Abstract As MANET is ad hoc, dynamic topology is a key function of this network, making MANET prone to different security threats. Although numerous routing protocols and methods exist to find and alleviate Sybil attacks in MANET, the hash function-based DSR protocol is a completely new idea. In this research article, we have introduced a new cryptography-based dynamic source routing protocol, named CRYPTO-DSR. First, we calculated the minimum distance of the route from the origin to the target node using Johnson’s algorithm. We then secured the packets full of data inside the nodes using the hash function technique. After decryption, if the packets are found to be accurate, they are forwarded to the subsequent node and so on until they reach the destination. We compared our modified DSR protocol with the normal one and concluded that our crypto-based DSR protocol is much more secure and environmentally friendly than the traditional one in relation to performance, as measured by throughput, end-to-end delay, and the data transfer success rate during a Sybil attack.
