Lightweight Secure and Scalable Key Sharing Protocol for Wireless Sensor Networks

Munir Hussain, Khalid Khan

Abstract

Wireless Sensor Networks (WSN) technology is still immature and thus faces a variety of problems due to limited memory, CPU and battery power resources. WSNs are prone to active and passive attacks. While the former is capable of affecting minimal resources, the latter type of attack is difficult to launch but very powerful in terms of affecting critical resources. Most shared key security protocols used in WSNs are not scalable as they depend upon third party or KDC. Although in some situations this concept works well, besides reducing scalability, finding a trustworthy third party is also very difficult in KDC concept of key sharing. This paper gives a brief overview of WSNs, posed security threats to these networks and relevant security issues. This paper also brings in a novel key sharing model for traversing secret key in WSNs that does not depend on third party concept and hence it is a more scalable and secure.
