MultiSECPKC: An Authentication Protocol Based on Public Key Cryptography

Authors : P. Vijaya Lakshmi, D. Somasundareswari and V. Duraisamy

Abstract: Providing security service in wireless sensor networks using authentication techniques turns out to be a non-trivial task due to network resource constraints. To improve the network security it is often necessary to combine intrusion detection techniques with the key management protocols. Several symmetric key cryptographic solutions proposed earlier are inefficient against node compromise attacks due to delay in the disclosure of secret keys. On the other hand, conventional public key cryptographic techniques suffer from large key sizes introducing large communication overhead and delayed authentication. Researchers propose MultiSECPKC, a highly reliable authentication protocol based on public key cryptography to provide an energy efficient secured environment against node compromise attacks which would otherwise waste the energy of network resources. Any compromised node is detected and isolated in the initial stage itself with minimum overheads and energy consumption. The best and fresh route is formed using intermediate nodes between the source and the sink. In addition, this scheme exploits the use of only one ECDSA signature to authenticate the messages which in turn reduces the overhead of the sink in performing signature verification. Simulation results show that the proposed scheme can provide very low overheads in terms of storage, computation and communication with high energy saving and high reliability. The proposed scheme is more resilient to node compromise attacks and can be applied for different routing techniques for sensor networks.
