Post-Quantum Cryptography for Automotive – Impact Assessment
The 5G Automotive Association (5GAA) and GSMA are pleased to release their new Technical Report “Post-Quantum Cryptography for Automotive – Impact Assessment, a new report examining the potential impact of quantum computing on the security of connected vehicles and automotive communications.
As advances in quantum computing continue, widely used cryptographic methods that underpin today’s digital communications may become vulnerable. This publication assesses the implications of this emerging threat for the automotive sector and explores key considerations for transitioning to post-quantum cryptography across both direct V2X communications and network communications interfaces.
The report analyses how post-quantum cryptography could affect connected vehicle systems, including impacts on computational performance, latency, message size, network efficiency, and long-term vehicle support. It also addresses industry-wide challenges such as legacy vehicle fleets, supply chain coordination, standardisation efforts, and regulatory alignment.
The publication highlights the importance of crypto-agility for future vehicle platforms, the need to address the legacy fleet challenge, and the value of a coordinated industry approach to support a gradual transition towards quantum-resilient automotive communication systems.
Read the report to learn more about the quantum threat to connected vehicles and the automotive industry’s roadmap towards post-quantum security.
