防窃听的弱安全网络编码
A Weakly Secure Network Coding against Wiretap Attack
摘要
Abstract
Network coding can achieve the theoretical multicast capacity of a network,and it is an important breakthrough in communica-tion field. The security is an important issue when network coding is used in practical network. In this paper,provide a VSWNC algo-rithm,which is weakly secure network coding algorithm against wiretap attack. Firstly,in VSWNC algorithm the source and the destina-tion share a random number generator. Secondly,in source node,a Vandermonde determinant P is generated using random number r in the random number generator and source message can be pre-coded using matrix P. Finally,user node can decode correctly using matrix P a-chieving from r. Using VSWNC in random network coding,can achieve the weakly secure condition at probability of one with sacrificing a small amount of capacity.关键词
