Securing Real-Time Internet-of-Things

Modern embedded and cyber-physical systems are ubiquitous. A large number of critical cyber-physical systems have real-time requirements (e.g., avionics, automobiles, power grids, manufacturing systems, industrial control systems, etc.). Recent developments and new functionality requires real-time embedded devices to be connected to the Internet. This gives rise to the real-time Internet-of-things (RT-IoT) that promises a better user experience through stronger connectivity and efficient use of next-generation embedded devices. However RT- IoT are also increasingly becoming targets for cyber-attacks which is exacerbated by this increased connectivity. This paper gives an introduction to RT-IoT systems, an outlook of current approaches and possible research challenges towards secure RT- IoT frameworks

Hardware Security of the Controller Area Network (CAN Bus)

The CAN bus is a multi-master network messaging protocol that is a standard across the vehicular industry to provide intra-vehicular communications. Electronics Control Units within vehicles use this network to exchange critical information to operate the car. With the advent of the internet nearly three decades ago, and an increasingly inter-connected world, it is vital that the security of the CAN bus be addressed and built up to withstand physical and non-physical intrusions with malicious intent. Specifically, this paper looks at the concept of node identifiers and how they allow the strengths of the CAN bus to shine while also increasing the level of security provided at the data-link level

Driving with Sharks: Rethinking Connected Vehicles with Vehicle Cyber Security

In a public service announcement on March 17, 2016, the Federal Bureau of Investigation (FBI) jointly with the Department of Transportation and the National Highway Traffic Safety Administration, released a warning over the increasing vulnerability of motor vehicles to remote exploits . Engine shutdown, disable brakes and door locks are few examples of the possible vehicle cyber security attacks. Modern cars grow into a new target for cyberattacks as they become increasingly connected. While driving on the road, sharks (i.e., hackers) only need to be within communication range of your vehicle to attack it. However, in some cases, they can hack into it while they are miles away. In this article, we aim to illuminate the latest vehicle cyber security threats including malware attacks, On-Board Diagnostic (OBD) vulnerabilities, and auto mobile apps threats. We illustrate the In-Vehicle network architecture and demonstrate the latest defending mechanisms that are designed to mitigate such threats
