Quantum-Resistant Cryptography

The rise of quantum computing poses a significant threat to modern cryptographic systems that protect online communications and sensitive data, as they rely on cryptographic algorithms that are not quantum-resistant. Once quantum computers become powerful enough to execute Shor’s algorithm at scale, widely used asymmetric cryptographic algorithms—such as RSA, (EC)DSA, and (EC)DH—will become vulnerable, as quantum computers will be able to break them in a matter of seconds.

Post-Quantum Cryptography (PQC) refers to a new generation of asymmetric cryptographic algorithms designed to resist quantum attacks. Unlike traditional methods, PQC does not depend on quantum mechanics for key exchange but instead leverages complex mathematical problems that cannot be efficiently solved by quantum computers.

To address this global security challenge, NIST initiated a post-quantum cryptography standardization process in 2016, inviting candidates for evaluation. After several selection rounds, in August 2024, NIST finalized three post-quantum digital signature standards: CRYSTALS-Dilithium, FALCON, and SPHINCS+, marking a crucial step toward a quantum-resistant future.

The pioneer work of Blerify’s founding team on quantum-resistant cryptography and blockchain led to the development of the first implementation of a Quantum-Resistant EVM Blockchain, which was published by Nature's Scitific Reports Magazine and featured as a top 100 publication in 2023. At Blerify, we are implementing NIST-compliant PQC algorithms to safeguard digital identity and ensure cryptographic integrity against future quantum threats.
