摘要
利用离散混沌映射进行信息的加解密,设计并实现了一个网络在线文字聊天保密通信系统,它不仅提供了一个实时通信平台,而且也保证了通信的保密性。系统采用倾斜帐篷映射,通过密钥同步方案,信息被实时加密后经TCP协议传输;而且由于混沌映射具有类随机特性及初值敏感性,传输的信息很难被破译,保密性较强。
An online chatting system with discrete chaotic map encryption/decryption method is designed and implemented for the network. Such system not only provides a real-time communication platform, but also ensures the security for communication. By the use of skew tent map, with key synchronization scheme, the input text can be real-time encrypted and the cipher text is transmitted via TCP. With the properties of randomness of the chaotic map and its sensitivity on the initial conditions, the encrypted transmitting messages are secure and difficult to be eavesdropped.
