The most secure is in the form of personally identifying information (PII), which are credentials and keys that provide access to services or levels of capability. Logging or calibration data is typically the least secure. However, different levels of security are required. Most data is in use or in transit, and a small percentage that’s stored should be done so securely. The data comes in multiple forms: at rest, in use, and in motion.

Moreover, security systems to authenticate authorized drivers are getting more complex, while recording systems are being added to capture the last seconds before and after an accident to capture driving patterns, aiding law enforcement and insurance companies.Ī phenomenal growth in data has accompanied these new features, and with it a need to store them.

Take, for example, a rainfall-detection system that automatically activates the car’s windshield wipers when it senses precipitation on the windshield.Īnd then there are requirements for connectivity to secure servers to download mapping and positioning information as well as entertainment content (video and audio), and to manage software updates for onboard computer systems. Lighting and other environmental controls are increasing and becoming more automated.
Infotainment options and connections to onboard LCD monitors are growing, too. Clusters are being converted from mechanical to electronic displays along with the addition of head-up displays (HUDs).
The emission and powertrain control systems are more complex to manage hybrid propulsion.
The main reasons for these increases are the growing inclusion of driver-assistance features that include adaptive cruise control, cameras, object identification, and notification/crash avoidance. The amount of advanced electronics in autos is growing exponentially. The attack could also be the theft of sensitive data ranging from personal financial data to information that could be used to bring down the defenses of a vehicle causing unauthorized use. It could be by installing malware by modifying software stored in memory, or installing a sniffer device that modifies software or data in transit between memory and a host. Non-volatile memory and security features commonly offered in these devices will be the focus here, because they’re commonly targeted in attacks, either directly or indirectly. Vehicles that fall within this definition cover a wide range of types-from ground to air, from consumer to commercial. Internet of Vehicles, or IoV, is the term that describes this classification. In vehicles with autonomous driving-assistance system (ADAS) functionality, they could be also be considered connected artificial-intelligence edge devices. 1 Targeted IoT devices range from atmospheric sensors, remote payment systems, IP cameras, smart lighting systems, and home routers to connected vehicles, which is the main focus of this article.Ĭonnected vehicles are, in essence, connected IoT devices or edge computing platforms. These numbers don’t even include smartphones, tablets, laptops, or fixed line phones. In 2018, the overall number of connected devices worldwide was 17 billion, approximately half of which were Internet of Things (IoT) devices, according to market research firm IoT Analytics. Modern society is currently experiencing exponential growth of connected devices on public Internet Protocol (IP) networks.
