Kolmogorov复杂性框架下的信息披露

Information disclosure in the framework of Kolmogorov complexity

Nikolay Vereshchagin

摘要:

我们考虑由两个开放信道$1\rightarrow 2$和$1\rightarrow 3$连接的三个节点$1, 2, 3$组成的网络。存在于节点1中的信息由四个字符串$x,y,z,w$组成。节点$2, 3$分别知道$x,w$和需要知道$y,z$。我们希望在信道上安排信息的传输,使得节点$2$和$3$都知道它们需要什么,并且信息的公开尽可能少。信息泄露是指通过信道传输的字符串中关于$x,y,z,w$(或关于$x,w$)的信息量。我们还感兴趣的是,是否有可能最大限度地减少信息的披露,同时最大限度地减少通过渠道传输的单词的长度。

英文摘要:

We consider the network consisting of three nodes $1, 2, 3$ connected by two open channels $1\rightarrow 2$ and $1\rightarrow 3$. The information present in the node 1 consists of four strings $x,y,z,w$. The nodes $2, 3$ know $x,w$ and need to know $y,z$, respectively. We want to arrange transmission of information over the channels so that both nodes $2$ and $3$ learn what they need and the disclosure of information is as small as possible. By information disclosure we mean the amount of information in the strings transmitted through channels about $x,y,z,w$ (or about $x,w$). We are also interested in whether it is possible to minimize the disclosure of information and simultaneously minimize the length of words transferred through the channels.
