摘要:
 文中主要研究在安全网络编码技术中的抗污染问题。由于网络编码会在中间节点生成新的数据包，所以只要注入少量污染数据包就会造成污染扩张，从而造成网络性能下降。所以有必要在中间节点验证网络中是否发生污染攻击，但同时又要减少检验所带来的时间延迟。文中提出一种自适应抗污染攻击机制。该机制可以针对污染攻击严重情况来自适应调节中间节点的检测步骤，同时提高了运算效率并降低了验证时延。仿真结果表明，理论结果和实际计算吻合，自适应验证机制的时延相比传统验证机制较小。
Abstract:
 It mainly deals with pollution attacks in secure network coding in this paper. The new packet will be produced in the intermedi-ate nodes by employing network coding,so a small amount of pollution data packet could cause pollution expansion,which results in sub-stantially degraded performance for the network. Therefore,it is necessary to verify whether the intermediate nodes are in the pollution at-tack or not,and at the same time to reduce the time delay caused by security detection. An adaptive mechanism that can dynamically ad-just the authentication strategy of intermediate nodes is proposed so as to improve operational efficiency and decrease the time delay brought by verification. Simulation shows that theoretical results are in accordance with actual calculation,and the time delay of the adap-tive mechanism is less than that of traditional verification mechanism.
