Location-Based Protocol for the Pairwise Authentication in the Networks without Infrastructure
In this paper, we consider security issues arising in the development of the wireless networks without infrastructure, with the rapidly changing composition of the elements of such a network The LEAP Initial Protection (LEAP-IP) protocol proposed, which closes the vulnerability of the LEAP at the network initialization stage. Advanced LEAP-IP protocol allows to resist attacks on the radio channel, physical attacks on the device, and is energy efficient, that is especially important for devices with a limited power resource. Also, a classification of self-organizing networks and some variants of using the proposed pairwise authentication protocol is presented
Pay as You Go: A Generic Crypto Tolling Architecture
The imminent pervasive adoption of vehicular communication, based on
dedicated short-range technology (ETSI ITS G5 or IEEE WAVE), 5G, or both, will
foster a richer service ecosystem for vehicular applications. The appearance of
new cryptography based solutions envisaging digital identity and currency
exchange are set to stem new approaches for existing and future challenges.
This paper presents a novel tolling architecture that harnesses the
availability of 5G C-V2X connectivity for open road tolling using smartphones,
IOTA as the digital currency and Hyperledger Indy for identity validation. An
experimental feasibility analysis is used to validate the proposed architecture
for secure, private and convenient electronic toll payment
Fast Authentication in Heterogeneous Wireless Networks
The growing diffusion of wireless devices is leading to an increasing demand for mobility and security. At the same time, most applications can only tolerate short breaks in the data flow, so that it is a challenge to find out mobility and authentication methods able to cope with these constraints. This paper aims to propose an authentication scheme which significantly shortens the authentication latency and that can be deployed in a variety of wireless environments ranging from common Wireless LANs (WLANs) to satellite-based access networks
The Meeting of Acquaintances: A Cost-efficient Authentication Scheme for Light-weight Objects with Transient Trust Level and Plurality Approach
Wireless sensor networks consist of a large number of distributed sensor
nodes so that potential risks are becoming more and more unpredictable. The new
entrants pose the potential risks when they move into the secure zone. To build
a door wall that provides safe and secured for the system, many recent research
works applied the initial authentication process. However, the majority of the
previous articles only focused on the Central Authority (CA) since this leads
to an increase in the computation cost and energy consumption for the specific
cases on the Internet of Things (IoT). Hence, in this article, we will lessen
the importance of these third parties through proposing an enhanced
authentication mechanism that includes key management and evaluation based on
the past interactions to assist the objects joining a secured area without any
nearby CA. We refer to a mobility dataset from CRAWDAD collected at the
University Politehnica of Bucharest and rebuild into a new random dataset
larger than the old one. The new one is an input for a simulated authenticating
algorithm to observe the communication cost and resource usage of devices. Our
proposal helps the authenticating flexible, being strict with unknown devices
into the secured zone. The threshold of maximum friends can modify based on the
optimization of the symmetric-key algorithm to diminish communication costs
(our experimental results compare to previous schemes less than 2000 bits) and
raise flexibility in resource-constrained environments.Comment: 27 page
