摘要：In today’s world, we always try to be safe and protected when we communicate with others. But when Mobile Ad-Hoc Networks (MANETs) are considered, they are known to be unprotected due to the nature of message propagation and their openness. For data security we can use Symmetric key cryptography but it has various problems in MANETs like key distribution, key management and scalability problems. Public key cryptography provides solution for the problems raised in Symmetric key cryptography with authenticated key agreement protocols. But implementation of PKC based protocols in MANETs is very difficult because of its constraints like mobility of nodes. In this paper, we propose a new hybrid authentication protocol for MANETs. This protocol uses RSA algorithm concept for authentication between two nodes and protocol security is based on elliptic curve discrete logarithmic assumption. This protocol is energy efficient and uses low memory as we use the concept of Elliptic Curve Cryptography (ECC).
