本文提出了一类新提出的密码体制的改进方法。作为补救，我们采用了分布均匀的分段线性混沌映射(PLCM)。实验结果表明，PLCM的应用不仅保证了密码体制的可行性，而且提高了密码体制的加密速度。此外，还采用了一种新的动态查找表设计作为保证密码系统安全性的有效方法。
In this paper, a modified method of a class of recently proposed cryptosystems is presented. As a remedy, the piecewise linear chaotic map (PLCM) which has a uniform distribution is adopted in our method. The experimental results demonstrate that the application of PLCM can not only ensure the feasibility but also promote the encryption speed of these cryptosystems. Moreover, a new design of dynamical look-up table is used as an efficient way to ensure the security of our cryptosystem.
