文摘

Network coding would enhance network throughput, improve network load balancing and buildup network robustness. In order to protect network against pollution attacks, homomorphic signature schemes for network coding are discussed. Based on the discussion and the SDH assumption, a secure signature scheme for network coding is proposed without random oracles. This scheme is efficient and supports the transmission of streaming data. Security analysis shows that the proposed scheme is secure against existential forgery under a choose message attack without random oracles.
