Abstract

In this paper, we introduce new codes for the private information retrieval (PIR). The conventional Tian-Sun-Chen (TSC) scheme achieves PIR capacity under the perfect privacy conditions with the minimum message length. Based on the TSC scheme, weakly PIR (WPIR) schemes have been developed to benefit download costs by relaxing privacy. We show that the proposed scheme has lower download cost than the TSC scheme in the weak privacy setting. While our scheme is not capacity-achieving under perfect privacy, it has smaller message sizes compared with the TSC scheme.

针对不完全隐私的新私人信息检索代码

本文介绍了用于私人信息检索（PIR）的新编码。传统的田舜臣（TSC）方案在完美隐私条件下以最小的信息长度实现了 PIR 容量。在 TSC 方案的基础上，开发了弱 PIR（WPIR）方案，通过放宽隐私条件来降低下载成本。我们的研究表明，在弱隐私设置下，我们提出的方案比 TSC 方案的下载成本更低。虽然我们的方案在完美隐私条件下无法实现容量，但与 TSC 方案相比，它的信息量更小。
