由于传感器网络自身的一些特殊需求,加上其节点资源非常有限和网络特征的多样性,其安全问题在很大程度上不同于传统网络.给出了传感器网络的安全体系结构,力图对该领域的研究进行整体的描述.讨论了3个方面的问题:1)所采用的密码体制,如SKE,MAC,PKC等;2)密钥管理中的多种密钥建立算法;3)路由、能耗和容错等多因素相关的综合考虑.最后,简要介绍了其他一些安全问题以及该领域今后的研究热点.

Security issue of sensor networks is greatly different from that of conventional networks, in terms of its specific requirements, constrained resources of nodes, and variety of network characteristics. The security architecture of sensor networks is proposed, trying to outline a general illustration on this area. The following three topics are discussed: 1) Security primitives such as SKE, MAC and PKC; 2) Various keying mechanisms for the key management issue; 3) Joint considerations on network-related issues including routing, energy and fault tolerance.Other open security issues and further challenges are also addressed.
