A proposed algorithm for securing OSPF with using Symmetric key and Encryption techniques based on Image

Network reliability is becoming increasingly important issue today. So to remain resistant to attacks is the fundamental thing for it. Securing routing protocol involves protecting the authenticity and integrity of routing protocol messages. The protocols which used as network routing deployed in internal networks is Open Shortest Path First Protocol (OSPF). OSPF is based on the relative costs of transferring information between routers and networks. In OSPF, a group of routers collaborate, exchange routing information, and forward packets for each other. Attacks on routing protocol OSPF can be launched either as insider attacks or as outsider attacks. Earlier works have addressed these two problems independently with many interesting solutions. Like Digital Signatures, MD5, MAC, RSA etc. Due to the nature of these solutions, network architects cannot deploy without increasing the overhead on the network. Also they all are having their own advantages as well as disadvantages. So in this research the proposed algorithm is working for this solution. Use of Symmetric Key techniques, Diffie Hellman and Image based encryption makes the mechanism more secure against attacks.
