Infineon and ETAS Collaborate on Enhanced Microcontroller Security

With the aim of enhancing security levels, performance, and functionality, ETAS and Infineon have joined forces to introduce a cutting-edge bundle. This collaboration is especially crucial in the automotive sector, where the demand for high-performance hardware and robust cybersecurity is escalating due to the shift towards software-defined vehicles and new E/E architectures.

Thomas Schneid, Senior Director Software, Partnership and Ecosystem Management at Infineon Technologies, emphasized the significance of the partnership, stating, “One of the strengths of our AURIX offering is the deep level of integration of our partners’ software. We are therefore deepening our partnership with ETAS even further to advance the development of software-defined vehicles.”

Rohan Pandit, Product Manager Onboard Security at ETAS, highlighted the benefits of integrating the latest version of ESCRYPT CycurHSM with the AURIX microcontroller family. He mentioned, “The integration will enable software-defined vehicles to meet increasing performance requirements while providing robust security."

The AURIX TC4x family aligns with the latest ISO/SAE 21434 cybersecurity standard, ensuring a robust security concept that eliminates performance bottlenecks and supports post-quantum cryptography. This family includes a Cybersecurity Real-time Module (CSRM) with dedicated memory and a Cybersecurity Satellite (CSS), which offers accelerators for cryptographic services to enhance throughput in conjunction with ESCRYPT CycurHSM 3.x.

Moreover, the support for virtualization allows the configuration of multiple virtual instances, enabling the concurrent operation of several applications. ESCRYPT CycurHSM 3.x leverages this feature to facilitate flexible boot-up sequences and independent dynamic updates for each virtual instance. Granular access control and the assignment of individual ASIL levels to each virtual instance enable diverse security applications.
