通过偏振的随机性和相关性提取,以及Slepian-Wolf编码和保密的应用

Randomness and dependencies extraction via polarization, with applications to Slepian-Wolf coding and secrecy

Emmanuel Abbe

摘要:

将单个源的极化现象推广到多个相关源的情况。除了提取源的随机性之外,极坐标变换还将原始的任意依赖关系变为极值依赖关系。基于这一现象,提出了解决Slepian-Wolf问题和秘密密钥生成的极化编码方案.特别地,实现保密容量的秘密密钥的构造和实现Slepian-Wolf容量区域的压缩方案以$O(n \log (n))$的复杂度获得。

英文摘要:

The polarization phenomenon for a single source is extended to a framework with multiple correlated sources. It is shown in addition to extracting the randomness of the source, the polar transforms takes the original arbitrary dependencies to extremal dependencies. Polar coding schemes for the Slepian-Wolf problem and for secret key generations are then proposed based on this phenomenon. In particular, constructions of secret keys achieving the secrecy capacity and compression schemes achieving the Slepian-Wolf capacity region are obtained with a complexity of $O(n \log (n))$.
