Oblivious transfer (OT) protocol is an essential tool in cryptography that provides a wide
range of applications such as secure multi-party computation, private information retrieval …

Blockchain-based distributed storage enables users to share data without the help of a
centralized service provider. Decentralization eliminates traditional data loss brought by …

We study an adaptive variant of oblivious transfer in which a sender has N messages, of
which a receiver can adaptively choose to receive k one-after-the-other, in such a way that …

In recent years, oblivious pseudorandom functions (OPRFs) have become a ubiquitous
primitive used in cryptographic protocols and privacy-preserving technologies. The growing …

A secure set intersection protocol between sender S and receiver R on respective inputs X
and Y st| X|,| Y|≤ n, allows R to learn X∩ Y while S learns nothing about R's inputs. In other …

In an identity-based encryption (IBE) scheme, there is a key extraction protocol where a user
submits an identity string to a master authority who then returns the corresponding secret …

Communication in cache-coherent distributed shared memory (DSM) often requires
invalidating (or writing back) cached copies of a memory block, incurring high overheads …

Traditional voting and bidding systems largely rely on paperwork and human resources
throughout the voting process, which can incur high costs in terms of both time and money …

We present a highly efficient cryptographic protocol to protect user passwords against server
compromise by distributing the capability to verify passwords over multiple servers …

In an oblivious transfer (OT) protocol, a Sender with messages M 1,..., MN and a Receiver
with indices σ 1,..., σ k∈ 1, N interact in such a way that at the end the Receiver obtains …
