复合窃听通道的保密结果

Secrecy Results for Compound Wiretap Channels

Igor Bjelakovic, Holger Boche, Jochen Sommerfeld

摘要:

我们推导出一个下限的复合窃听信道的信道状态信息的发送端的秘密容量相匹配的一般上限的一般复合窃听信道的秘密容量由梁等。从而建立一个完整的编码定理在这种情况下。我们实现了这一点,一个更强的保密标准和最大错误概率标准,并与解码器,是强大的对编码中的随机化的影响。这使我们无需解码随机化参数,这在该模型中通常是不可能的。此外,我们证明了一个下界的秘密容量的复合窃听信道没有信道状态信息,并推导出一个多字母的表达能力,在这种通信场景。

英文摘要:

We derive a lower bound on the secrecy capacity of the compound wiretap channel with channel state information at the transmitter which matches the general upper bound on the secrecy capacity of general compound wiretap channels given by Liang et al. and thus establishing a full coding theorem in this case. We achieve this with a stronger secrecy criterion and the maximum error probability criterion, and with a decoder that is robust against the effect of randomisation in the encoding. This relieves us from the need of decoding the randomisation parameter which is in general not possible within this model. Moreover we prove a lower bound on the secrecy capacity of the compound wiretap channel without channel state information and derive a multi-letter expression for the capacity in this communication scenario.
