一种新的分布式源加密框架
New Distributed Source Encryption Framework
摘要:
提出并研究了基于公钥密码体制的分布式安全信源编码。该密码系统包括Santoso和Oohama提出的使用后加密压缩的具有相关密钥的分布式加密源的保密放大问题。在本文中,我们提出了另一种新的安全标准,通常是更严格的比常用的安全标准,这是基于明文和密文之间的互信息的上界。在此准则下,我们建立了相关信源安全传输的充分必要条件。
英文摘要:
We pose and investigate the distributed secure source coding based on the common key cryptosystem. This cryptosystem includes the secrecy amplification problem for distributed encrypted sources with correlated keys using post-encryption-compression, which was posed investigated by Santoso and Oohama. In this paper we propose another new security criterion which is generally more strict compared to the commonly used security criterion which is based on the upper-bound of mutual information between the plaintext and the ciphertext. Under this criterion, we establish the necessary and sufficient condition for the secure transmission of correlated sources.
