网络编码可以提高网络的吞吐量和可靠性。然而，它容易受到污染攻击和窃听攻击。此外，由于传统的安全网络编码（SNC）方案复杂度较高，许多方案不适用于资源受限的无线传感器网络（WSN）。提出了一种低复杂度的基于双素数的安全网络编码（DP-SNC）来防御窃听攻击。在DP-SNC中，首先通过双素数运算和随机变换构造DP序列，然后将编码过程分为两个阶段：利用DP序列的伪随机特性对源节点信息进行置乱，形成分片数据包;通过利用DP序列初始值中的第一个非零值构造的映射函数，这些数据分组被重新编码和发送。仿真结果表明，该方案能够保证原始信息的安全性，防御全局窃听者;并且计算复杂度低，加密容量小，空间开销小。
The network coding (NC) could improve the throughput and reliability. However, it is vulnerable for the pollution attack and the eavesdropping attack. What's more, due to the high complexity of traditional secure network coding (SNC) schemes, many of them are not suitable for resource-constrained wireless sensor network (WSN). In this paper, a low complexity secure network coding based on double primes (DP-SNC) is proposed to defense against the eavesdropping attack. In DP-SNC, DP-sequence is first constructed by double primes operation and randomized transform, and then the encoding process is divided into two phases: source node information is scrambled by using pseudo-random characteristic of DP-sequence, and fragmented data packets are formed; via the mapping function constructed Vandermonde code by using the first non-zero value in initial value of DP-sequence, these data packets are re-encoded and transmitted. The simulation results show that this scheme could guarantee the security of the original information, defense global eavesdropper; and lower computational complexity, smaller encryption capacity and lower space overhead.
