Dynamic Key Management System for improving security in Three-Tier environment

Providing security in network field is not a easy thing in each and every network. For wireless sensor network the attackers easily apply their basic probabilistic and q-composite key pre-distribution scheme they compromise the network with the use compromising small fraction of nodes. After that introducing new concept of three-tier security scheme with mobile sinks. But this is not enough against the attacker’s harmful mobile sink replication attack. Now we introduce traditional scheme namely Dynamic key management for managing keys against attackers from cluster in a mobile environment. With a new scheme of Duplicated data sending through compromised nodes helps to save the data’s against a attackers. They won’t get any original data’s from this environment. So this concept is providing a network security and also increasing the network lifetime.
