In this paper, we propose an efficient homomorphic message authentication code （MAC） scheme with discrete logarithm to detect and locate the malicious nodes. We also prove the security property of the scheme theoretically. Its effectiveness is demonstrated, and overhead is analyzed through extensive experiments.展开更多

文摘Network coding can improve network throughput in large, but it is vulnerable to the data pollution attacks. In this paper, we propose an efficient homomorphic message authentication code （MAC） scheme with discrete logarithm to detect and locate the malicious nodes. We also prove the security property of the scheme theoretically. Its effectiveness is demonstrated, and overhead is analyzed through extensive experiments.
