一个基于属性的密钥协商协议
An Attribute-based Key Agreement Protocol
摘要
Abstract
This paper proposes a two-party key policy attribute-based key agreement protocol on the basis of attribute based encryption scheme. It discusses some properties and potential applications of key policy attribute based key agreement protocol with the characteristics of fuzzy identification, key policy is access tree structure. It analyzes the security attributes of the protocol and gives the rigorous proof of security. Results show that, comparing with previous protocols, the new protocol achieves more complex access structure and is proved secure in the standard model under the Decisional Bilinear Diffie-Hellman(DBDH) assumption.关键词
