Pain points

The global automotive cybersecurity market size is projected to grow from USD 1.9 billion in 2020 to USD 4.0 billion by 2025, at a CAGR of 16.5%, according to Markets and Markets. It analysed that increased use of electronics per vehicle and a growing number of connected cars, and reinforcement of mandates by regulatory bodies for vehicle data protection are some of the key factors that will drive the market for the automotive cybersecurity market.

- Connectivity issue in cellular networks

Digital car key solution aims to complement traditional methods while being robust enough to fully replace them. It allows individual owners to easily and confidently use their mobile devices to access vehicles. However, it isn’t likely to replace the physical keys any time soon. Since current digital key solutions require network connectivity for certain operations, the driver’s mobiles and vehicles should be connected to the network to receive and activate the key. Drivers often come across an accessibility issue when the vehicle is located in a basement or rural area where network connectivity is typically weak. We need a better digital key solution to overcome the risk of relying on a network connection for the user’s ultimate keyless access.

- External connection risks

The in-vehicle network is designed to operate in a closed environment, so security issues are unlikely to occur. However, as the number of external interfaces to the in-vehicle network increases, the probability of the occurrence of security issues increases. Connecting inexpensive commercial devices or continuous communication with external networks for autonomous vehicles exposes drivers to constant threats. Vehicles exposed to external threats are not only results in financial damage but can be directly related to life, so more attention is required.

- Mobile app authentication vulnerability

Manufacturers release their own mobile apps to facilitate communication with vehicles. As a result, we are always facing malicious threats through these apps. For example, in the case of a token-based authentication process, a hacker can remotely turn off the vehicle or issue an incorrect command. In particular, if unnecessary in-vehicle systems are operated and the battery of the electric vehicle is forcibly consumed, the vehicle may not move.
