Automotive security

Description

High expenses at car manufacturers for fixing software issues by costly recalls are driving the desire to use mobile communication channels to remotely execute software updates over the air (SOTA). Infineon’s OPTIGA™ TPM (Trusted Platform Module) is offering enhanced security mechanisms for the protection of a SOTA system. The demo shows a backend server, which provides a software update securely to a Telemetric ECU. The Telemetric ECU installs the software update in a target ECU using the Infineon Aurix™ controller.

Challenge

Remote Software Update is an innovate trend in the automotive industry to dynamically and efficiently react to security threats and bugs during the lifetime of a vehicle. The SOTA mechanism requires a high level of security to prevent threats and malicious usage of the update mechanism

Infineon Solution

The demo shows the security certified OPTIGA™ TPM which offers besides cryptographic operations a tamper resistant key store for high sensible credentials, and thereby enables not only protection of sensible external interfaces of the car, but also the vehicle supply chain. Infineon OPTIGA™ TPM are standardized security chips with generic security functionalities, that provide optimized cryptographic functions for SOTA based on both the TPM 1.2. and TPM 2.0 standard specifications.

Applications

› Secured Software Update Over The Air (SOTA) for automotive

› Secured communication between automotive ECUs

› Protected transfer of confidential data and software updates
