摘要
网络编码允许中间节点对数据包先编码再转发,提高了系统的鲁棒性并节约网络资源。实际应用中网络编码容易受到污染攻击,鉴于此,该文提出网络编码环境下无双线性对的无证书签密(NC-CLPFSC)。NC-CLPFSC通过同态哈希函数防御污染攻击,而且还避免了密钥托管和证书管理,同时降低了计算和通信成本。
Network coding allows the intermediate nodes to encode and forward the data packets,so it improves the system robustness and saves the network resources.Pollution attacks are inevitable for network coding in applications.In view of this,CertificateLess Pairing-Free SignCryption for Network Coding(NC-CLPFSC)is proposed.NC-CLPFSC uses the homomorphic Hash function to resist the pollution attacks;Moreover,it avoids the key escrow and certificate management,and it reduces the computation and communication cost.
