SNEED: Enhancing Network Security Services Using Network Coding and Joint Capacity

Network security protocols depend mainly on developing cryptographic schemes and using biometric methods. These have led to several security protocols that are unbreakable based on difficulty of solving untractable mathematical problems such as factoring large integers. In this paper, Securing Networks by Employing Encoding and Decoding (SNEED) is developed to mitigate single and multiple link attacks. Network coding and shared capacity among the working paths are used to provide data protection and data integrity against network attackers and eavesdroppers. It is shown that SNEED can be implemented easily where there are k link disjoint paths between two core nodes (routers or switches) in an enterprise network. Finally, SNEED can be incorporated into various applications such as on-demand TV, satellite communications, and multimedia security.
