在分析现有无线传感器网络随机预分配密钥算法的基础上,通过同时引入q合成技术、多路增强技术与单向密钥序列技术,提出了增强的随机预分配密钥算法H-RKP,并以节点俘获攻击为例对其安全性进行了分析,证明该算法可以进一步提高现有随机预分配密钥算法的安全性。Based on the analysis of the existing Random Key Predistribution (RKP) schemes in wireless sensor network, a hash random key predistribution scheme H-RKP is proposed by introducing multi-path reinforcement scheme, q-composition scheme and one-way cryptographic hash function based random key predistribution algorithm. The security performance of the scheme under node capture attack is analized. The H-RKP scheme can further improve the security of the existing RKP schemes.
