本文论述了通用数据加密算法适宜采用的密码体制和密钥量,重点论述了分组长度,并提出了用以区分不同系统的结构变异子算法的设想,以及于算法与主算法的接口方式。
In this paper, we discuss the cryptosystem and key volume that are suitable for common data encryption algorithms. The length of the packet is emphatically discussed, and the assumption of structural variant sub-algorithms for distinguishing different systems is proposed and the interface between the algorithm and the main algorithm is proposed.
