AES is used for digital audio encryption, while ECC is used for procedure of key cooperation. A complete solution for security of mobile communication is proposed. The algorithm AES (Advanced Encryption Standard) is introduced firstly.

• 主要实现了两个加密算法,即语音加密过程采用的AES(Advanced Encryption Standard,高级加密标准)加密算法与密钥协商过程所使用的ECC(Elliptic Curve Cryptography,椭圆曲线密码学)加密算法。
