适用于智能电网的三方认证密钥交换协议

Tripartite authenticated key exchange protocol for smart grid

大部分现有智能电网环境下的认证方案都存在需要人工参与或运行性能不高的缺点,不能满足智能电网的实际需求。鉴于此,提出了一种新的三方认证密钥交换协议,用于智能电表、服务提供商和控制中心三方之间的认证和密钥建立。基于物理不可克隆函数,去除了需要人工参与协议运行的缺陷。结合BAN逻辑和非形式化分析方法,对协议的安全性进行了证明。与同类代表性协议相比,所提协议具有更好的安全性和更高的效率。

Most of the existing authentication schemes in the smart grid environment have the drawbacks of requiring manual participation or low performance,and thus do not meet the practical needs of smart grids.A new tripartite authenticated key exchange protocol was proposed for authentication and key establishment between three parties:smart meters,service providers and control center.The protocol was based on a physical unclonable function,which removed the drawback of requiring manual participation in the operation of the protocol.The security of the protocol was demonstrated by combining BAN logic and non-formal analysis methods.Comparing with similar representative protocols,the proposed protocol has better security and higher efficiency.
