Efficient Private Information Retrieval Using Secure Hardware
Existing crypto-based Private Information Retrieval (PIR) schemes are either limited in the set of queries they can perform, or have prohibitively large performance overheads in making query comparisons. On the other hand, most previous tamper-resistant hardware schemes can support more general queries and have lower performance overheads, but need to trust that the query program will not leak ...
متن کاملSecure Coprocessor-based Private Information Retrieval without Periodical Preprocessing
Early works on Private Information Retrieval (PIR) focused on minimizing the necessary communication overhead. They seemed to achieve this goal but at the expense of query response time. To mitigate this weakness, protocols with secure coprocessors were introduced. They achieve optimal communication complexity and better online processing complexity. Unfortunately, all secure coprocessor-based ...
متن کاملReducing Retrieval Time in Automated Storage and Retrieval System with a Gravitational Conveyor Based on Multi-Agent Systems
The main objective of this study is to reduce the retrieval time of a list of products by choosing the best combination of storage and retrieval rules at any time. This is why we start by implementing some storage rules in an Automated Storage/Retrieval System (Automated Storage and Retrieval System: AS/RS) fitted with a gravity conveyor while some of these rules are dedicated to storage and ot...
متن کاملSecure Distributed Storage and Retrieval
In his well-known Information Dispersal Algorithm paper, Rabin showed a way to distribute information in n pieces among n servers in such a way that recovery of the information is possible in the presence of up to t inactive servers. An enhanced mechanism to enable construction in the presence of malicious faults, which can intentionally modify their pieces of the information, was later present...
متن کاملMultiround Private Information Retrieval: Capacity and Storage Overhead
The capacity has recently been characterized for the private information retrieval (PIR) problem as well as several of its variants. In every case it is assumed that all the queries are generated by the user simultaneously. Here we consider multiround PIR, where the queries in each round are allowed to depend on the answers received in previous rounds. We show that the capacity of multiround PI...
