Cloud computing is emerging as a new computing paradigm in the healthcare sector
besides other business domains. Large numbers of health organizations have started …

Vehicular ad hoc networks (VANETs) have recently received significant attention in
improving traffic safety and efficiency. However, communication trust and user privacy still …

In this paper, we compare the performance of descriptors computed for local interest
regions, as, for example, extracted by the Harris-Affine detector [Mikolajczyk, K and Schmid …

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 …

A credential system is a system in which users can obtain credentials from organizations
and demonstrate possession of these credentials. Such a system is anonymous when …

The fifth-generation (5G) mobile communication technology with higher capacity and data
rate, ultra-low device to device (D2D) latency, and massive device connectivity will greatly …

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 …

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 …

This paper describes the direct anonymous attestation scheme (DAA). This scheme was
adopted by the Trusted Computing Group (TCG) as the method for remote authentication of …
