The network coding (NC) could improve the throughput and reliability. However, it is vulnerable for pollution attack eavesdropping attack. What's more, due to high complexity of traditional secure (SNC) schemes, many them are not suitable resource-constrained wireless sensor (WSN). In this paper, a low based on double primes (DP-SNC) proposed defense against DP-SNC, DP-sequence first constructed by operation randomized transform, then encoding process divided into two phases: source node information scrambled using pseudo-random characteristic DP-sequence, fragmented data packets formed; via mapping function Vandermonde code non-zero value in initial these re-encoded transmitted. simulation results show that scheme guarantee security original information, global eavesdropper; lower computational complexity, smaller encryption capacity space overhead.
