摘要
研究了网络编码中的防窃听问题,在实际的网络编码环境中,敌人通常拥有完整的窃听能力。提出一种新颖的防全局窃听者的编码算法,利用r个映射值来随机化原始数据包,这表明每个数据包只需要一个被加密的符号,对于中间节点没有其他附加的要求。与其他的方法相比,本方法的效率更高,并且计算复杂度也适中。
This paper studies the problem against eavesdropping attacks in network coding. In the practical network coding scenario, the adversary usually has full eavesdropping abilities. This paper brings forward a novel coding algorithm against overall eavesdroppers, uses r mapping values to randomize original data packets,which means that only one encrypted symbol is required for each data packet, there is no additional requirement to intermediate nodes. Compared with other methods,this scheme is more efficient and has appropriate computational complexity.
