无线传感器网络节点间认证及密钥协商协议

Authentication and Key Negotiation Protocol Between Two Nodes of Wireless Sensor Networks

无线传感器网络的特性使它面临着比传统无线网络更大的安全挑战,其安全解决方案必须兼顾安全性和系统性能等因素。节点间认证及密钥协商是构建安全网络最基本的协议,是密钥管理协议和安全路由协议等的实现基础。很明显,包括传统Adhoc在内的各种无线网络领域中的安全认证及密钥协商机制都无法适用于无线传感器网络。为此,在充分考虑无线网络攻击方法和无线传感器网络自身特点的基础上,结合基于ID的公钥密码技术,提出了椭圆曲线双线性对上的无线传感器网络节点安全认证及密钥协商协议。分析发现,该协议不仅满足安全性要求,同时,能够适合无线传感器网络的特殊应用要求。

Due to their own characteristics, wireless sensor networks are facing more security challenges than traditional networks. Their security mechanism should take into account both the security and the system performance. Authentication and key negotiation is an elementary protocol in constructing a secure network system, and it is the implementation foundation of the key management protocol and the secure routing protocol. By all appearances, most of the existing wireless networks authentication and key negotiation protocols are inapplicable to wireless sensor networks, including those in traditional Ad hoc networks. Motivated by these concerns, on the enough consideration on the attack methods for wireless networks and the characteristics of wireless sensor networks, a node-to-node authentication and key negotiation protocol is proposed, in which the ID-based public-key cryptography and the ellipse curve bilinear pair are adopted. Analyses show that this protocol can be used to guarantee the security of wireless sensor networks, and at the same time, it can meet the special application requirements of wireless sensor networks
