Zero-Trust State Management for
Post-Quantum Signatures

A decentralized, mathematically infallible infrastructure to prevent state exhaustion and index reuse in LMS and XMSS high-assurance environments.

The Fatal Flaw of Raft

Stateful algorithms like LMS are mathematically bulletproof, but operationally fragile. If a state index is reused, the private key is instantly compromised.

Traditional solutions like Raft (etcd, Consul) rely on trusted administrators. A well-meaning sysadmin restoring an outdated backup can accidentally roll back the index, destroying the security of the entire system.

The Blockchain Solution

DQKMI replaces trusted administrators with an immutable, cryptographically verifiable blockchain using an Event-Driven UTXO model.

The network strictly enforces monotonic index advancement. A sysadmin cannot accidentally roll back a blockchain. xHSMs verify consensus before signing, creating a true Zero-Trust architecture.

Why LMS is Here to Stay

The mandated standard for the next 30 years of high-assurance cryptography.

Conservative Cryptography

Unlike lattice-based math which could be broken by future breakthroughs, LMS relies entirely on SHA-256. Breaking LMS means breaking Bitcoin and the global financial system.

NSA & NIST Mandates

The NSA's CNSA 2.0 mandates LMS for National Security Systems by 2025, with exclusive use by 2030. NIST SP 800-208 standardizes it for secure boot and firmware updates.

Hyperscaler Adoption

Major infrastructure providers and hardware security module (HSM) manufacturers are actively deploying LMS for critical infrastructure attestation and firmware signing.
