摘要
研究了E-G密钥预分配算法的原理,基于Blom密钥预分配模型提出了一种新型的密钥分配算法。该算法通过将节点部署在一个正六边形区域内,每个簇内均采用预共享密钥建立配对密钥,簇间采用Blom密钥预分配模型建立配对密钥。新算法的安全性优于E-G算法,且接近于CHAN提出的PIK算法;且连通率优于E-G算法和PIK算法。
This paper studies the E-G key predistribution algorithm principle,and a new key distribution algorithm based on the Blom key predistribution model is proposed.The nodes is deployed in a hexagonal area.Each cluster uses preshared key to establish key pair,Blom key predistribution model is used in the establishment of key pair among clusters.The new algorithm is superior to E-G algorithm,and close to the PIK algorithm proposed by CHAN in security.and its connectivity is better than E-G algorithm and PIK algorithm.
