高级加密标准JAVA实现与应用-用AES加密聊天内容 摘       要    随着网络应用的不断发展，在网络上办公、做事、购物、交友的需求是越来越大。而网络发展的初步是为了资源共享。它对于保护隐私方面的能力就显得很薄弱。而这些责任将归咎到对于网络应用开发的程序员手中了。越来越多的程序员使用1些高效安全的加密方法对重要的信息进行保护。本设计着眼于网络聊天内容的加密设计,通过使用高级加密标准对其进行加密,用公钥密码体制中的RSA公钥密码方式加密高级标准的密钥并进行传送.本设计使用JAVA语言来进行开发.其实现的数据加密功能的程序具有高效、安全、跨平台的特点。此软件的开发是在windowsXP下进行的，实现的功能有：aes加密与解密模块，用户上线，离线，断线，设定自己的图标、昵称、离线回复，对聊天内容进行加密传送等。采用AES加密数据，RSA加密AES的密钥的方式，使些聊天软件的安全性大大提高，具有安全、易用等特点。关键字: 高级加密标准；公钥密码体制；网络聊天  AbstractWith the continual network application development on the network office, work, shopping, friends, the demand is increasing. And the initial development of the Internet in order to share resources. It for the protection of privacy on the capacity is very weak. And these duties will be to blame for network application development programmers of the hands. More and more programmers use a highly effective and secure method of encryption of important information protection. Focus on the design of network contents of the encrypted chat design, through the use of its Advanced Encryption Standard encryption. using public-key cryptosystem the RSA public-key cryptosystem Advanced Encryption Standard methods of transmission and key. The design JAVA to language development. achieve its data encryption process is efficient, safe, cross-platform features. This software development is carried out in windowsXP, the functions are : aes encryption and decryption modules, users on the line, off-line, lost, set their own icon, nicknames, off-line replies to chat content such as encrypted transmission. Using AES data encryption, RSA encryption AES key ways in which some chat software security is greatly improved, It is safe, easy-to-use features.Keywords: Advanced Encryption Stantard;public-key cryptography;Chat on line
