本文详细地论述了透明密钥和全透明密钥问题,证明了DES中至少存在四个透明密钥,并建立了全透明密钥存在性和等值密钥存在性之间的一定关系。
This paper discusses the problem of transparent keys and full transparent keys in detail. It proves that there are at least four transparent keys in DES and establishes a certain relationship between the existence of fully transparent keys and the existence of equivalent keys.
