Overview

32-bit AURIX™: A holistic security architecture with embedded Hardware Security Modules (HSM)

The AURIX™ 32-bit microcontroller family with its embedded Hardware Security Module (HSM) is a perfect fit for automotive applications, where specific security functionalities are indispensable. Typical examples of such applications are   immobilizer,  tuning protection, or secure on-board communication. Infineon offers a scalable portfolio of compatible AURIX™ devices with embedded HSM as well as matching software packages and support services.

AURIX™ Hardware Security Module

Highly flexible and programmable AURIX™ HSM solutions

HSM: A secure computing platform and anchor of trust thanks to separated logical protection domain that is based on:

  • Crypto and algorithm agility via software to support customer-specific solutions powered by a 32-bit CPU
  • AIS31-compliant True Random Number Generator (TRNG) with high random entropy over lifetime
  • State-of-the-art AES-128 hardware accelerator matching performance for automotive protocols
  • State-of-the-art PKC ECC 256 hardware accelerator for asymmetric encryption (only AURIX™ TC3xx HSM)
  • State-of-the-art HASH SHA2-256 hardware accelerator for hashing  (only AURIX™ TC3xx HSM)
  • Secured key storage provided by a separate HSM-SFLASH portion. Alternative secure key storage feasible in dedicated HSM-PFLASH sections. 
  • Safety documentation, such as a safety manual and safety analysis summary report, can be made available for dedicated PRO-SIL™ products (NDA may be required)

Secure Hardware Extension (SHE +)

The SHE+ driver controls the hardware security peripheral in the HSM domain and interacts with the TriCore™ host core. SHE+ offers the AUTOSAR CRY interface to integrate the HSM security features into an automotive application including interface to AUTOSAR, and communication from TriCore™ to HSM.

SHE+ can be added to existing MCAL driver packages and is configured with the Tresos Studio. This is an Eclipse-based tool for the configuration of AUTOSAR software modules and vice versa, key storage functionality, and security peripheral drivers.


SHE+ can offer the following functionality:

  • Symmetric data encryption/decryption
  • MAC generation/verification
  • Safe MAC verification
  • Random number management
  • Secure boot
  • Debug access for development
  • Asymmetric encryption/decryption (optional)

Customer benefits of AURIX™ security solutions

HSM (Hardware Security Module) provides a secure computing platform, consisting of a 32-bit CPU, special access-protected memory for storing the cryptographic key and unique subscriber identifiers, a hardware accelerator for the state-of-the-art AES-128 encryption that can be operated in different modes and specific hardware for generation of random numbers. It provides a secure platform separate from the rest of the microcontroller by a firewall, thereby creating a trusted execution environment. AURIX™ HSM fulfills SHE HIS and Evita Medium standards and provides some additional functionalities. AURIX™ security solutions are backward compatible to security SHE HIS implementations in previous TriCore™-based microcontroller families.

Customized secure OEM or Tier 1 crypto apps can be processed within trusted HSM execution environment and therefore allow independent HSM-specific SW code review in reference to the huge application host SW from multiple parties. AURIX™ microcontrollers address both functional safety as well as IT security requirements, making sure those are properly integrated and not conflicting with one another.
