In wireless ad hoc networks, the route discovery process or the data forwarding process is vulnerable to attackers. In this paper, we address the data forwarding security problem and propose a light-weight secure data forwarding protocol, which utilizes one-way hash chains to achieve the message integrity, where the intermediate nodes can effectively detect the fault link and the source node of the...
The kernel function of the Diffie-Hellman (DH) protocol is a modular exponentiation over finite field with high computational complexity. In this paper, we propose a novel key generation algorithm for DH agreement that derives computational efficiency from constructing a parallel architecture. Compared to the serial structure for traditional binary representation (BR) method, our algorithm is significantly...
Against the problems emerged in protocols presented by N. Modadugu, D.Boneh and M. Kim (2000), new server-aided public key generation protocols on low-power devices are proposed in this paper. The protocols are secure against some passive attacks, such as "collusion attack" and "the third party attack". In addition, efficiency of primality test on low-power devices is improved...
