Symmetric Private Information Retrieval from MDS Coded Distributed Storage with Non-colluding and Colluding Servers
2019
IEEE Transactions on Information Theory
A user wants to retrieve a file from a database without revealing the identity of the file retrieved to the operator of the database (server), which is known as the problem of private information retrieval (PIR). If it is further required that the user obtains no information about the other files in the database, the concept of symmetric private information retrieval (SPIR) is introduced to guarantee privacy for both parties. For SPIR, the server(s) need to access some randomness independent of
