SignQuantum Protects Digital Signatures from Quantum Threats
SignQuantum Releases First Post-Quantum Digital Signature Add-On for Future-Proof International Documents
SignQuantum, a post-quantum security provider and product of Qatar-based Quantum Software Solutions, introduced a breakthrough software add-on to safeguard digitally signed documents from quantum computing. This unique solution integrates with existing e-signature platforms, allowing organisations to transition to post-quantum security without overhauling their procedures. At the Doha launch ceremony, H.E. Sheikh Mansoor Bin Khalifa Al-Thani, founder and chairman of MBK Holding, SignQuantum CEO Nazmath Nazeer, and QANplatform co-founder and CTO Johann Polecsak were notable.
Quantum Risk to Digital Signatures
Quantum computing capabilities threaten digital signatures, which are critical to secure communication and transactional systems, immediately. Elliptic Curve Cryptography (ECC) and RSA are popular asymmetric cryptographic algorithms for digital signatures. These methods are threatened by Shor's algorithm, a quantum algorithm that factors large numbers and solves the discrete logarithm problem. Once quantum computers become strong enough, data signed today using these methods can be retroactively decoded and forged, proving this vulnerability goes beyond compromise.
Digital signature market to grow 40.9% to USD 118.88 billion by 2032 from USD 10.80 billion in 2025. This threat prompts NIST to standardise post-quantum cryptography (PQC), which uses algorithms that defy classical and quantum computer attacks. NIST advises public and private organisations to develop quantum-resistant cryptography by 2030 for data integrity and consumer trust. Because digital signature algorithms will become old and insecure after that year, system adjustments are needed.
Dual-Layer Post-Quantum Solution
The Post-Quantum Solution from SignQuantum addresses this global issue proactively. Incorporating NIST's top-recommended post-quantum cryptographic algorithms with QANplatform's quantum-resistant blockchain technology, developed by Qatari technology innovation and research lab Quantum Software Solutions under MBK Holding, is the solution's main innovation.
This two-layer method ensures signature authenticity and unchanging timing proof. Even when PQC is used for signature authenticity, quantum resistance is needed for timestamping, which determines event sequencing and prevents retroactive forging. In this case, QANplatform blockchain technology is vital. In 2024, Linux Foundation member QANplatform, one of the first 20 Post-Quantum Cryptography Alliance members, deployed quantum-resistant technology in one EU countries.
Technological Foundation and Smooth Integration
This integration is SignQuantum's technological foundation. PQC methods specified by NIST establish and validate digital signatures, ensuring their legitimacy. The hybrid blockchain architecture of QANplatform helps SignQuantum generate an immutable signature creation record and reduce long-term quantum risk. QANplatform resists classical and quantum computer assaults using cryptographic primitives including lattice-based cryptography and other quantum-resistant approaches.
QANplatform's virtual machine and consensus mechanism enable smart contracts in any programming language. Digital signatures may be utilised in more applications and produce complicated audit trails due to their versatility. The hybrid platform balances security, scalability, and energy efficiency by using proof-of-work and proof-of-stake consensus approaches. Managing high transaction volumes is crucial for QANplatform's growth and broad adoption.
The integration procedure is smooth and adds to current e-signature platforms without requiring major workflow modifications. QANplatform's SDK and APIs let developers easily add quantum-resistant blockchain functionalities. The QANplatform blockchain stores a cryptographic hash of the timestamp data and signed document, creating an immutable record that cannot be altered.
Industry Leaders Stress Quantum-Safe Future
Key players stressed this innovation's importance. SignQuantum “addresses a critical global challenge, paving the way for a secure post-quantum era across both the private and public sectors,” says MBK Holding founder and chairman Sheikh Mansoor Bin Khalifa Al-Thani. SignQuantum CEO Nazmath Nazeer highlighted the solution's seamless integration and 'fast-lane to quantum-safe security without disturbing existing procedures'.
QANplatform Co-Founder and CTO Johann Polecsak underlined the significance of merging a quantum-resistant blockchain with post-quantum digital signatures. He added that SignQuantum leverages the technology because post-quantum digital signatures lack impregnable confidence without a quantum-resistant blockchain platform that can mathematically establish authenticity. He further noted that the QANplatform can “not only safeguard, but also handle the large volume of digital transactions coming from SignQuantum”.
SignQuantum's scalable and interoperable solution for enterprises needing to future-proof their digital assets is a major step forward in document integrity in a rapidly evolving technological environment. NIST's projected deprecation of current digital signature methods beyond 2030 emphasises the need for reliable, quantum-resistant solutions to protect data integrity and customer trust.
