密码学是一门交叉学科,融合了计算机、数学、信息论等多个不同学科[1],它由密码编码学和密码分析学组成,其中,密码编码学主要研究对信息编码以实现信息隐藏,而密码分析学主要研究通过密文获取对应的明文信息。密码学研究密码理论、密码算法、密码协议、密码技术,以及密码应 Cryptography is an interdisciplinary, which integrates many different disciplines such as computer, mathematics and information theory [1]. It consists of cryptography and cryptanalysis. Among them, cryptography mainly studies how to encode information to realize information hiding, Cryptanalysis, on the other hand, focuses on obtaining plaintext information through ciphertext. Cryptography studies cryptography, cryptographic algorithms, cryptographic protocols, cryptography, and cryptography
