摘要：

文章在已有的同态HASH签名基础上,为了解决网络编码传输过程中容易遭受污染攻击的问题,提出了一种新型的应用同态HASH函数的抗污染攻击系统,网络中的各个节点通过同步同态HASH函数的参数和原始消息分组的HASH值来对所收到的每个分组进行验证,只有通过验证的分组才会转发给下一个节点。该方案结合了针对源节点与目标节点端对端在线验证的安全ACK验证方案,从而能有效抵抗网络编码中的污染攻击。同时,为了有效降低网络编码中各节点的运算时间,文章提出了硬件加速的方法,利用FPGA开发板进行数据分组的验证以及编码操作,以提高系统的运行效率。该系统能够提高整体网络吞吐量,并确保被篡改的数据不会因为编码在整个网络中扩散,对于网络编码环境下的网络传输安全具有重要的作用。

Abstract:

We bring forward an anti-pollution-attack system with homomorphism hash function based on the homomorphic signature, which is a valid way to solve the problem that the transmission of network coding is likely to be pollution-attacked. In that way, every node in the network will verify passing groups by a sync parameter of hash function and hash of original message groups which is received in advance. Only the verified packet will be forwarded to the next node. We also use an ACK authentication solution between source node and destination node to resist pollution-attack in network coding. Also, we propose the hardware accelerated to reduce the computing time of each node. We use FPGA board to verification of data packet and encoding operation, which can improve the efficiency of the system. Another advantage of our system is to improve the transmission of network and it will discard polluted data groups automatically. It plays an important role in security transportation of network coding.
