编码器带有因果状态信息的任意变化窃听信道上的强保密通信
Strong secrecy communication of arbitrarily varying wiretap channels with causal state information at the encoder
摘要
Abstract
To achieve reliable and secure communication over a channel in presence of a jammer and an eavesdropper,in which the encoder observed the jamming signal before transmitting each input symbol,a coding scheme was proposed,and the fundamental limits of the communication system was studied.The proposed coding scheme encoded each mes-sage using the observed jamming signal and was constructed as a code for reliable and secure communication over com-pound channels.Then,a set of random permutations over the codewords was used and the compound channel code was transformed into a code that could achieve reliable and secure communication over channels against arbitrarily varying jamming signals.A lower bound of the strong secrecy communication rate has been established.By analyzing the code over channels whose main channel is severely less noisy than the wiretap channel,the strong secrecy capacity of the channel is established and the proposed coding scheme is the optimal scheme.关键词
