摘要
AES加密算法是美国国家标准和技术委员会最新确定的一种加密算法标准。它的加解密速度快,算法安全性能好,是目前密码学界较为流行的算法。本文从AES算法的原理出发,分别对算法的加解密过程、加解密速度、安全性能及其在有线电视条件接收系统中的应用等方面进行了介绍。并且在VC环境下实现了该算法,对算法的加解密速度进行了测试。
AES encryption arithmetic is the new advanced encryption standard issued by National Institute of Standards and Technology. Now it is one of the most popular arithmetic in Cryptography field with high speed and well security. In this paper, based on the principle of the arithmetic, we described the encryptionand decryption process,the speed and the security of the arithmetic and the applications in the conditional access system. Besides, we accomplished the arithmetic using VC + +, and test the encryption and decryption speed of the arithmetic.
