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