| 摘 要： | 混沌系统具有对初值敏感、长期不可预测和伪随机性,在密码学中具备良好的应用基础.针对单混沌系统因计算机有限精度效应容易产生的混沌退化,必须应用一种双混沌映射的序列加密算法.该算法生成的序列符合局部随机性统计检验要求,具有良好的加密性能.

| Abstract: | Chaotic system is sensitive to the initial value, unpredictable in long cycle and pseudo randomness, which has good application in cryptography. It commonly leads to Chaotic degradation of singer chaotic system for computer＇s limited precision effect. This paper propose the sequence of a dual chaotic encryption algorithm. The algorithm generates a sequence with partial randomness testing, indicates good cryptographic properties. |
