A new level of cyber-threat 

Existing public-key cryptography is based on the difficulty of factoring and calculating elliptic curve discrete logarithms. Quantum systems can develop unbelievable calculation power, and will thus be able to decrypt widely used asymmetric security protocols, such as the commonly used RSA or elliptical curve algorithms that protect billions of IoT devices today. It is mandatory to start working on post-quantum cryptography before current cryptosystems become obsolete !

Quantum Computers

Quantum computers are machines that use the properties of quantum physics to store data and perform computations. This can be extremely advantageous for certain tasks where they could vastly outperform even our best supercomputers.
Classical computers, which include smartphones and laptops, encode information in binary “bits” that can either be 0s or 1s. In a quantum computer, the basic unit of memory is a quantum bit or qbit. 
For instance, eight bits is enough for a classical computer to represent any number between 0 and 255. But eight qubits are enough for a quantum computer to represent every number between 0 and 255 at the same time. A few hundred entangled qubits would be enough to represent more numbers than there are atoms in the universe…

The nature of Quantum Threat

We are entering a new era in which the quantum computer will replace in some cases “classical” computers and will be able to solve, within reasonable time, issues that were known to be unsolvable.
 In 1994, Peter Shor published an algorithm able to factorize a big integer into two prime numbers in polynomial time making the assumption of the existence of a quantum computer. This algorithm, not denied until now, is just waiting for the machine able to execute it. 
Fully error-corrected quantum computers will become available and the threat level for current protocols will vary. Yet some widely used asymmetric security protocols are potentially vulnerable to quantum computing: In 2019, researchers published an article in which they explained how a powerful quantum computer could break RSA algorithm in 8 hours.

The NIST Initiative

In April 2016, a NIST report highlighted the risk of quantum technology rendering widely used algorithms like RSA insecure by 2030. To address this, NIST launched a standardization process in December 2016, focusing on quantum-safe public-key cryptography, including digital signatures and key encapsulation mechanisms.

In August 2024, the National Institute of Standards and Technology (NIST) finalized its selection of quantum-resistant algorithms to safeguard against future quantum computing threats. The primary algorithms standardized are CRYSTALS-Kyber for key encapsulation mechanisms and CRYSTALS-Dilithium for digital signatures, both chosen for their robust security and performance. Additionally, NIST standardized the FALCON and SPHINCS+ digital signature schemes to provide diverse cryptographic solutions.

SEALSQ collaborates with academic and industry partners to develop cryptographic systems that are resilient to quantum attacks while maintaining compatibility with existing protocols. This proactive approach ensures the protection of sensitive information as quantum technologies evolve.

QUASARS Project

Following the NIST’s initiative to select the best Quantum-Resistant Algorithms, SEAL SQ has launched The QUASARS project. The aim is to build a post-quantum Root-of-Trust and Hardware Security Module able to run the new algorithms that will be selected by the NIST initiative, and still compliant with all other security requirements from the French ANSSI and Common Criteria EAL5+ label. The final platform will be the new RISC V SEAL SQ Platform, but the team has already taken steps to run two of the Crystals Algorithms (Kyber and Dilithium) appointed by the NIST on the existing MS 6003 secure hardware platform.

Challenges

Post-quantum algorithm technology still needs to solve a few key challenges to become scalable and efficient from an economic standpoint. 
In particular, the integration of post-quantum cryptosystems on microcontrollers raises some questions and uncertainties such as: 
  • Lack of security proofs for some existing schemes
  • Lack of side-channel attacks studies and countermeasures (especially with deep learning approach)
  • Sizes of manipulated data much bigger than those on the cryptosystems in current use
The mission of SEAL SQ’s Quantum Innovation team is to develop robust solutions, integrating specific countermeasures against side channel and deep learning attacks.
