Advanced encryption algorithms for automotive communications.

Connectivity is essential in today’s vehicles. In such a connected environment, ensuring secure communication between vehicles, infrastructure, servers, and external entities is of utmost importance. Transport layer security (TLS) is a cryptographic protocol that has now become fundamental to establishing secure connections in the automotive industry.

Based on the TLS protocol, AutoCrypt® TLS utilizes a mix of the latest and most advanced cryptographic and key exchange algorithms to ensure that data and messages are transmitted safely in all types of automotive connections – including telematics, ADAS, EV charging ports, and IVI services.
