Welcome to the Post Quantum Lab

As quantum advancements accelerate, organizations must prepare to transition to "quantum-safe encryption" to protect their digital assets. The Post-Quantum Lab is our platform to provide you with the necessary tools and information to be ready on time.

Introduction

What is Post Quantum Cryptography ?

 

Post-quantum cryptography is a field of cryptography focused on developing encryption algorithms that remain secure against the advanced computational power of quantum computers, which can break widely used traditional methods like RSA and ECC.

To ensure your systems can resist quantum computer attacks, it is also required to run those quantum-proof algorithms on specific quantum resistant secure micro-controllers embedded in your devices. The chips will protect certificates and keys and secure the connexion protocols like TLS with post quantum cryptography instead of vulnerable traditional methods like RSA.

Be prepared for the Quantum Threat

To stay ahead of the quantum computing revolution, organizations need to begin implementing quantum-resistant encryption now. While large-scale quantum computers may still be years away, the security of today’s data is at risk, as attackers could harvest encrypted information now and decrypt it once quantum computers become more widely available.

Collaborate with Industry Standards

Work with organizations like NIST, which is actively developing standards for post-quantum cryptographic algorithms.

Quantum Resistant Hardware

A Quantum-Resistant Secure Microcontroller is an advanced embedded system designed to protect sensitive data and cryptographic operations from potential threats posed by quantum computing. These microcontrollers implement post-quantum cryptographic algorithms like KYBER CRYSTALS and DILITHIUM, ensuring resilience against quantum attacks that could compromise traditional encryption methods. By integrating also traditional robust security features such as secure boot, data encryption, tamper resistance, and key management, they provide a future-proof solution for applications in IoT, industrial systems, defense, and finance. With certifications like FIPS and Common Criteria, quantum-resistant secure microcontrollers offer unparalleled security for next-generation digital environments.

Post Quantum Root-of-Trust and PKI Services

SEALSQ has developed and deployed a new range of Trust Services leveraging post-quantum encryption (PQE) for real-world applications like digital signatures, encryption using PKI, secure communication channels (TLS), enhanced key exchanges, and email security (S/MIME). These services are based on finalized NIST standards, integrating hybrid signatures that combine conventional signatures with PQE algorithms in a single X.509 certificate. This ensures both resilience to quantum attacks and backward compatibility with existing systems.

SEALSQ's PKI platform, INeS, is now leveraging a PQE-based “Root of Trust” to generate certificates compliant with post-quantum standards. This foundational development supports SEALSQ's new portfolio of Trust Services and enhances the security of IoT projects, reinforcing its leadership in next-generation cybersecurity.
