A Grou PKey Management Scheme Based on Secret Sharing in WSNs
LV Yuanfang · Microcomputer applications · 2010
A grou Pkey management scheme based on secret sharing in wireless sensor network is proposed, which is called GKMSSS. GKMSSS uses LEACH protocol to make the network clustering. Based on the theory of secret sharing and the principle of symmetric key encryption, the grou Pkey components are stored in the various grou Pmembers in a distributed manner. And the key pre-configured, hierarchical key generation, the network sub-clusters, key generation and distribution, key updates, grou Pof new members joining and members of the grou Pexiting are successfully achieved. Through correlation analysis and experiments, it shows that GKMSSS effectively assures the grou Pcommunication forward secrecy, backward secrecy and good anti-prisoner capacity of the node on condition that the storage overhead and communication overhead is in an acceptable situation respectively.
