Post-Quantum Cryptography in Logistics: IBM and NIST Push for Supply Chain Resilience

Quantum Threats Enter the Supply Chain Conversation

February 2020 marked a significant inflection point in cybersecurity discussions within the logistics sector. As quantum computing matured, concern intensified around the disruptive potential of quantum attacks on classical encryption methods — especially RSA and ECC, both foundational to digital trust in global trade and logistics.

Until recently, post-quantum cryptography (PQC) had remained largely within academic and cybersecurity circles. But following advances by Google, IBM, and Chinese researchers in demonstrating quantum supremacy and growing qubit stability, supply chain technology firms and third-party logistics (3PL) platforms began actively evaluating how to future-proof their cryptographic protocols.

IBM Leads the PQC Charge for Enterprise Infrastructure

On February 18, 2020, IBM announced that its IBM Z and LinuxONE mainframe platforms—widely used in financial services and global shipping—would begin supporting quantum-safe cryptography libraries, including lattice-based key encapsulation and hash-based signature schemes.

This development was notable for logistics because many large freight operators, customs systems, and global ERP platforms run on IBM Z mainframes. Adding PQC support meant enterprises could start experimenting with cryptographic agility—preparing to swap vulnerable algorithms for quantum-safe counterparts as standards emerge.

IBM also open-sourced its PQCrypto library on GitHub in early February, accelerating adoption and inviting contributions from partners in finance, logistics, and telecommunications.

NIST’s Standardization Process Draws Interest from Logistics Providers

The U.S. National Institute of Standards and Technology (NIST) had launched its PQC competition back in 2016 to select new encryption and digital signature algorithms resistant to quantum attacks. But by February 2020, the competition had narrowed to Round 3 finalists, attracting growing attention from sectors outside traditional cybersecurity.

Among the PQC finalists—such as Kyber, NTRU, SABER, and Dilithium—logistics tech providers like Descartes Systems Group and project44 began internal reviews to determine compatibility with their telemetry systems, IoT devices, and cross-border documentation platforms.

Security leaders in maritime logistics, including Maersk and Hapag-Lloyd, participated in workshops hosted by NIST affiliates to evaluate how quantum-safe cryptographic protocols could be implemented in EDI transmissions, smart containers, and IoT-based asset tracking systems.

Supply Chain Security at a Crossroads

Why the urgency? Global supply chains rely on asymmetric cryptography to secure a staggering range of processes:

• Digital customs declarations

• Blockchain-based shipping manifests

• GPS and satellite IoT sensor data

• Vehicle-to-vehicle (V2V) communication in autonomous fleets

• Smart contract execution in logistics marketplaces

Quantum computers, once reaching fault-tolerant capacity, could theoretically break RSA-2048 in hours. While that milestone may still be a decade away, the threat to encrypted data “harvested now, decrypted later” is real. Bad actors may already be collecting encrypted logistics data with the intent of breaking it once quantum hardware is ready.

This vulnerability is especially alarming in aerospace logistics and defense-related freight, where encryption is mission-critical.

February Industry Collaborations: PQC Awareness Grows

In Europe, February also saw the European Telecommunications Standards Institute (ETSI) Quantum-Safe Cryptography Working Group release its updated technical report on PQC migration paths—offering best practices for supply chain companies beginning their journey toward quantum resistance.

Meanwhile, in Japan, NTT and Mitsubishi Electric announced a joint study to assess quantum-safe encryption’s viability in industrial control systems used in logistics automation—highlighting Asia’s increasing commitment to PQC in logistics infrastructure.

Challenges to PQC Adoption in Logistics

Despite the momentum, significant barriers remain:

• Hardware Constraints: Many IoT sensors and embedded logistics devices lack the processing power to run resource-intensive PQC algorithms.

• Lack of Interoperability: PQC standards are still evolving. Logistics providers risk lock-in or incompatibility across international partners.

• Performance Trade-Offs: Some quantum-safe algorithms produce large keys or slower computation times, posing issues for real-time logistics networks.

• Awareness Gaps: Many supply chain operators are unaware of the looming quantum threat or assume they can wait until quantum computers are commercially viable.

Yet, as we saw in February 2020, more industry voices began to argue that PQC migration needs to begin now—not when it’s too late.

IBM and NIST Drive an Ecosystem Approach

IBM’s PQC push in February included partnerships with logistics software vendors to test integration with IBM Z platforms. The company encouraged logistics providers to adopt a “crypto-agility” mindset—designing systems that can quickly switch between encryption schemes as the threat landscape changes.

NIST, for its part, emphasized that standardization wouldn’t be enough. It launched collaborative working groups focused on implementation guidance, particularly for critical infrastructure sectors such as transportation and logistics.

Looking Ahead: A Call to Action

Industry analysts in February 2020 predicted that global PQC adoption in logistics would be gradual but inevitable. Gartner even listed “post-quantum security” as one of the top 10 strategic technology trends of the year.

More logistics operators now recognize that cryptographic agility must become part of their IT strategy. Quantum computing, though still in its infancy, has lit a fuse under the encryption status quo.

Conclusion

February 2020 was a turning point in the relationship between quantum computing and supply chain security. IBM’s support for post-quantum cryptography on enterprise systems—and the narrowing of NIST’s algorithm selection process—created a sense of urgency in logistics circles previously detached from quantum conversations.

While there is no immediate threat of quantum attacks today, the window to prepare is shrinking. Logistics operators who begin migrating to crypto-agile frameworks and testing post-quantum protocols now will be best positioned to maintain trust, security, and competitiveness in the era of quantum disruption.
