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