April 3, 2026 — Sans Peur Strategies, Inc. has filed four provisional patent applications with the United States Patent and Trademark Office covering innovations in quantum-secure identity verification, blockchain-verified public key infrastructure, and offline credential validation for denied, degraded, intermittent, and limited (DDIL) environments.
The patent portfolio protects core inventions within HashBrown, a quantum-secure PKI platform built on Hyperledger Fabric that replaces traditional certificate authority infrastructure with blockchain-anchored trust and NIST post-quantum cryptographic standards.
What the Patents Cover
The four filings address distinct technical challenges in next-generation identity and access management:
- Blockchain-Verified PKI — A method for anchoring credential issuance, revocation, and verification to a permissioned blockchain, eliminating the single point of failure inherent in certificate authority architectures.
- Post-Quantum Credential Engine — Integration of ML-DSA-87 (FIPS 204) digital signatures and ML-KEM-1024 (FIPS 203) key encapsulation into the full credential lifecycle, providing quantum resistance from issuance through verification.
- DDIL-Resilient Verification — A system for offline credential verification using cryptographic proofs cached at the edge, enabling secure authentication in disconnected environments without reaching back to any server.
- Adaptive Trust Provisioning — A mechanism for dynamically adjusting trust parameters based on operational context and connectivity state, maintaining security guarantees across the full spectrum of network conditions.
Why It Matters Now
NIST’s CNSA 2.0 mandate requires all national security systems to transition to post-quantum cryptography by January 1, 2027. Current PKI architectures were not designed for this transition — they depend on certificate authorities that create centralized vulnerabilities and require constant network connectivity that forward-deployed and special operations units often lack.
HashBrown was built from the ground up to solve both problems simultaneously: quantum resistance and offline operation. The technology targets GovCloud deployment under FedRAMP and CMMC compliance frameworks.
