摘　　要：文章讨论了一类热流密码体制线性模型,设计了加、解密问题的C N差分格式算法,并用Matlab6.5编写了算法的计算机模拟软件,在大量模拟试验的基础上我们得到了不同密钥函数对加、解密作业影响的一些规律性结论,为该密码体制的实际应用奠定了基础。This paper deals with a class of linear cases of heat flow cryptosystems.The Crank-Nicolson difference schemes for encryption and decryption problems are established, and then a computer simulation software is established by Matlab 6.5 based on the schemes. Under the analysis of plenty of results of computer simulation, we draw some conclusions on the in fluence of the different key functions over encryption and decryption, which establish the base for its application.
