Improving HBQ Authentication and Access control in wireless sensor network

Wireless sensor networking continues to evolve as one of the most exciting and challenging research areas of our time. In the real world, there are many applications of wireless sensor networks that collect and send sensitive important information to the Base Station. Due to the wireless communication´s insecure nature and considering the fact that sensor nodes always are distributed in a hostile environment, having well implemented security scheme is very essential. Considering important security services like Authentication and Access control, we proposed a new security scheme for these networks. In the proposed scheme, Bloom Filter data structure has been used for pre-Authentication and Access controls; also for main Authentication service the Elliptic Curve Diffie-Hellman scheme has been implemented. The implementation results show that our scheme has significant improvement comparing to HBQ scheme regarding power and time consumption.
