Post-Quantum Identity Access Management

Identity access management (IAM) is the discipline of establishing who or what an actor is and controlling what that actor is permitted to reach. H33’s contribution to IAM is cryptographic: it lets an actor prove an identity or authorization claim without exposing the credential behind it — a supporting expression of the ZK Platform, which proves without revealing. It exists because the credentials IAM depends on — passwords, biometrics, session tokens — are exactly the material attackers want; the safest credential is one the server verifies but never sees. H33 supplies the proof-and-verification layer; it does not replace the directory, lifecycle, or authority decisions that surround it.

IAM Is the First Thing Quantum Computers Break

RSA and ECC underpin every identity access management system deployed today. Session tokens are RSA-signed. SAML assertions rely on RSA or ECC signatures. OAuth flows depend on TLS with classical key exchange. Certificate chains use RSA public keys. Active Directory trusts Kerberos tickets signed with symmetric keys derived from classical protocols.

Quantum computers running Shor's algorithm break all of it. RSA-2048 falls to a sufficiently large quantum computer in hours. ECC-256 is even more vulnerable -- it requires fewer logical qubits to break than RSA. Every session token, every SAML assertion, every OAuth access token, every certificate chain that uses classical cryptography becomes forgeable.

IAM is the highest-value target because it controls access to everything else. Compromise IAM and you compromise every system it protects. You do not need to attack individual services when you can forge the identity tokens that grant access to all of them. A single quantum break of your IAM layer is a full-scope breach.

The Harvest Now, Decrypt Later Problem

Nation-states are capturing IAM traffic today. Session tokens, authentication flows, credential exchanges, SAML assertions, OAuth token grants -- all of this network traffic is being archived by adversaries with the patience and storage to wait for quantum computers.

This is not a theoretical concern. The NSA and CISA have publicly warned about harvest-now-decrypt-later attacks. Intelligence agencies with petabytes of storage capacity intercept and archive encrypted sessions routinely. The data does not expire. A session token captured today will be just as decryptable in ten years when quantum computers reach sufficient scale.

If your IAM uses RSA or ECC, your users' identities are already at risk. Every authentication event, every password change, every MFA challenge, every single sign-on flow that traversed a network is potentially captured and waiting for decryption. The breach has already happened -- you just cannot see it yet.

Post-Quantum IAM with H33

Every authentication in H33 uses ML-DSA (Dilithium, FIPS 204) for digital signatures and ML-KEM (Kyber, FIPS 203) for key exchange. These are NIST-standardized post-quantum algorithms that resist both classical computers and quantum computers. Session tokens are Dilithium-signed -- quantum computers cannot forge them.

Biometric matching happens inside fully homomorphic encryption. Biometric templates are encrypted at enrollment using BFV lattice-based FHE. They are never decrypted. The matching algorithm computes an inner product on ciphertext and returns an encrypted match score. The server performs the authentication without ever seeing the biometric template. A breach of the authentication server exposes ciphertext indistinguishable from random noise.

Key exchange uses ML-KEM (Kyber) to establish session keys. Even if a quantum adversary captures the key exchange, they cannot derive the session key. Combined with Dilithium-signed session tokens, every component of the authentication flow is quantum-resistant. There is no classical cryptography in the critical path.

Every authentication operation is attested with a ZK-STARK proof that the server executed the protocol correctly without accessing plaintext. The proof is publicly verifiable. You do not need to trust the server -- you can verify it mathematically.

Where H33 Fits in Your Identity Stack

Reach for H33 when the authentication step itself must be quantum-resistant and privacy-preserving — encrypted biometric matching, credentials that are never decrypted server-side, or a proof of identity that a relying party can verify without seeing the secret. It is the strongest fit for high-value, high-volume, or regulated authentication where credential exposure is the core risk.

H33 is not a replacement for your directory, user lifecycle, SSO orchestration, or provisioning — those remain with your identity provider, and H33 is designed to sit alongside one (see the Okta comparison). Proving an identity or authorization claim without revealing its secret is the job of the ZK Platform. Deciding what an authenticated subject is permitted to do — and enforcing that decision — is governed by Agent-008 under authority preserved by the Authority Center. This page reinforces those systems; it does not claim to be the authority layer.
