Secure Communication in Mobile Ad Hoc Network using Efficient Certificateless Encryption,

Abstract

Establishing secure communication in a wireless network such as Mobile Ad Hoc Network is particularly challenging because: (i) the network is self-organizing; (ii) messages are broadcasted; (iii) messages travel in a hopby- hop manner; (iv) nodes are constrained in terms of computation and battery power. We propose an efficient Certificateless Encryption scheme which is optimized for Optimized Link State Routing based Mobile Ad Hoc Network environment. Further, we couple the idea of Resurrecting Duckling with the scheme to achieve efficient key establishment. We also show the security of the scheme in random oracle model assuming k-Bilinear Diffie-Hellman Inversion problem is hard.
