Abstract:
A new efficient ID-based authenticated encryption scheme is proposed, in which some characteristics of bilinear map are used. As the authentication and recovery are separated in this scheme, anyone can identify the source of the ciphertext, but only the receiver can recover the plaintext. What’s more, the proposed scheme is also very efficient regarding to the computation costs and the communication overheads.

摘要: 利用椭圆曲线上的双线性映射的特性,提出了一个新的基于身份体制的安全有效的认证加密方案。该方案与其它方案相比最显著的优点在于在基于身份的密码体制上实现了认证部分与消息恢复的分离,该体制在拥有基于身份密码体制的独特优点的同时,又达到任何第3方都可以认证密文,但同时又只有指定的接收者才有能力去恢复出明文的效果。此外,该方案具有很高的安全性和效率。
