An Efficient Secure scheme for Wireless Sensor Networks

Recently, using Wireless Sensors Networks has increased rapidly in different domains. This advance has provides many solutions in several everyday life fields. Nevertheless, many problems of security and especially energy consumption have emerged. Due to this reasons many works propose solutions to increase the level of security and especially secure group communications. The communication requires common group key for protection of control messages and data reports. The group key should be updated when a node is compromised or a node leaves the group or a new node joins the group to achieve forward and backward security. It is in this context that our works was oriented to propose a new authentication scheme to improve the rekeying message authentication. Experimental results using real platform TelosB motes with tinyos operating system validate the efficiency of our proposed solution.
