Abstract: The chaos is very sensitive to initial conditions and high-blooded randomicity, so it can be used in encrypt information. This paper introduces a new undeniable signature scheme based on chaos. The experiment results show that it has the characteristic of high security, being prone to implement.

Key words: Chaos, Digital signature, Undeniable

摘要： 混沌系统由于对初始值和参数的敏感依赖性和良好随机性，可以应用于保密通信。该文提出了基于混沌理论的不可抵赖数字签名方案。实验结果表明，该方案易于实现且有较高的安全性。
