VaultysID-Q is an authentication solution that implements post-quantum cryptography to protect against current and future threats from quantum computing. The solution addresses the vulnerability of current cryptographic standards (RSA, ECC) to quantum computer attacks and the "harvest now, decrypt later" threat where attackers collect encrypted data today to decrypt it once quantum computers become available. The product combines decentralized identifiers (DID), post-quantum cryptography, peer-to-peer (P2P) protocol, and open source code. It implements NIST-standardized post-quantum algorithms including CRYSTALS-Kyber (FIPS 203) for key exchange, CRYSTALS-Dilithium (FIPS 204) for digital signatures, SPHINCS+ (FIPS 205) for hash-based security, and FALCON (FIPS 206) for compact signatures. VaultysID-Q provides passwordless authentication while maintaining compliance with GDPR and NIS2 regulations. The solution is designed to ensure long-term data protection and organizational resilience against technological disruptions from quantum computing advances. It offers a sovereign authentication approach that anticipates the obsolescence of classical cryptographic methods expected within the next 5-10 years as quantum computing capabilities advance.
