Threshold Cryptography and Authentication in Ad Hoc Networks Survey and Challenges

The dynamic and cooperative nature of ad hoc networks present challenges in securing these networks. There are recent research efforts in securing ad hoc networks. Amongst security approaches, there are threshold cryptography and authentication. In this paper we survey the threshold cryptography based schemes and the authentication schemes that have been proposed to secure ad hoc networks. We conclude this paper and identify the challenges and open research areas associated with each of these approaches.
