摘要
Network coding is an effective method to optimize network throughput and improve routing reliability, and has been widely used in a decentralized Internet of Things system. However, the packet-mixing property of network coding renders transmission susceptible to pollution attacks, which may prevent the reconstruction of the original file. A homomorphic signature scheme is a powerful tool that enables network coding to combat pollution attacks. Although a series of homomorphic signature schemes already exists, no construction has been proposed to support both homomorphic network coding signatures and the certificateless characteristic. In this paper, we construct a certificateless linearly homomorphic signature scheme for network coding, thus avoiding the disadvantages of certificate management and key escrow problems. We then prove the security of the scheme in a random oracle model against an adaptively chosen dataset attack under two types of adversaries. Moreover, performance analysis results show that our scheme has a lower communication overhead and enjoys a comparable computation cost with related schemes.
