Key Management Scheme Based on Pairewise Key in WSNs
Wang Yu · Communications technology · 2007
WSNs require cryptographic protection of communications between sensor nodes.BPKP based on Pairwise Key Pre-distribution key management scheme has implemented such functions as initial key-pair vectors distribution,the construction of communication key-pair vectors,and communication key-pair vectors updating.Simulation,analysis comparison with other pre-distribution scheme indicate that the BPKP scheme has dramatic advantage in network connectivity,security and energy consumption.
