基于CK模型的安全节点认证密钥交换协议

A secure node authenticated key exchange protocol based on CK model

无线传感器网络中的节点常常被部署在非安全的环境中,因而容易遭受假冒等安全威胁。为保护可信节点之间数据通信安全,基于计算性Diffie-Hellman假设,提出一种节点认证与密钥交换协议。推荐方案不仅能实现对参与节点真实身份的鉴别,而且生成一个参与方共享的秘密密钥,为参与方之间的数据交换建立一个安全的通信信道。并证明了推荐方案能实现CK模型下认证和密钥协商的协议的安全目标。此外,对安全属性的分析表明该协议具备前向安全、已知会话密钥安全、抗密钥泄漏假冒及未知密钥共享攻击的能力。

% Nodes in wireless sensor networks are often deployed in a non secure environment,which is vulnerable to security threats such ascounterfeiting . To protect sensor nodes deployed in insecure wireless sensor networlss from variety of malicious attacks,an authenticated key ex-change protocol is proposed,which security relies on Computational Diffie-Hellman Problem,and is better suited for Wireless Sensor Networks（WSN） to establish a shared session key between two adjacent nodes. The proposed protocol has someCK model, including perfect forward secrecy,known session key, unknown-key sh a re, key compromise impersonation resistance.
