Efficacy of multivariate cryptosystems for DWSN

Dynamic wireless sensor networks (DWSN) is a network of thousands tiny sensor devices deployed in a hostile environment. This network is mainly used for large scale environment monitoring. Security is vital for such networks. However, traditional cryptographic algorithms are resource intensive. They need large computation and require large memory and bandwidth. To address the problems of security in resource limited DWSN, different types of multivariate cryptosystems are proposed. The viability of multivariate cryptosystems for DWSN are examined. Results have indicated that the multivariate cryptosystems are attractive for DWSN. In this paper, efficacy of different multivariate cryptosystems for DWSN has been evaluated. In contrast to other multivariate cryptosystems schemes, rainbow multivariate scheme requires low computational power and reduced storage overheads. Simulation results also show that rainbow multivariate scheme can maximize throughput to achieve short latency for a particular interval of time.
