Renesas Electronics and ESCRYPT Collaborate on Hardware/Software Security Solution for Automotive ECUs
Renesas Electronics Corp. and ESCRYPT GmbH, a system provider for embedded security, announced their collaboration on an integrated hardware and software platform solution that provides high-level security for protecting automotive electronic control units (ECUs).
The new joint hardware/software platform solution comprises Renesas’ RH850/P1x-C Series of automotive safety microcontrollers (MCUs) that combine on a single-chip: functional safety, security, and vehicle control network technologies, with ESCRYPT’s CycurHSM, a security software stack, to realize highly complex automotive security solutions.
The solution reduces development time and integrates security functions in safety-critical automotive ECU applications. Additionally, the solution serves as a stepping stone to achieve autonomous driving by accelerating the integration of safety and security functions.
In the autonomous-driving era, in-vehicle infotainment, vehicle-to-vehicle, and vehicle-to-infrastructure networks are expected to become mainstream. The connectivity between these networks allows systems to obtain information on road conditions and other factors that could impact the driving experience. It also requires robust security measures to ensure the systems are protected from unauthorized external access.
The RH850/P1x-C Series integrates a hardware security module with a co-processor supporting data encryption, authentication and random number generation to address these mission-critical security requirements in vehicle systems. CycurHSM is a security software stack that perfectly fits RH850/P1x-C MCUs and complements the security features in hardware with additional security services, e.g., secure boot, secure flashing, and debugging.
New use cases such as software updates Over The Air (OTA) or advanced driver assistance systems (ADAS) and the resulting in-vehicle communications require higher ECU protection levels against unauthorized or malicious access and manipulation. Therefore, in addition to protection through software, hardware security protection within the ECU has also become essential.
