Dynamic Routing and Agent Technology Based Security Enhanced Data Delivery with Public Key Cryptography

Network security measures are needed to protect data during their transmission in any type of network . In this paper we propose a security enhanced dynamic routing algorithm that explores the existence of multiple routes and forces packets to take alternate paths probabilistically with the newly constructed routing table. It makes the interception and eavesdropping maximally difficult and also increases the throughput as they make use of multiple paths. It balances the load in the nodes to avoid congestion with the help of mobile agents. This paper also provides the security services such as integrity, authentication, and authorization through public key cryptography to the proposed dynamic routing table to be exchanged among nodes against various attacks.
