摘要: 将传统的对称加密方法与基于身份的公钥加密系统相结合,设计了一种基于身份的认证加密方案,该方案用椭圆曲线上的双线性映射构造,其安全性基于双线性的计算Diffie-Hellman假设和单向的Hash函数。与以往的文献中基于身份的公钥加密方法相比,该方案系统初始化简单、加密/解密效率高,具有较低的通信成本。

关键词: 基于身份加密, 认证加密, 对称加密

Abstract: The traditional symmetric encryption is integrated into identity-based cryptographic systems, a new encryption scheme, a new identity-based authenticated encryption scheme based on the computational Diffie-Hellman assumption is presented. It includes setup, key generation, encryption and decryption with message authentication. Compared with existed literature, the scheme has lower time complexities and communication costs. It is simple and efficient.

Key words: Identity-based encryption, Authenticated encryption, Symmetric encryption
