SignQuantum Launches Quantum-Resistant Add-On for Digital Signatures

SignQuantum, a post-quantum security provider for critical documents, launched a quantum-resistant add-on designed to protect digitally signed documents from future threats posed by quantum computing [1]. The solution integrates with existing e-signature platforms, enabling organizations to adopt post-quantum security without overhauling current workflows. It addresses two critical challenges: ensuring the authenticity of digital signatures and securing immutable proof of timing. The technology leverages the U.S. National Institute of Standards and Technology’s (NIST) primary-recommended post-quantum algorithm and the quantum-resistant blockchain of QANplatform [1].

The product launch took place in Doha, Qatar, and was highlighted by the presence of key figures, including 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 [1]. Polecsak emphasized the importance of combining post-quantum digital signatures with quantum-resistant blockchain to establish trust in the face of quantum threats. Al-Thani praised Qatari innovation and highlighted the significance of the solution in securing a post-quantum future for both public and private sectors [1].

The digital signature market is currently valued at $10.8 billion and is projected to reach $118.9 billion by 2032, driven by digital transformation and regulatory demands [1]. However, as quantum computing advances, traditional cryptographic algorithms face increasing vulnerability. NIST has warned that existing algorithms will be phased out by 2030 and urged institutions to begin adoption of quantum-resistant solutions now [1]. SignQuantum’s offering aims to future-proof digital documents by integrating three core features: seamless integration with e-signature platforms, compliance with NIST post-quantum standards, and dual-layer security for authenticity and immutable timing [1].

SignQuantum is a product of Quantum Software Solutions, a Qatari technology innovation lab and a member of MBK Holding [1]. The company positions itself as a bridge to quantum-safe security, enabling businesses to maintain document integrity without disrupting current operations. The solution relies on QANplatform, a quantum-resistant blockchain platform that provides mathematical proof of authenticity and handles high-volume transactions [1]. QANplatform, a member of the Linux Foundation, was the first to deploy quantum-resistant technology in an EU country in 2024 [1].

The digital signature industry is at a pivotal juncture as it transitions to a quantum-safe future. With global investment in technology startups increasing, the adoption of quantum-resistant solutions is expected to gain momentum. SignQuantum’s launch marks a strategic step in this direction, offering a scalable and interoperable solution for enterprises seeking to protect long-term document integrity [1].
