带边信息的广义安全分布式信源编码

Generalized Secure Distributed Source Coding with Side Information

Somayeh Salimi, Mahmoud Salmasizadeh, Mohammad Reza Aref

摘要:

本文给出了带边信息的广义安全数据压缩的可达压缩-模糊率区域的新的内、外界,它们一般不匹配。在这种设置中,两个间谍,爱丽丝和查理打算通过有限容量的信道向鲍勃传输信息,以便他能够可靠地重建他们的观察结果。窃听者Eve在每个时刻都可以访问其中一个信道,并且对同一信道的源感兴趣。鲍勃和夏娃也有自己的观察结果,这些观察结果与爱丽丝和查理的观察结果相关联。在这个模型中,定义了两个歧义和压缩率相对于爱丽丝和查理的来源。此外,不同的特殊情况下,讨论的内部和外部边界匹配。我们的模型也涵盖了以前获得的结果。

英文摘要:

In this paper, new inner and outer bounds on the achievable compression-equivocation rate region for generalized secure data compression with side information are given that do not match in general. In this setup, two senders, Alice and Charlie intend to transmit information to Bob via channels with limited capacity so that he can reliably reconstruct their observations. The eavesdropper, Eve, has access to one of the channels at each instant and is interested in the source of the same channel at the time. Bob and Eve also have their own observations which are correlated with Alice's and Charlie's observations. In this model, two equivocation and compression rates are defined with respect to the sources of Alice and Charlie. Furthermore, different special cases are discussed where the inner and outer bounds match. Our model covers the previously obtained results as well.
