Fully Robust Federated Submodel Learning in a Distributed Storage System
Zhusheng Wang, Sennur Ulukus
We consider the federated submodel learning (FSL) problem in a distributed storage system. In the FSL framework, the full learning model at the server side is divided into multiple…
Private Information Retrieval and Its Applications: An Introduction, Open Problems, Future Directions
Sajani Vithana, Zhusheng Wang, Sennur Ulukus
Private information retrieval (PIR) is a privacy setting that allows a user to download a required message from a set of messages stored in a system of databases without revealing…
Digital Blind Box: Random Symmetric Private Information Retrieval
Zhusheng Wang, Sennur Ulukus
We introduce the problem of random symmetric private information retrieval (RSPIR). In canonical PIR, a user downloads a message out of messages from non-colluding and repl…
Communication Cost of Two-Database Symmetric Private Information Retrieval: A Conditional Disclosure of Multiple Secrets Perspective
Zhusheng Wang, Sennur Ulukus
We consider the total (upload plus download) communication cost of two-database symmetric private information retrieval (SPIR) through its relationship to conditional disclosure of…
Symmetric Private Information Retrieval with User-Side Common Randomness
Zhusheng Wang, Sennur Ulukus
We consider the problem of symmetric private information retrieval (SPIR) with user-side common randomness. In SPIR, a user retrieves a message out of messages from non-col…
Multi-Party Private Set Intersection: An Information-Theoretic Approach
Zhusheng Wang, Karim Banawan, Sennur Ulukus
We investigate the problem of multi-party private set intersection (MP-PSI). In MP-PSI, there are parties, each storing a data set over replicated and non…
Private Set Intersection: A Multi-Message Symmetric Private Information Retrieval Perspective
Zhusheng Wang, Karim Banawan, Sennur Ulukus
We study the problem of private set intersection (PSI). In this problem, there are two entities , for , each storing a set , whose elements are picked f…
