease n × 5.5 bits with given differences, and any message modification will affect at least 8 data-depend function parameter.
