摘要
针对LEAP方案存在的一个缺点,即在密钥建立过程中,由于一个节点被俘获而导致网络中其他节点的安全受到威胁,提出一种基于二元对称多项式的无线传感器网络密钥管理方案,分析表明该方案不仅能克服LEAP方案的缺点,而且还具有抗捕获能力强、能够抵抗合谋攻击和Hello Message攻击等优点。与LEAP方案相比,其存储代价和通信代价相同,计算代价略有增加。
LEAP scheme has a disadvantage that during key establishment phase,due to a sensor node is captured,the security of the other sensor nodes in the whole network is threatened.This paper proposes a key management scheme for Wireless Sensor Network(WSN) based on symmetric bivariate polynomial.The proposed scheme not only overcomes the defect in LEAP scheme but also has some advantage that well prevents capture capacity,resists conspiracy attack and Hello Message attack.Compared with LEAP scheme,the scheme has the same storage and communication cost and has a little higher computation cost.
