摘要
通过加密实现私有数据的授权访问是一项很重要的技术。如今,密码学意义上安全的DES,RSA加密标准得到了广泛应用。Baptista提出的混沌加密是密码学史上新的发展方向,它继承了混沌系统的重要特性,比如对初始值极度敏感。在描述混沌系统的理论基础上提出了混沌保密系统的一种结构,并使用蔡氏电路实现了文本、图片的保密通信。
Cryptography is an important technique to keep private data secretly in order to avoid unauthorized access. Traditional encryption methods such as DES, RSA etc... are widely used today and it seems to be computationally secure. Baptista proposed a Chaotic Encryption Method, which seems to be much better than traditional encryption methods used today. Chaotic encryption makes use of chaotic system properties such as sensitive to initial condition and lost of information. In this paper, a data encryption protocol is provided and implemented with Chua's circuit to image and text.
