摘要

我们考虑一个语义密码系统，在这个系统中我们只保护源的语义信息。在编码率、密钥率、语义信息泄漏率、信源重构失真和语义失真之间进行了最优权衡。结果表明，一个小尺寸的高效密钥足以保护语义信息。

Protecting Semantic Information Using An Efficient Secret Key

We consider a semantic cipher system, in which we protect only the semantic information of the source. The optimal tradeoff is characterized among the coding rate, the secret key rate, the semantic information leakage rate, the source reconstruction distortion, and the semantic distortion. It is shown that an efficient key with a small size suffices to protect the semantic information.
