本文考虑多个单播有线无噪声网络中,一个单一的源希望发送独立的消息到一组合法的目的地。主要目标是表征安全容量区域,其中交换的消息必须从具有无限计算能力但有限网络存在的被动外部窃听者获得安全。两个目的地的情况下的安全容量区域的特征在于,它被证明是一个函数的最小切割能力和边缘窃听窃听器窃听的数量。一个多项式时间的两阶段计划,然后设计了一般数量的目的地和它的可达到的安全速率区域。结果表明,两个目的地的情况下的安全容量的结果是不可逆的,也就是说,通过切换的源和目的地的角色,并通过反转的边缘的方向,安全容量区域的变化。
This paper considers multiple unicast wireline noiseless networks where a single source wishes to transmit independent messages to a set of legitimate destinations. The primal goal is to characterize the secure capacity region, where the exchanged messages have to be secured from a passive external eavesdropper that has unbounded computational capabilities, but limited network presence. The secure capacity region for the case of two destinations is characterized and it is shown to be a function of only the min-cut capacities and the number of edges the eavesdropper wiretaps. A polynomial-time two-phase scheme is then designed for a general number of destinations and its achievable secure rate region is derived. It is shown that the secure capacity result for the two destinations case is not reversible, that is, by switching the role of the source and destinations and by reversing the directions of the edges, the secure capacity region changes.
