An electronic control unit whose main function is to safely and reliably forward and transmit data between multiple networks of a vehicle.

Note: 1: Automotive Gateway can exchange information between functional domains that enjoy communication data through isolation between different networks and conversion between different communication protocols.

Note 2: The automobile gateway is also called the central gateway.

For example: OPTIGA? TPM SLI 9670？ It is a security enhanced trusted platform module (TPM), which is suitable for automotive applications based on tamper-proof microcontrollers with advanced security technology. As a complete ready-to-use solution, it has been brushed with security coding firmware, which conforms to the latest Trusted Computing Organization (TCG) 2.0 specification, so it can provide rich security functions.

This scheme can manage keys, authentication, signature function (signature/verification), encryption/decryption and security records, and also provide unique security time characteristics.

Typical security applications that OPTIGATPM SLI 9670 can realize through networked gateways include car entertainment, black box and OBD-2 recording, central key management, door control and braking, use-based insurance and various forms of commercial services, such as function activation. SLI 9670 conforms to AEC-Q 100 automobile standard, and has passed the general standard EAL4+ safety certification.
