Security analysis and evaluation of random linear network coding under wiretapping attack

This paper discussed the weak security of random linear network coding in wireless network in view of network coding weak security theory where the wiretapper can successfully obtain initial data and conditions threatening transmission security by decoding. The experiment results displayed, in wireless network, the relationship between decodes success probability of multi-node co-wiretapping, the decodes time of destination node and the node number in round and network, the number of data packet which source node sends every time, Galois field size and transmission radius of each node.
