IoT data markets in public and private institutions have become increasingly relevant in
recent years because of their potential to improve data availability and unlock new business …

Background: With increased specialization of health care services and high levels of patient
mobility, accessing health care services across multiple hospitals or clinics has become very …

In this work, we initially study the necessary properties and security requirements of Ring
Confidential Transaction (RingCT) protocol deployed in the popular anonymous …

Recent work, including ZKBoo, ZKB++, and Ligero, has developed efficient non-interactive
zero-knowledge proofs of knowledge (NIZKPoKs) for Boolean circuits based on symmetric …

This article is a position paper on the current security issues in Vehicular Ad hoc Networks
(VANETs). VANETs face many interesting research challenges in multiple areas, from …

We construct a short group signature scheme. Signatures in our scheme are approximately
the size of a standard RSA signature with the same security. Security of our group signature …

We propose a new and efficient signature scheme that is provably secure in the plain model.
The security of our scheme is based on a discrete-logarithm-based assumption put forth by …

Abstract We introduce Attribute-Based Signatures (ABS), a versatile primitive that allows a
party to sign a message with fine-grained control over identifying information. In ABS, a …

An accumulator is a function that hashes a set of inputs into a short, constant-size string
while preserving the ability to efficiently prove the inclusion of a specific input element in the …

Group signatures have recently become important for enabling privacy-preserving
attestation in projects such as Microsoft's ngscb effort (formerly Palladium). Revocation is …
