摘　　要：随着物联网的广泛应用,传统的加密算法由于计算复杂、能耗过高已不能适用于资源受限环境中的安全应用,设计轻量级的分组密码算法成为近几年来密码学领域的研究热点。本文对现有分组密码算法的安全性分析方法进行了归纳,通过对现有算法的安全性分析,对验证算法的正确性和安全性提供了一些方法以供参考。With the wide application of the Internet of things, the traditional encryption algorithm cannot be appliedto the secure application of resource constrained environment because of computational complexity and high energyconsumption, the design of lightweight block cipher algorithm has become the research hot in the cryptography fieldin recent years. In this paper, the security analysis methods of the existing block cipher algorithm are summarized,and the security analysis methods of the existing algorithm methods has provided some methods and reference for ver-ifying the correctness and security of the algorithm.
