How Quantum Computers Will Affect Cars: A Deep Dive into Post-Quantum Cryptography in Automotive Security

Listen to this Post

Researchers from Volkswagen and ETAS have explored the impact of Post-Quantum Cryptography (PQC) on the automotive industry in their paper, “Impacts of Post-Quantum Cryptography on Automotive Security: A Case Study.” The study highlights critical automotive security functions vulnerable to quantum computing threats and suggests PQC algorithms to future-proof vehicles.

Affected Automotive Security Functions:

  1. Key Management System (KMS) – Quantum computers could break traditional encryption, necessitating quantum-resistant key management.
  2. Secure Boot – Firmware validation must adopt PQC to prevent tampering.
  3. Secure Diagnostic Access – Unauthorized access via quantum attacks could compromise vehicle diagnostics.
  4. Transport Layer Security (TLS) for V2X Communication – Quantum-safe TLS protocols are essential for secure vehicle-to-everything communication.

You Should Know: Practical Steps to Prepare for Post-Quantum Automotive Security

1. Quantum-Resistant Key Management

  • Use CRYSTALS-Kyber (a PQC algorithm) for key exchange: 
    openssl genpkey -algorithm kyber -out kyber_private.key
openssl pkey -in kyber_private.key -pubout -out kyber_public.key

2. Secure Boot with PQC Signatures

  • Implement CRYSTALS-Dilithium for firmware signatures: 
    openssl dgst -sha3-512 -sign dilithium_private.key -out firmware.sig firmware.bin

3. Quantum-Safe TLS for V2X

  • Configure OQS-OpenSSL for quantum-resistant TLS: 
    openssl s_server -cert quantum_cert.pem -key quantum_key.pem -tls1_3 -groups kyber768

4. Secure Diagnostic Access with PQC

  • Replace RSA with Falcon-512 for authentication: 
    falcon512-keygen -o falcon_private.key -O
falcon512-sign -k falcon_private.key -m diagnostic_request.bin -s diagnostic_signature.sig

What Undercode Say

The shift to post-quantum cryptography is inevitable, and the automotive industry must act now. Linux and Windows administrators should start testing PQC algorithms in lab environments. Below are additional commands to explore:

Linux Commands for PQC Testing:

 Install liboqs for quantum-safe crypto 
git clone https://github.com/open-quantum-safe/liboqs.git 
cd liboqs && mkdir build && cd build 
cmake .. && make && sudo make install

Test Kyber key exchange 
openssl s_client -groups kyber768 -connect example.com:443

Windows PowerShell for PQC Readiness:

 Check supported TLS ciphers (including PQC candidates) 
Get-TlsCipherSuite | Where-Object { $_.Name -like "OQS" }

Generate a Falcon key pair 
Import-Module PQCrypto 
New-FalconKeyPair -OutputPrivateKey "falcon_priv.key" -OutputPublicKey "falcon_pub.key"

Expected Output:

Quantum-resistant algorithms (Kyber, Dilithium, Falcon) must replace RSA/ECC in automotive systems. Start testing now to avoid future breaches.
