摘　　要：公钥密码CS能有效抵抗自适应选择密文攻击 ,ECC具有很高的每比特加密强度 ,对称密码AES加密速度快且能抵抗已知的各种攻击 ,本文在这三种密码优势互补基础上提出一种混合密码 ,它集密钥交换、签名验证以及数据加解密功能于一体 ,既安全又实用。As we know CS is provably secure against adaptive chosen ciphertext attack,ECC provides better strength-per-bit than others,and AES offers high speed and resistance against all known attacks.To combine their advantages,a new hybrid cryptosystem based on CS,ECC and AES is proposed and analyzed in this paper.The scheme aggregates key exchanging,signature verifying and dada encrypting in one algorithm.It is quite secure and practical.
