摘要/Abstract

摘要： 提出一个消息策略基于属性的密钥协商协议。基于属性的密钥协商协议具有很多特性,其中主要的特性是模糊鉴别。讨论了模糊鉴别特性在密钥协商协议中的应用,并具体构建了一个两方的消息策略基于属性的密钥协商协议,所实现的消息策略为两值属性上的与门访问结构。此外,基于判定双线形Diffie-Hellman假定,在标准模型下证明了协议的安全性。

Abstract: We proposed a message policy attribute based key agreement protocol．Attribute based key agreement protocol has many characteristics,the main of which is fuzzy identification．This paper discussed the application of fuzzy identification in key agreement protocol,and constructed a two-party message policy attribute based key agreement protocol,where the message policy is And-gates on two valued attribute．In addition,the new protocol was proved secure in the standard model under the decisional bilinear Diffie-Hellman assumption(DBDH).

Key words: Message policy,Attribute based encryption,Key agreement protocol,Security proof,Standard model
