标题： A Framework of Distributed Source Encryption using Mutual Information Security Criterion and the Strong Converse Theorem

摘要： 我们重新研究了基于公共密钥密码系统的通用分布式安全源编码，该系统由Oohama和Santoso（ITW 2021）提出。 他们提出了分布式源加密的框架，并推导出了实现可靠和安全传输的必要和充分条件。 然而，指定在所提出的密码系统下实现可靠和安全传输的必要和充分条件的速率区域的界限，是基于一个自定义的非标准安全准则推导得出的。 在本文中，我们采用标准的安全准则，即标准互信息。 我们成功地基于这一安全准则建立了速率区域的界限。 信息谱方法和Birkhoff-von Neumann定理的一个变体在推导结果中起到了重要作用。 显示英文摘要

摘要： We reinvestigate the general distributed secure source coding based on the common key cryptosystem proposed by Oohama and Santoso (ITW 2021). They proposed a framework of distributed source encryption and derived the necessary and sufficient conditions to have reliable and secure transmission. However, the bounds of the rate region, which specifies both necessary and sufficient conditions to have reliable and secure transmission under the proposed cryptosystem, were derived based on a self-tailored non-standard} security criterion. In this paper we adopt the standard security criterion, i.e., standard mutual information. We successfully establish the bounds of the rate region based on this security criterion. Information spectrum method and a variant of Birkhoff-von Neumann theorem play an important role in deriving the result.
