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.
