AbstractGeneral-purpose computing on graphics processing units (GPGPU) has recently
gained considerable attention in various domains such as bioinformatics,
databases and distributed computing. GPGPU is based on using the GPU as a
co-processor accelerator to offload computationally-intensive tasks from the
CPU. This study starts from the observation that a number of GPU features (such
as overlapping communication and computation, short lived buffer reuse, and
harnessing multi-GPU systems) can be abstracted and reused across different
GPGPU applications.Efficient and Spontaneous Privacy-Preserving Protocol for Secure Vehicular Communications.

AbstractThis paper introduces an efficient and spontaneous privacy-preserving
protocol for vehicular ad-hoc networks based on revocable ring signature. The
proposed protocol has three appealing characteristics: First, it offers
conditional privacy-preservation: while a receiver can verify that a message
issuer is an authorized participant in the system only a trusted authority can
reveal the true identity of a message sender. Second, it is spontaneous: safety
messages can be authenticated locally, without support from the roadside units
or contacting other vehicles.
