具有近视对手的网络编码

Network Coding with Myopic Adversaries

Sijie Li, Rawad Bitar, Sidharth Jaggi, Yihan Zhang

摘要:

我们考虑的问题,可靠的通信网络包含一个隐藏的{ \it近视}对手谁可以窃听一些$z_{ro}$链接,堵塞一些$z_{wo}$链接,并在一些$z_{rw}$链接。我们提供了第一个信息理论上的严格表征的最佳通信速率可能在所有可能的设置的元组$(z_{ro},z_{wo},z_{rw})$通过提供一种新的编码方案/分析的一个子集的参数制度。特别是,我们的消失的错误计划绕过网络单例界(这需要一个零错误恢复标准)在一定的参数制度的能力已经开放。作为一个直接的推论,我们也得到了相应的问题的能力,除了可靠的通信信息理论的保密性,对窃听是必需的。

英文摘要:

We consider the problem of reliable communication over a network containing a hidden {\it myopic} adversary who can eavesdrop on some $z_{ro}$ links, jam some $z_{wo}$ links, and do both on some $z_{rw}$ links. We provide the first information-theoretically tight characterization of the optimal rate of communication possible under all possible settings of the tuple $(z_{ro},z_{wo},z_{rw})$ by providing a novel coding scheme/analysis for a subset of parameter regimes. In particular, our vanishing-error schemes bypass the Network Singleton Bound (which requires a zero-error recovery criteria) in a certain parameter regime where the capacity had been heretofore open. As a direct corollary we also obtain the capacity of the corresponding problem where information-theoretic secrecy against eavesdropping is required in addition to reliable communication.
