In this paper, we propose a physical layer security scheme that exploits novel index modulation (IM) technique for coordinate interleaved orthogonal designs (CIOD). Utilizing the diversity gain of CIOD transmission, proposed scheme, named CIOD-IM, provides an improved spectral efficiency by means IM. order to provide satisfactory secrecy rate, design particular artificial noise matrix, which do...

Cellular vehicle-to-everything (V2X) communication is emerging as a feasible and cost-effective solution to support applications such vehicle platooning, blind spot detection, parking assistance, traffic management. To these features, an increasing number of sensors are being deployed along the road in form roadside objects. However, despite hype surrounding cellular V2X networks, practical rea...

Abstract Vehicular platoons are among the most advanced driving assistance systems that may generate considerable fuel savings and increase traffic efficiency. However, communication between vehicles in a platoon is always vulnerable to eavesdropping due broadcast nature of wireless channels. To address this issue, we investigate security issues from physical layer perspective for multi-hop veh...

Function-approximated images are suitable for transmission over the networks, because they can be scaled on the sidelines of various resolutions of network terminals with relatively small amount of information. In this work, we use the Fluency function-approximation method that utilizes the Fluency information theory. The theory can deal with images in scalable and high-precision. Transmitted i...

In recent years, vehicle communications technologies and wireless networking technology are continuous development, when we use wireless communications to exchange information data, traffic will be more secure and convenient than that of the past.We describe the problem that characterizes the privacy of VANETs and proposes a new anonymous key mechanism with a system architecture based on biline...

Plasma, a platform for secure multimedia applications, allows secure communications within public networks and is particularly suited for transmitting compound multimedia documents. Using Plasma, it is possible to negotiate the cryptographic protocols to be applied before starting the communication proper. This allows communications between domains using diierent security policies which, in add...

Joint Beamforming and Artificial Noise Design in Secure Millimeter-wave Communications with the Aid of Intelligent Reflecting Surfaces

We consider the problem of privacy (anonymity) and security in vehicular (V2V) communication, in particular securing routine safety messages. Traditional public key mechanisms are not appropriate for such applications because of the large number of safety messages that have to be transmitted by each vehicle, typically one message every 100−300ms. We first show that a recently proposed V2V commu...

This work proposes a Certification Authorities organization in order to achieve secure open communications. The report considers current international ongoing works as well as existing practices. Actually, our work tries to solve the present shortcomings when trying to organize a hierarchical CAs structure based on a naming hierarchy. The proposal focuses in the idea of having certification and...
