The origin of the COVID-19 pandemic has given overture to redirection, as well as
innovation to many digital technologies. Even after the progression of vaccination efforts …

We introduce the SPIRAL family of single-server private information retrieval (PIR) protocols.
SPIRAL relies on a composition of two lattice-based homomorphic encryption schemes: the …

The recent outbreak of COVID-19 has taken the world by surprise, forcing lockdowns and
straining public health care systems. COVID-19 is known to be a highly infectious virus, and …

It is known that fully homomorphic encryption (FHE) can be used to build efficient (labeled)
Private Set Intersection protocols in the unbalanced setting, where one of the sets is much …

The COVID-19 Pandemic has punched a devastating blow on the majority of the world's
population. Millions of people have been infected while hundreds of thousands have died of …

The COVID-19 pandemic created a noticeable challenge to the cryptographic community
with the development of contact tracing applications. The media reported a dispute between …

We address the problem of multiparty private set intersection against a malicious adversary.
First, we show that when one can assume no collusion amongst corrupted parties then there …

Abstract Boyle et al.(TCC 2019) proposed a new approach for secure computation in the
preprocessing model building on function secret sharing (FSS), where a gate g is evaluated …

Abstract Private Set Intersection Cardinality (PSI-CA) allows two parties, each holding a set
of items, to learn the size of the intersection of those sets without revealing any additional …

An unbalanced private set intersection cardinality (PSI-CA) protocol is a protocol to securely
get the intersection cardinality of two sets X and Y without disclosing anything else, in which …
