Protecting Your Digital Identity Against Future Quantum Computers
Smart Banner Hub is the first email signature platform to implement NIST-approved post-quantum cryptography, years ahead of the 2035 federal mandate. Your Maximum Security signatures are protected by the same ML-DSA (CRYSTALS-Dilithium) standard selected to secure U.S. government systems.

Every RSA and elliptic curve signature in use today relies on mathematical problems that classical computers cannot solve efficiently. Quantum computers running Shor's algorithm will render these protections obsolete—regardless of key size.
The National Institute of Standards and Technology (NIST) spent eight years evaluating quantum-resistant alternatives, finalizing three post-quantum cryptographic standards in August 2024. ML-DSA (formerly CRYSTALS-Dilithium), based on lattice cryptography, emerged as the primary standard for digital signatures.
The U.S. federal government has mandated full migration to quantum-safe cryptography by 2035, with legacy algorithms (RSA, ECC) to be phased out by 2030.
A quantum algorithm that can efficiently factor large numbers and solve discrete logarithm problems—breaking RSA and elliptic curve cryptography that protects most of today's digital communications.
Adversaries are already storing encrypted data today to decrypt when quantum computers become available. Data encrypted with current methods may be compromised retroactively.
U.S. government systems must complete quantum-safe migration by 2035. Legacy cryptographic algorithms will be deprecated by 2030. The clock is ticking.
NIST-approved post-quantum cryptography, available now
NIST FIPS 204 Standard
Module-Lattice-Based Digital Signature Algorithm. Based on the hardness of the Module Learning With Errors (MLWE) problem—a mathematical challenge believed to be resistant to both classical and quantum attacks. This is the primary post-quantum signature standard selected by NIST.
Ed25519 + ML-DSA
Smart Banner Hub uses both classical (Ed25519) and post-quantum (ML-DSA) signatures simultaneously. This provides defense in depth: if one algorithm is compromised, the other still provides protection. This is the approach recommended by NIST during the transition period.
Quantum-Resistant
Unlike SHA-2, SHA-3 is based on the Keccak sponge construction and provides additional resistance against potential quantum attacks. Used for all cryptographic hashing in Maximum Security signatures.
Memory-Hard KDF
Argon2id is resistant to GPU attacks and provides defense against both side-channel and brute-force attacks. The memory-hard nature makes it resistant to optimization attempts including those from quantum computers.
The security landscape is changing
NIST finalizes three post-quantum cryptographic standards, including ML-DSA (FIPS 204) for digital signatures.
Smart Banner Hub becomes the first email signature platform to deploy NIST-approved post-quantum cryptography in production.
U.S. federal government deadline to phase out legacy cryptographic algorithms (RSA, ECC) from government systems.
Full migration to quantum-safe cryptography required across all U.S. federal systems. Smart Banner Hub customers are protected years ahead of this deadline.
When large-scale quantum computers arrive, Smart Banner Hub Maximum Security signatures remain protected while traditional cryptography fails.
