Quantum safe authenticated key exchange protocol for automotive application

  • In this work, we propose an instantiation of a quantumsafe security protocol for authenticated key establishment (AKE) with forward secrecy. As core primitives, we use Newhope and XMSS and avoid signatures in the key exchange to achieve better performance. Exemplary, the implemented protocol could be used to establish a secured and authentic communication channel between the electrical control unit (ECU) and a testing device for onboard diagnosis (OBD). To verify the feasibility, we implement an XMSSbased public key infrastructure (PKI) and the AKE protocol on the AURIX automotive embedded microcontroller platform. We provide a breakdown of cycle cost and communication overhead and demonstrate that a modern postquantum AKE can be executed efficiently on our target platform.
