SEALSQ, WISeKey, and Hedera: An Alliance for Quantum Security AllinCrypto November 17, 2025
The demand for secure, future-proof digital infrastructure is becoming more urgent as top tech firms develop faster, more powerful GPUs. Could crypto networks like Hedera help combat future threats?
SEALSQ x WISeKey have been collaborating with Hedera Hashgraph to shape the next generation of quantum-resistant identity and cybersecurity systems.
Their partnership is not only advancing the state of digital security but also paving the way for governments to indirectly utilize Hedera’s distributed ledger technology as part of long-term modernization plans.
Quantum-Safe Identity on a Public Ledger
SEALSQ and WISeKey are recognized for their work in semiconductors, digital identity, and public infrastructure. The firms have expanded into post-quantum cryptography, leading to the development of next-generation chips capable of withstanding quantum-level attacks.
By connecting these quantum-safe systems with Hedera’s distributed ledger network, they enable identity verification, device authentication, and critical data to be logged on a fast, tamper-proof public ledger.
Hedera’s consensus service is also able to create a durable and immutable audit trail that integrates seamlessly with WISeKey and SEALSQ’s hardware.
As of November 14, SEALSQ announced plans to focus on new Quantum-Resistant Root of Trust (QR-RoT) devices to further enhance its post-quantum solutions. These chips will store and generate cryptographic keys built to withstand quantum-level decryption methods, possibly interacting with Hedera to timestamp and validate actions.
Hedera is effectively becoming a security layer of post-quantum tech, which is still in its early days.
From SEALSQ on Post Quantum Root of Trust:
Built as an extension of SEALSQ’s INES platform, the U.S. Post-Quantum Root plans to support secure device onboarding, scalable credential management, and remote lifecycle operations.
Starting November 21, organizations will be able to generate Post-Quantum Certificates and device identities compliant with CNSA 2.0, mitigating supply- chain vulnerabilities and preparing for forthcoming federal Post-Quantum Cryptography (“PQC”) mandates.
How Governments Could Indirectly Adopt Hedera as a Security Layer
Many governments already use or approve WISeKey’s identity systems for passports, ID programs, smart city infrastructures, or defense-related digital security solutions.
As SEALSQ and WISeKey transition toward quantum-resistant solutions built on top of Hedera, the public sector could end up relying on Hedera’s technology indirectly in the future.
Governments may not need to deploy blockchain themselves, but instead, they could come into contact with Hedera’s DLT indirectly as an embedded component of new cybersecurity and identity solutions. An example would be those with SEALSQ and WISeKey.
This indirect adoption model is significant because it allows governments to reach quantum resilience without requiring major changes to existing digital infrastructures.
SEALSQ and WISeKey’s use of Hedera signals a broader shift in how institutions will secure their digital environments in the coming years.
Through partnerships, Hedera is emerging as a security layer for quantum-safe solutions that many investors will see as a surprise.
