Introduction<\/h2>\n

As quantum computing advances, today's RSA\/ECC cryptographic systems face the threat of being broken. Post-quantum cryptography (PQC) has become a forward-looking area of investment in automotive cybersecurity.<\/p>\n

1. Why Should the Automotive Industry Care About PQC?<\/h2>\n
    \n
  1. Quantum computing could break existing RSA\/ECC encryption, putting vehicle communications, cryptographic keys and OTA signature security at risk.<\/li>\n
  2. The \"harvest now, decrypt later\" threat: attackers collect encrypted data today and break it in bulk once quantum computers mature.<\/li>\n
  3. Vehicles have long lifecycles (10\u201315 years), so provisions must be made well in advance to address future threats.<\/li>\n<\/ol>\n

    2. ISO 21434 and PQC<\/h2>\n

    The draft of the new edition of ISO 21434 already incorporates a migration plan for quantum-resistant algorithms (such as CRYSTALS-Kyber), placing higher computing-power demands on in-vehicle HSMs.<\/p>\n

    3. What PQC Demands of Automotive Chips<\/h2>\n

    PQC (such as CRYSTALS-Kyber) is computationally demanding, requiring more powerful in-vehicle HSMs. Mainstream automotive-grade chips have already begun to support PQC.<\/p>\n

    4. A Recommended Dual-Track Strategy<\/h2>\n
      \n
    1. Today: use China's national cryptographic algorithms (SM2\/SM3\/SM4) to meet current compliance requirements.<\/li>\n
    2. Tomorrow: reserve PQC capability to address quantum threats.<\/li>\n
    3. Establish a dual-track approach of \"national cryptography + quantum resistance\".<\/li>\n<\/ol>\n

      5. Implementation Recommendations<\/h2>\n
        \n
      1. Adopt a hybrid-encryption transition strategy (traditional algorithms running in parallel with PQC).<\/li>\n
      2. Reserve PQC hardware acceleration or software-upgradable support at the chip level.<\/li>\n
      3. Track the requirements for PQC migration in the new edition of ISO 21434.<\/li>\n<\/ol>\n

        Conclusion<\/h2>\n

        Post-quantum cryptography is not a distant future; it is a direction automotive cybersecurity must prepare for now. Moving early is the only way to stay secure and competitive through technological change.<\/p>\n
