In the near future, beacon dissemination base stations will be deployed in shopping mall, supermarkets, stadiums, museums, and theatres to send advertisements offering services and products to the customers with mobile devices. Today, an example of this concept of business model is the Apple's iBeacon. Borrowing this concept from mobile computing, we envision a new opportunity for business modeling...
With expectation of widespread adoption of Connected Vehicles Technology (CVT), security within the vehicular networks has come under scrutiny. Owing to the nature of CVT applications, security flaws can result not only in loss of data or network function but also in fatal accidents. Security mechanisms that can account for privacy, authentication, integrity, and non-repudiation while having an acceptable...
In vehicular ad hoc networks (VANETs), vehicles communicate with each other and with roadside units (RSUs) in order to enhance road safety, improve traffic management and provide infotainment services. Along with the growth of VANETs, some challenges are emerging. Although there are many research work on VANETs, cheating attacks are still not well resolved such as selective message relaying attack,...
Cyber security concerns in the automotive industry have been constantly increasing as automobiles are more computerized and networked. Recent successful hacks of modern vehicles demonstrate the big security concerns for automotive systems. However it is still very hard and even impossible to predict what kinds of security issues will happen. In this paper, we present the automotive security concerns...
Security protocols built on strong cryptographic algorithms to defeat attempts of pattern analysis are popular nowadays, but these algorithms consume a lot of processor's efficiency. So, devices with limited processor capabilities need some modified protocols. Billions of such devices, known as ‘smart objects’ are used in IOT (Internet of things). IOT is an interconnection of a large number of smart...
We are proposing a layered and scalable WAVE (Wireless Access for Vehicular Environments) security structure for VANET (Vehicular Ad hoc Network) network. The scalability and variable message delivery are provided by using both asymmetric and symmetric encryption algorithm. The whole region is divided into different security domains and the security related load of each domain is distributed evenly...
The paper deals with the cryptographic design and experimental implementation of a scheme for (but not limited to) vehicular ad-hoc networks (VANETs). In contrast to existing solutions, our scheme does not need any complex infrastructure (like costly road-side units or special on-board devices) and is based just on users' smart-phones and Internet connection. We call this simplified concept SVANETs...
In the first part of this paper the operation mechanism of exchanging the data used in vehicles and equipment as well as the applied security measures have been presented. In the further part of the work, the identification method for the data in the network, for which the encoding system is not known, has been discussed. Subsequently, a suggestion of the decoding method for the network-derived data...
Vehicular networks are seen as the basis for the development of intelligent transportation systems. Therefore, and in order to take advantage of the benefits from these transportation systems, the development of standards that meet the specific characteristics of vehicular networks was required. The "Wireless Access in Vehicular Environments" (WAVE) was developed in order to fulfill this...
Plug-in Electric Vehicles (PEVs) are expected to be widely utilized in the near future if issues related to the availability of charging infrastructure are resolved and if PEVs are efficiently integrated with the smart grid. The Vehicle-to-Grid (V2G) system is an emerging technology that enables the communication and control between PEVs and the smart grid. This promising concept is designed to provide...
Vehicular Ad Hoc Network (VANET) are gaining more importance because they have opened new research fields by extending data networks connectivity to Vehicle to Vehicle where wired solutions are difficult to install. The networks which are deployed in the areas where the needed infrastructure is not feasible to install are Adhoc networks. Vehicular Ad hoc Network (VANETs), in which each vehicle (node)...
Most modern metropolitan cities have suffered from increasing traffic accidents and jams. Vehicular ad hoc network (VANET), consisting of information collecting, processing and transmitting units embedded in vehicles assisted by roadside infrastructures, has been proposed as one the most promising solution to problems introduced by the increasing number of vehicles in modern cities. To achieve the...
With intensive research and field operational tests over the intelligent transportation area and the advancements of information and communication technologies, intelligent transportation systems reach the stage of deployment. EU focuses on cooperative intelligent transportation systems and confirms the finalization of the first release of the standards, paving the way for deployment in the coming...
The International Standards Organization (ISO) and the European Telecommunications Standards Institute (ETSI) have defined a common ITS reference communications stack which have paved the way to new research lines in vehicular networks. Currently, most of the efforts have focused on the definition and testing of ITS applications operating over Internet Protocol version 6 (IPv6) communication technologies...
Vehicular ad hoc networks (VANETs) are advanced instances of mobile ad hoc networks with the aim of enhancing the safety and efficiency of road traffic. The basic idea is to allow arbitrary vehicles to broadcast ad hoc messages (e.g. Traffic accident notifications) to other vehicles and remind drivers to change their routes immediately or slow down to avoid dangers. However, some concerns on security...
In the near future, vehicles will establish a spontaneous connection over a wireless radio channel, coordinating actions and information. Security infrastructure is most important in such a hazardous scope of vehicles communication for coordinating actions and avoiding accidents on the roads. One of the first security issues that need to be established is authentication. Vehicle authentication with...
A Bus Driver (BD) controller design is presented in this investigation, where all of the hazard detection and protection required by FlexRay 3.0.1 are integrated and realized, including under-voltage (UV), bus failure, wake-up detection, etc. The required 4-state transition for FlexRay BD control is also carried out to coordinate the interfacing and signaling among the ECU (electronic control unit)...
Cooperative intelligent transport systems supporting secure vehicle to vehicle and vehicle to infrastructure communications, is becoming a very important topic. The aim of this paper is to share our experiences from implementing the ETSI Intelligent Transport System (ITS) SecuredMessage and sign/verify services on an existing ETSI ITS communication stack (ITSC). We have followed the new ETSI TS 103...
Location privacy remains an open issue in VANETs. Although, frequently pseudonym changing is commonly accepted as solution to protect privacy in VANETs, many studies have been shown its weakness to provide the required level of privacy protection. In this paper, we propose a practical pseudonym changing strategy, called Silence & Swap at Signalized Intersection (S2SI). S2SI consists of two...
Vehicular Ad-Hoc NETworks (VANETs), a pillar for the Internet of Vehicles, aim to improve road safety by preventing and reducing traffic accidents. While VANETs offer a great variety of safety and infotainment applications, there remain a number of security and privacy challenges, such as, user profiling and vehicle tracking, which, must be addressed. This paper contributes with a framework to address...
