摘要:
作为主要密码技术之一的序列密码，它的安全强度完全取决于其所产生的伪随机序列的好坏。而混沌系统具有对初始条件敏感性、随机性、相关性等优良的密码学性能，能够产生性能良好的伪随机序列，所以很适合于序列加密。文中分析了基于Logistic混沌映射的加密算法原理；给出了一个基于该算法的具体加密／解密算法；利用VFP工具具体实现了加密／解密算法，并用该算法对一个具体实例进行了加密。实验结果表明混沌加密算法完全可以满足VFP数据库应用系统保密的要求
Abstract:
The security of stream cipher,which is known as one of the main cipher techniques, dependents completely on the quality of generated pseudo - stochastic sequences. Chaotic systems are sensitive to the initial condition, randomness and correlativity. They can produce good pseudo- stochastic sequences. Therefore, these systems are suitable to the stream cipher. The paper analyses the principle of the chacs encryption algorithm based on Logistic formula firstly. Then, a particular encryption/decryption algorithm is presented. Moreover,the encryption/decryption algorithm is realized by the VFP. Finally,an example is given to demonstrate our method via the VFP. The result shows that chaos encryption algorithm can guarantee the security of the VFP database application system
