通过允许路由器在转发之前合并接收到的分组，基于网络编码的应用程序容易受到可能的恶意污染攻击。现有的应对该问题的解决方案要么会引起代际污染攻击(在多代之间)，要么会遭受较高的计算/带宽开销。利用一种动态公钥技术，提出了一种新的用于网络编码的同态签名方案，在不更新初始密钥的情况下进行每一代认证。根据该思想，通过使用世代标识符对每个世代的秘密密钥进行加扰，并且可以使用针对分组所属的世代的加扰的秘密密钥来对每个分组进行快速签名。该方案不仅能有效抵抗代内污染攻击，还能有效防止代际污染攻击。此外，该方案的通信开销很小，并且与传输文件的大小无关。
By allowing routers to combine the received packets before forwarding them, network coding-based applications are susceptible to possible malicious pollution attacks. Existing solutions for counteracting this issue either incur inter-generation pollution attacks (among multiple generations) or suffer high computation/bandwidth overhead. Using a dynamic public key technique, we propose a novel homomorphic signature scheme for network coding for each generation authentication without updating the initial secret key used. As per this idea, the secret key is scrambled for each generation by using the generation identifier, and each packet can be fast signed using the scrambled secret key for the generation to which the packet belongs. The scheme not only can resist intra-generation pollution attacks effectively but also can efficiently prevent inter-generation pollution attacks. Further, the communication overhead of the scheme is small and independent of the size of the transmitting files.
