Abstract
It has been shown that network coding can effectively improve the throughput of multicast communication sessions in directed acyclic graphs, achieving their cut-set capacity bounds. However, network coding is highly susceptible to eavesdropping and pollution attacks in which malicious nodes attacks cannot be prevented. In this paper, we propose several ways to enhance the security and reliability of random networking coding transmission. Schemes which encrypt the random coefficients and the coding payload could ensure the information has a relatively low probability to be cracked. We also implement the reliable transmission by forward error-correction. It has been shown that random network coding with encryption and forward error-correction can help achieve provably good overall security and reliability performance.
