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…

Timely Estimation Using Coded Quantized Samples

Ahmed Arafa, Karim Banawan, Karim G. Seddik +1

The effects of quantization and coding on the estimation quality of a Gauss-Markov, namely Ornstein-Uhlenbeck, process are considered. Samples are acquired from the process, quanti…

Semantic Private Information Retrieval

Sajani Vithana, Karim Banawan, Sennur Ulukus

We investigate the problem of semantic private information retrieval (semantic PIR). In semantic PIR, a user retrieves a message out of independent messages stored in repli…

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…
