The US Department of Transportation (USDOT) issued a proposed rule on January 12, 2017
to mandate vehicle-to-vehicle safety communications in light vehicles in the US …

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 …

This survey reviews the two most prominent group-oriented anonymous signature schemes
and analyzes the existing approaches for their problem: balancing anonymity against …

We introduce the notion of a dynamic accumulator. An accumulator scheme allows one to
hash a large set of inputs into one short value, such that there is a short proof that a given …

In this paper, we first identify some unique design requirements in the aspects of security
and privacy preservation for communications between different communication devices in …

This paper provides theoretical foundations for the group signature primitive. We introduce
strong, formal definitions for the core requirements of anonymity and traceability. We then …

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

We propose a dynamic accumulator scheme from bilinear pairings and use it to construct an
identity-based (ID-based) ring signature scheme with constant-size signatures and to …

Recently, a first step toward establishing foundations for group signatures was taken [5], with
a treatment of the case where the group is static. However the bulk of existing practical …
