IAV quantumSAR

IAV quantumSAR is planned as an AUTOSAR Cryptodriver with a collection of post-quantum cryptographic algorithms for microcontroller presented by IAV GmbH. The post-quantum cryptographic algorithms are based on the PQClean repository, which is a clean collection of the NIST post-quantum project. IAV quantumSAR implements these algorithms to use them for automotive microcontrollers in an AUTOSAR Classic environment. The goal is to have a collection of various cryptographic algorithms for future automotive cybersecurity projects preparing for the upcoming computing power of quantum computers.

Security Note

There was no security risk analysis like TARA or similar carried out for IAV quantumSAR. The post-quantum cryptographic algorithms itself were evaluated by NIST.

Content

The base of IAV quantumSAR is the PQCleanAutomotive repository. It includes the following post-quantum cryptographic algorithms:

  • CRYSTALS-KYBER
  • CRYSTALS-DILITHIUM
  • SPHINCS+
  • FALCON

Implementation

For the integration of IAV quantumSAR, the file Crypto.c contains an example of the use of the CRYSTALS-KYBER, CRYSTALS-DILITHIUM and SPHINCS+ algorithm.

In the SPHINCS+ algorithm, dynamic arrays had to be replaced by static arrays in various functions for the microcontroller implementation.

AUTOSAR

IAV quantumSAR should support the AUTOSAR Version R22-11.

MISRA

IAV quantumSAR and the post-quantum cryptographic algorithms are checked with the 2012 version of MISRA. Not all MISRA findings could be resolved. An explanation has been written in the relevant places.
