Designing a secure permissionless distributed ledger (blockchain) that performs on par with
centralized payment processors, such as Visa, is a challenging task. Most existing …

Protecting accounts from credential stuffing attacks remains burdensome due to an
asymmetry of knowledge: attackers have wide-scale access to billions of stolen usernames …

Password authentication is the dominant form of access control for the Web and mobile

An oblivious PRF, or OPRF, is a protocol between a client and a server, where the server
has a key k for a secure pseudorandom function F, and the client has an input x for the …

Abstract Partially Oblivious Pseudorandom Functions (POPRFs) are 2-party protocols that
allow a client to learn pseudorandom function (PRF) evaluations on inputs of its choice from …

In this article, we propose SPADE, an encrypted data deduplication scheme that resists
compromised key servers and frees users from the key management problem. Specifically …

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

PPSS is a central primitive introduced by Bagherzandi et al.[2] which allows a user to store a
secret among n servers such that the user can later reconstruct the secret with the sole …
