摘　　要：大规模传感器节点通常被部署在有潜在不利因素、甚至敌对的环境中,因而传感器网络安全问题尤为重要。传感器节点受成本、体积和功耗的限制,其能量、计算能力、存储能力及通信能力都比普通计算机要弱很多,这使得无线传感器网络中的密钥管理协议的设计面临许多新的挑战,因而提出了适合于无线传感器网络环境的轻量级的、高效的密钥预分配方案,该方案融合了基于CA的公钥认证框架和基于身份的公钥认证框架二者的优点。进一步地,基于2次剩余理论,对所设计的方案给出了高效实现。Large-scale sensor nodes were usually deployed in potentially adverse or even hostile environment, so the security in these networks was very important. Due to its constraints on node cost, size and power dissipation, sensor＇s energy and capabilities on computation, storage and communication were considerably weak compared with general com- puters. It leaded to many new challenges for designing of key management protocols in WSN. Therefore, a lite-CA based key pre-distribution scheme was suggested. The traits of CA-based authentication framework and identity-based authentication framework were combined by this scheme. Further, the scheme was efficiently implemented based on quadratic residue theory.
