HSM for Automotive (for Xilinx FPGA)

The HSM IP module is a Hardware Security Module for automotive applications. It is developed, validated and licensed by Silex Insight (partner of Xilinx) as an FPGA-based IP solution dedicated to the Xilinx Zynq UltraScale+ MPSoC platform.

As the connectivity of industrial systems, cars and their subsystems (like ADAS, autonomous driving, infotainment) is growing, so is the need for data integrity and system authentication. A very important aspect of this embedded security is a hardware security module (HSM), a security enclave that provides secure key management and cryptographic processing.

This HSM IP module removes the need for a dedicated HSM device and it incorporates 2 solutions:

  • The HSM hardware IP, to be implemented in programmable logic and ready to interface with the Zynq UltraScale+ processing system.
  • A software stack containing the HSM firmware, HSM driver code and an interface layer allowing integration into the AUTOSAR framework.


      • Secure key provisioning
      • Secure key storage
      • Secure counter
      • Flexible anti-tampering
      • Easy to integrate (AXI interface)
      • Cryptographic operations offload
        • PK engine
        • Symmetric engine
        • Random number generator
      • Flexible and scalable platform



  • AD/ADAS security
  • Infotainment security
  • Radar/LiDAR security


Configurable, scalable and flexible solution

The hardware security module can be scaled and configured to match any requirement, even for the most demanding applications. The size and performance of the solution can be adapted for a perfect application fit while leaving room in the FPGA for other critical applications.
