Key management scheme of wireless sensor networks

Many applications of wireless sensor networks are based upon group communication model.How to establish a group key for encrypting group communication is therefore becoming an important concern to prevent an attacker from eavesdropping communications in wireless sensor networks.To support secure group communications in resource constrained wireless sensor networks,we proposed an efficient and scalable key management scheme that only used symmetric cryptographic algorithms and hashing function.This scheme can achieve forward and backward security.This scheme provides higher efficiency and is more suitable than previous group key management schemes for wireless sensor networks.
