Cost amortization-based single-server private information retrieval method
Private information retrieval aims to protect users'query content and privacy,serving as an important extension of privacy protection in the field of information retrieval.A highly configurable,stateful,single-server private information retrieval scheme was designed based on the concept of cost amortization.Experiments conducted on a database containing 1 million 1 kB elements showed that this method delivered superior performance,being able to respond to client queries in less than 1 s,with the server's response data being increased by less than 3.6 times.It is noteworthy that the experimental analysis was based on a simple,unoptimized Rust implementation,suggesting that this method is particularly suitable for deployment environments involving a large number of clients.Experimental results indicate that this method holds significant potential in the field of private information retrieval and can provide an efficient and cost-effective solution for handling large-scale retrieval tasks.
