Implementation of security features in MANETs using SHA-3 standard algorithm

In Secure Hash Algorithm-3 standards, the functions are based on instance of the KECCAK algorithm. In this paper, we have implemented Secured Hash Algorithm (SHA3-256) for secured routing in hybrid routing technique of Mobile Ad hoc Networks (MANETs). We have used Hashed Message Authentication Code (HMAC) to achieve data integrity and authentication. The hybrid routing technique which we have used was Zone Routing Protocol (ZRP), a hybrid MANET is routing protocol using Network Simulator 2 (NS2). This paper implements a HMAC-SHA3-512 algorithm in ZRP which leads to higher throughput and packet delivery fraction but at the expense of the increased end to end delay. From our performance analysis using 64-bit Intel Processor, it shows that the cost of implementing a HMAC-SHA3-512 algorithm gives 50% performance improvement over similar implementations of HAMC-SHA3-256.
