基于对称密码体制的通信加密方案设计与研究

摘要

Cryptography is an important mean to realize communication security, and communication system is need to adopt the appropriate encryption techniques to accomplish communication in an insecure channel. This paper designed three kinds of communication encryption schemes based on symmetric cryptography, demonstrated and compared the encryption schemes, provided research idea for the design of encryption scheme for the future communication system.%加密是实现通信保密的一种重要手段，通信系统需要采用适当的加密技术以完成在一个不安全的信道上的通信。文章设计了三种基于对称密码体制的通信加密方案，并论证比较了三种加密方案，为今后通信系统加密方案的设计提供了研究思路。
