Rayala Upendar Rao . Secure Routing in Cluster based Wireless Sensor Networks using Symmetric Cryptography with Session Keys. International Journal of Computer Applications. 55, 7 ( October 2012), 48-52. DOI=10.5120/8770-2696
Wireless sensor network is an emerging technology, uses in many applications like boarder area enemy tracking system, fire alarm system, etc. Sensors are low power devices which possess huge attacks. These low power devices are not suitable for complex cryptographic algorithms. In this paper we implemented symmetric key algorithm with session keys. This concept carry better security compared previous secure routing algorithm in cluster wireless sensor networks. Here the forwarding node will check the both secrete global key and session key. It also checks one more parameter that is loading time of node, ensures more security.
