本文介绍了在JAVA环境下如何实现IDEA对称加密算法。由于电子商务和电子政务的普及，安全加密技术在其中应用非常广泛，对安全加密技术的要求也很高。目前在JAVA环境下实现IDEA加密具有很多的优势，因为JAVA是基于面向对象的编程语言,并且由于它的平台无关性能被大量应用于Internet的开发。-This paper presents the Java environment IDEA how to achieve symmetric encryption algorithm. As e-commerce and e-government popular, security encryption technology, which is widely used for security encryption technology requirements is also high. In Java environment under IDEA encryption has many advantages, because Java is based on object-oriented programming language, and because it is platform independent performance was widely used in Internet development.
