摘　　要：密码算法的实现效率是衡量一个密码算法好坏的重要指标。传统密码算法是基于比特(A5算法)、字节(AES算法)、32位字(IDEA)设计的,软件实现速度相对较慢,而在最近的CAESAR竞赛中,基于快速指令集设计的一些算法,例如MORUS、AEGIS,它们的软件实现速度是非常快的。本文选择了两种非常有代表性的指令集SSE2与AES-NI进行研究,研究这两种指令集在密码算法中的使用方法,以及这些指令集应用到密码算法中会提升效率,通过对这两种指令集的研究,指出了使用指令集在密码算法中的优势。The performance of the cryptographic algorithm. The design of traditional cryptographic word （IDEA）. Their software performance is algorithm is an important standard of measuring an algorithm is based on the bit （A5）, byte （AES） or relatively slowly. However, in the recent CAESAR competition,some cipher was designed based on fast instruction set, just like MORUS and AEGIS. Their performance was very fast. In this paper, we choose two typical instruction sets SSE2 and AES-NI. Studied the methods of two instruction set used of cryptographic algorithm, and the performance of the instruction sets. Through the study of these two kinds of instruction sets, points out the advantage of the instruction sets used in cryptographic algorithm.
