Doha, Qatar, August 5th, 2025, Chainwire
SignQuantum, a post-quantum security provider for critical documents, officially launched its post-quantum cryptography solution designed to safeguard digitally signed documents from looming cybersecurity threats posed by quantum computing.
SignQuantum introduces a software add-on that integrates with e-signature platforms, allowing organizations to transition into the post-quantum era without overhauling existing workflows. The core of its innovation solves two of the most pressing challenges of digital signatures: ensuring authenticity and securing immutable proof of timing. It leverages the U.S. National Institute of Standards and Technology’s (NIST) primary-recommended post-quantum algorithm, and the quantum-resistant blockchain technology of QANplatform.
“SignQuantum seamlessly integrates with popular e-signature platforms, offering organizations a fast-lane to quantum-safe security without disrupting existing workflows,” said Nazmath Nazeer, CEO of SignQuantum. “SignQuantum uniquely solves two key challenges: maintaining digital signature authenticity and securing proof of timing by utilizing NIST’s primary-recommended post-quantum algorithm and quantum-resistant blockchain technology from QANplatform.”
SignQuantum’s product launch took place in Doha, Qatar, with (above pictured from left to right) Johann Polecsak, Co-founder and CTO of QANplatform; H.E. Sheikh Mansoor Bin Khalifa Al-Thani, Founder and Chairman of MBK Holding; and Nazmath Nazeer, CEO of SignQuantum.
The digital signature industry is experiencing a meteoric rise—currently valued at $10.8 billion in 2025 and projected to soar to $118.9 billion by 2032, with a compound annual growth rate (CAGR) of 40.9%. This surge is fueled by increased digital transformation, growing regulatory compliance demands, and the widespread shift to remote-first operations.
Reliance on digital signatures is growing, but alongside vulnerabilities to quantum computing. Emerging quantum computers have the potential to compromise traditional cryptographic algorithms, allowing malicious actors to retroactively alter signed documents. Companies risk that documents signed today could be tampered with in the future—undermining legal and regulatory trust.
NIST has acknowledged this threat and is urging public and private institutions to begin adopting quantum-resistant cryptography before 2030. After that date, NIST will begin to deprecate current digital signature algorithms, meaning those algorithms will be considered insecure and will be unsupported. In turn, companies will be required to update their systems and processes to maintain data integrity and customer trust. SignQuantum’s technology addresses this through three core features:
- Seamless Integration, Zero Workflow Changes: SignQuantum integrates effortlessly with leading e-signature software and is customizable for any digital signature provider.
- NIST Post-Quantum Cryptography Standards: Both SignQuantum and its underlying quantum-resistant blockchain platform, QANplatform, utilize NIST’s primary-recommended post-quantum digital signature algorithm.
- Dual-Layer Security with Signature Authenticity + Immutable Timing: maintaining digital signature authenticity and securing proof of timing of digitally signed documents.
“Delistings of Root CAs (Certificate Authorities) prove the decline of trust in centralized entities acting as a single source of trust in the last decades,” said Johann Polecsak, Co-Founder and CTO of QANplatform. “Although blockchain is the tool for decentralized trust, it is the technology most affected by the threat of quantum computing. Post-quantum digital signature algorithms don’t provide unquestionable trust on their own, unless paired with a quantum-resistant blockchain platform capable of mathematically proving authenticity, which is why SignQuantum leverages our technology. QANplatform is capable of not only safeguarding, but also handling the large volume of digital transactions coming from SignQuantum.”
“We are incredibly proud to see Qatari innovation making strides on the global stage. SignQuantum addresses a critical global challenge, paving the way for a secure post-quantum era across both the private and public sectors,” said Sheikh Mansoor Bin Khalifa Al-Thani, Founder and Chairman of MBK Holding, and former director of information technology for The Council of The Qatar Ruling Family Affairs.
