高级加密标准AES在JCE加密构架下的实现

Implementation of Advanced Encryption Standard(AES) based on Java Cipher Extension(JCE) Architecture

为了解决DES等旧的加密算法已经走向衰落的情况,分析了高级加密标准(AES),AES是美国国家标准和技术研究所(NIST)选定的一种高强度加密算法。文中探讨了将椭圆曲线加密(ECC)和AES混合的加密方法,并说明了加密流程。进一步在JCE框架下实现了对AES加密算法的Java安全结构扩展。最后,总结了该方法的优点。

To resolve the weakness of old ciphering algorithms such as DES, Advanced Encryption Standard （AES） is proposed, which is adopted by National Institution of Standard and Technology （NIST） cryptographic algorithm with higher intensity. A method in combination of both ECC and AES is discussed, including the key exchange management and specific encrypt process of the AES algorithm. Furthermore, an approach to extend the Java Security Architecture to support AES based on JCE is presented. Finally, this paper sums up the advantages of this approach.
