BUILDING OF A KEY MANAGEMENT APPROACH OF EFFICIENT COMMUNICATIONS IN WIRELESS SYSTEMS

Abstract


In our work a certificate less effective key management method for supporting of secured communication within dynamic wireless network systems that are characterised by means of mobility of node. Dynamic wireless sensor networks facilitate mobility of sensor nodes; make possible extensive network coverage and more exact service than static sensor networks. For dealing of address security, management protocols of encryption key for dynamic wireless networks were proposed in past years based on symmetric key encryption and but they suffer from high communication transparency and needs huge memory space to store up shared pair wise keys. To the best of our information, resourceful as well as secure key management methods in support of dynamic wireless sensor networks were  not yet been proposed.  The proposed key management method manages efficient key updates when a node depart or else connect a cluster and make sure of  forward as well as backward key secrecy.
