Quantum Secured Blockchain

Our Quantum Secured Blockchain (QSB) is engineered to create a blockchain network resilient against potential threats posed by Cryptographically Relevant Quantum Computers (CRQC). The design of QSB integrates three key elements of cutting-edge quantum-resistant technology:

  • Quantum Cryptography: At the forefront is Quantum Key Distribution (QKD) technology, which ensures secure communication channels between blockchain nodes.
  • Post-Quantum Cryptography (PQC): This component is crucial for the generation of robust private and public keys, along with secure digital signatures, ensuring the integrity and authenticity of transactions.
  • Quantum Random Number Generators (QRNG): These generators are essential for producing high-quality randomness, providing the blockchain with an essential layer of unpredictability and security.

Together, these technologies fortify the QSB, making it a pioneering solution in the realm of blockchain security against the emerging quantum computing era. Read about it here. You can also download its whitepaper.

post-Quantum Key Distribution

To support the development of our Quantum Secured Blockchain and other systems where quantum-resistant cryptography matters, we have developed, designed, and manufactured a patent-pending hardware device known as pQKD (post-Quantum Key Distribution). This device serves as a QKD system emulator and exceeds the latest Post-Quantum Cryptography standards recognized by NIST in terms of security.

The pQKD device boasts several key features:

  • ETSI QKD Protocol Compatibility: It is fully compatible with ETSI QKD protocols, specifically ETSI 004 and ETSI 0014. This ensures that a pair of pQKD devices can seamlessly replace actual QKD devices that implement these protocols.
  • Versatile Applications: The pQKD is versatile and can be used for secure key exchanges across various platforms, including routers, network encryptors, VPNs, SASE implementations, and other security systems.
  • Quantum Entropy Generation: It incorporates a QRNG (Quantum Random Number Generator) chip to generate genuine quantum entropy. Currently, the device uses ID Quantique’s ‘Quantis’ QRNG, the most compact quantum entropy chip available commercially.

While the pQKD does not offer the ultimate security level of real QKD, it provides a robust post-quantum key establishment mechanism (KEM) and an out-of-band communication channel for secure key exchange. Read about it here. The product brochure is available here.  


Quantum Cryptography Migration System

 The Quantum Cryptography Migration System (QCMS) is a suite of products and services designed to enable our clients to adopt Quantum Cryptography without incurring the high costs associated with QKD devices and dedicated fiber optics infrastructure. A critical component of QCMS involves installing preliminary Key Distribution devices (pQKD), and making necessary adjustments to other infrastructure elements, such as network encryptors, VPN systems, or Key Management Systems. Once all components are functioning seamlessly and security is thoroughly validated, the pQKD devices are replaced with full-fledged QKD systems to provide the highest level of security. A key advantage of this approach is the ‘cost-curve,’ which is significantly less steep than that of traditional migration methods. For more details, please refer to our service description.

Quantum Source of Entropy

Random number generators (RNGs) are a crucial component in the construction of cryptographic algorithms, playing an indispensable role in the security of cryptosystems for decades. However, traditional software-based solutions, known as Pseudo-Random Number Generators (PRNGs), cannot guarantee true unpredictability as a source of randomness. In contrast, True Random Number Generators (TRNGs), which derive randomness from various physical processes such as thermal or electrical noise, offer a more genuine form of randomness. Nonetheless, assessing the quality of random sequences generated by TRNGs can be challenging, leading to questions about their reliability.

A key measure of unpredictability in this context is entropy. High entropy in a random source is essential for achieving a truly uniform distribution of unpredictable values.

To address these challenges, we offer high-quality, off-line quantum entropy sources (QRNG devices) and web-based API services that feature multiple sources of quantum entropy. These solutions provide a higher level of randomness and security for cryptographic applications. See our devices and QRNG API services.

Post-Quantum Algorithms

There is a natural competition of ideas between quantum cryptography based on physical security and post-quantum cryptography based on advanced mathematical theories. While we strongly believe in the necessity for cybersecurity markets to adopt truly unbreakable cryptography, currently only guaranteed by quantum cryptography, we also support the transition to more robust algorithmic approaches offered by post-quantum cryptography. We are eagerly anticipating the NIST announcement of post-quantum cryptographic standards expected in mid-2024.

Additionally, we recognize that some cryptographic operations, such as signatures, cannot be implemented using quantum cryptography at this time. This conviction has driven us to implement key post-quantum algorithms in our products. Specifically, we have incorporated the CRYSTALS-KYBER Key Exchange algorithm, which relies on the hardness of solving the learning-with-errors (LWE) problems for high-dimensional lattices, into our pQKD devices. We have also integrated the CRYSTALS-Dilithium Digital Signature Algorithm into our QSB – Quantum Secured Blockchains. You can find more information about our work in post-quantum cryptography here

Cryptology Knowledge Graph

While developing our company’s vision for the future, we have observed that there is a significant lack of common knowledge about Quantum Cryptography. It is also unclear to many how Quantum Cryptography is positioned within the broader field of cryptology, which is a scientific discipline primarily focused on the study of cryptosystems. This discipline encompasses classical and post-quantum cryptography as well.

One of our defined goals is to establish an advanced Knowledge Graph and Ontology of Cryptology, with a particular emphasis on Quantum Cryptography. To achieve this, we have partnered with Metaphacts and will leverage their collaborative knowledge modeling and knowledge generation system to create the Cryptology Knowledge Graph. A substantial portion of this Knowledge Graph will be made available to the public free of charge. Visit our Quantum Cryptography knowledge graph here.

Consulting Services

The development of the Quantum Secured Blockchain concept has enabled our team to accumulate a substantial amount of knowledge and expertise spanning classical, post-quantum, and quantum cryptography, as well as modern security systems. We provide consulting services that can facilitate a seamless transition from current cryptographic solutions to quantum-secure alternatives, applicable to both traditional cybersecurity systems and blockchains.

Novel Quantum Communication protocols for Blockchain

Quantum Information science in general and Quantum Cryptography in particular offer promising methods that potentially could be used not only to enhance blockchains security but also to improve fundamental pillars on which they stay, like consensus mechanisms or smart-contracts. We are analyzing promising existing protocols, like CKA — Conference Key Agreement and are working on new ones. We believe that some iconic quantum phenomena like entanglement offer a possibility to make Blockchains faster, more resilient and better adapted to the changes in digital technology. However, we also proposed a conceptual scheme that enhances consensus protocol assuming only the use of Quantum Key Distribution techniques which are commercially available today (See our papers section).
