Patent-Pending Technology
Quantum-secure, blockchain-verified PKI built on Hyperledger Fabric. Four provisional patents filed. NIST PQC compliant. Designed for CNSA 2.0 mandates taking effect January 1, 2027.
The Problem
Certificates expire. Keys get stolen. PKI is broken.
Traditional Public Key Infrastructure was designed for a world where quantum computers didn’t exist. That world is ending. NIST’s CNSA 2.0 mandate requires all national security systems to migrate to post-quantum cryptography by January 1, 2027.
Current PKI depends on certificate authorities that create single points of failure, require constant online connectivity, and can’t survive denied, degraded, intermittent, or limited (DDIL) environments. HashBrown replaces that entire model.
- Eliminates certificate authorities as a single point of failure
- ML-DSA-87 (FIPS 204) digital signatures via NIST-standard algorithms
- ML-KEM-1024 (FIPS 203) key encapsulation for quantum-safe key exchange
- Hyperledger Fabric permissioned blockchain for immutable trust records
- Full offline verification in DDIL environments
- Zero-trust architecture with cryptographic proof at every layer
- FedRAMP and CMMC-ready for GovCloud deployment
Patent Portfolio
Four patents. One architecture.
Replaces certificate authority infrastructure with blockchain-anchored trust. Credential issuance, revocation, and verification happen on-chain with cryptographic proof — no central authority required.
ML-DSA-87 signatures and ML-KEM-1024 key encapsulation baked into the credential lifecycle. Quantum-resistant from day one — not bolted on after the fact.
Offline credential verification using cryptographic proofs cached at the edge. Operators in denied or degraded environments authenticate without reaching back to any server.
Cryptographic audit chain with Merkle-anchored ledger proofs. Every identity event is hash-linked and immutable — providing verifiable chain-of-custody for credentials across their entire lifecycle.
Core Capabilities
DSAT — Distributed Security Assertion Token
ML-DSA-87 / RSA dual-signed identity tokens verifiable offline without CA infrastructure. Designed for peer authentication in zero-connectivity environments where a certificate authority cannot be reached.
OAJ — Offline-Accountable Journal
Tamper-evident hash-chained journaling with AES-256-GCM encryption and Merkle-anchored integrity proofs. Every entry is forensically attributable and auditable after reconnection.
AnchoredTime — DDIL Temporal Trust
Multi-source consensus timekeeping with quorum validation and tamper-resistant monotonic clock enforcement. Prevents time-rollback attacks on expiry and replay protection.
ZPE — Zero-Point Enforcement
Policy enforcement engine operating without connectivity. Evaluates trust, authorization, and cryptographic posture locally — then reconciles with the distributed ledger on reconnection.
