为合成DNA存储设计私有信息检索方案，兼顾隐私与可行性。
Private Information Retrieval for Large-Scale DNA-Based Data Storage
- 提出两种适配双服务器PIR协议的DNA存储方法
- 在隐私、效率与生物可行性间实现平衡
- 揭示信息论隐私在DNA系统中的权衡机制
我们研究了合成DNA数据存储中的私有信息检索（PIR）。尽管PIR在数字数据库中已有深入研究，但将其扩展至DNA数据库面临独特的挑战，源于生化查询机制及其复杂性。本文提出两种将双服务器PIR协议适配于DNA存储的方法，在隐私性、效率和可行性之间取得平衡。这些方法展示了信息论隐私权衡如何在DNA存储系统中体现。
原文摘要 · Abstract (English)
We investigate Private Information Retrieval (PIR) in the context of synthetic DNA-based data storage. While PIR is a well-studied primitive for digital databases, extending it to DNA-based databases presents unique challenges arising from biochemical query mechanisms and their complexity. We propose two approaches for adapting two-server PIR protocols to DNA-based storage, balancing privacy, efficiency, and feasibility. These approaches illustrate how information-theoretic privacy trade-offs manifest in DNA-based storage systems.
