基于JCE的数据加密密钥交换实现技术

在介绍了XML的安全特性和其加密规范后,从Diffie-Hellman密钥协商的生成原理出发,运用XML加密规范所提供的对数据对象进行密钥协商的机制,并以经典的D-H密钥协商为例,依据规范所制定的原则,运用JCE所具有的安全特性为实现技术,就如何对密钥协商交换进行了探讨,从而为XML加密规范的实际应用探索了一种方式,并以此说明建立自主加密扩展的重要意义。

Implement for Key Exchange Agreement in Data Encryption Based on JCE

After describling XML and its XML encryption specification, it researchs on encryption key agreement for XML data object based on specification above from Diffle-Hellman key agreement. As an example, It analyses key generation machnism about Diffie-Hellman agreement using JCE security characristics and according to principle of XML specification. So it explores a method to use XML encryption specification, and want to explain that it is important to build own Java Cryptography Architecture with explensive features.
