Symmetry Key Establishment Scheme for Wireless Sensor Network
Ling Zhang · Jisuanji gongcheng · 2011
The special characteristic of Wireless Sensor Network(WSN) asks the key establishment scheme for WSN to be secure and effective.According to the past research,the key-pool based key establishment scheme is fit for WSN.However,the secure link connectivity of WSN is not so good.The symmetric pair-wise key establishment scheme based on the bivariate polynomial can get a high secure connective link rate,but it does not secure enough.Based on the two schemes,a new key establishment scheme is presented.Analysis and simulation results show that this new pair-wise key establishment scheme makes much more improvement than the classical pair-wise key establishment scheme on the security,the connectivity,the scalability,the effectiveness and so on.
