Bandwidth-optimized parallel private information retrieval [PDF]
Proceedings of the 7th International Conference on Security of Information and Networks, 2014 We present improved and parallel versions of Lipmaa’s computationally-private information retrieval (CPIR) protocol based on a additively-homomorphic cryptosystem.

Private Information Retrieval with Private Noisy Side Information [PDF]
IEEE Transactions on Information Theory, 2023 Consider Private Information Retrieval (PIR), where a client wants to retrieve one file out of $K$ files that are replicated in $N$ different servers and the client selection must remain private when up to $T$ servers may collude. Additionally, suppose that the client has noisy side information about each of the $K$ files, and the side information ...

Weakly-Private Information Retrieval [PDF]
2019 IEEE International Symposium on Information Theory (ISIT), 2019 Private information retrieval (PIR) protocols make it possible to retrieve a file from a database without disclosing any information about the identity of the file being retrieved. These protocols have been rigorously explored from an information-theoretic perspective in recent years.

On the Storage–Communication Trade-Off in Graph-Based X-Secure T-Private Linear Computation [PDF]
EntropyThe problem of graph-based X-secure T-private linear computation (GXSTPLC) is to allow a user to retrieve a linear combination of K messages from a set of N distributed servers that store the messages in a graph-based fashion, i.e., each message is ...

Proxy-Terms Based Query Obfuscation Technique for Private Web Search
IEEE Access, 2022 Search engines store users’ queries in a query log for performing personalized information retrieval. However, query logs cause privacy concerns and reveal a lot of information about individuals if used against them.

COMPUTATIONALLY EFFICIENT PRIVATE INFORMATION RETRIEVAL PROTOCOL [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2016 This paper describes a new computationally efficient private information retrieval protocol for one q-ary symbol retrieving. The main advantage of the proposed solution lies in a low computational complexity of information extraction procedure, as well ...
