Explore the QILAHK Trust Framework

The QILAHK Trust Framework formalizes security as cryptographic evidence. This documentation exposes the research, models, boot mechanics, and attestation semantics that transform execution into provable trust.

Research Lineage & Intellectual Foundations

QILAHK does not borrow trust models—it refines and unifies decades of security engineering research into an operational authority framework.

Trusted Computing Group (TCG) measured boot and attestation primitives
NIST SP 800-155, 800-193, 800-207 trust and integrity guidance
Formal chain-of-trust and transitive integrity models
Hardware-backed identity and key provenance research
Failure-domain isolation, revocation, and trust decay theory

Trust Propagation Model

Trust propagates strictly forward. Each stage inherits trust only by verifying the cryptographic measurements of the previous stage. Any break collapses downstream assurance.

Secure Boot Process — Detailed Walkthrough

Stage 1 — Hardware Root of Trust

Execution begins in immutable silicon. Endorsement keys, secure registers, and measurement engines are anchored to hardware that cannot be altered without physical compromise.

Stage 2 — UEFI Firmware Measurement

Firmware volumes, configuration variables, and option ROMs are measured and extended into Platform Configuration Registers (PCRs) prior to execution.

Stage 3 — Bootloader Verification

The bootloader binary, parameters, and signing keys are verified. Any deviation from policy halts execution or invalidates trust inheritance.

Stage 4 — Kernel & Early Module Integrity

Kernel images, initrd contents, command-line parameters, and early drivers are measured before control transfer.

Stage 5 — OS Trust Transition

The operating system inherits trust conditionally, based on alignment with known-good baselines and policy constraints.

Attestation Values & Evidence Semantics

Attestation transforms transient boot measurements into durable, inspectable evidence bound to a hardware identity.

PCR Hash Chains

Ordered hash extensions representing each boot measurement.

Firmware Measurements

UEFI binaries, configuration state, and option ROM integrity.

Bootloader Fingerprints

Exact cryptographic identity of the bootloader and parameters.

Kernel & Module Hashes

Runtime foundation integrity prior to OS handoff.

Attestation Identity Keys

Hardware-backed keys proving genuine platform origin.

Timestamped Nonces

Freshness guarantees preventing replay and forgery.

Verification, Baselines & Trust Mark Issuance

QILAHK evaluates evidence against known-good baselines, revocation intelligence, and policy constraints. Only systems meeting strict integrity criteria receive verification status and Trust Mark eligibility.

The result is not a security claim—but a cryptographically defensible proof of system integrity at a defined moment in time.

Known‑Good Baseline Registry

QILAHK maintains authoritative baseline definitions representing verified, acceptable platform states. Baselines are versioned, timestamped, and cryptographically signed to prevent ambiguity or silent drift.

Platform model and firmware lineage
Approved firmware, bootloader, and kernel hashes
Configuration constraints and revocation conditions
Lifecycle status: active, deprecated, revoked

Attestation evidence is evaluated strictly against the baseline applicable at the time of measurement, ensuring historical defensibility.

Trust Mark Verification Interface

A QILAHK Trust Mark represents a signed assertion that a system met defined integrity criteria at verification time. Each Trust Mark encodes:

Verification timestamp and validity window
Baseline identifier and policy profile
Evidence hash commitment
QILAHK Authority signature

Trust Marks are independently verifiable without reliance on proprietary tooling, preserving transparency and long‑term auditability.

Regulatory & Assurance Alignment

The QILAHK Trust Framework is designed to complement—not replace—regulatory regimes. Verification evidence may be mapped to external controls without diluting authority.

NIST SP 800‑53 and 800‑61 integrity objectives
ISO/IEC 27001 control evidence support
Supply‑chain assurance and platform provenance requirements
Zero‑Trust architecture integrity foundations

Whitepaper Summary

The QILAHK Trust Framework Whitepaper formally defines security verification as a measurable engineering discipline. It introduces trust decay, revocation dynamics, and authority separation as first‑class security concepts.

The whitepaper serves as a canonical reference for enterprises, regulators, and platform vendors seeking provable system integrity.

Public Trust Mark Verifier

The QILAHK Public Verifier enables any party—customers, auditors, regulators, or partners—to independently validate a Trust Mark without privileged access. Verification requires only the Trust Mark payload and the QILAHK public authority key.

Decode Trust Mark metadata (timestamp, baseline, validity)
Verify QILAHK Authority signature
Confirm evidence hash commitment integrity
Check revocation and expiry status

This ensures Trust Marks remain verifiable years after issuance, independent of platform vendor or customer control.

Baseline Registry Index (Read-Only)

QILAHK publishes a read-only index of active and historical baselines. Each entry is immutable once issued and cryptographically signed.

Baseline ID and version lineage
Applicable platform classes
Activation, deprecation, and revocation dates
Associated policy profiles

This index provides external assurance that verification decisions are consistent, repeatable, and free from retroactive manipulation.

Standards & Regulatory Annex

The Standards Annex maps QILAHK verification artifacts to external frameworks without redefining QILAHK authority. This allows organizations to reuse evidence while preserving cryptographic rigor.

NIST SP 800-53 / 61 / 155 evidence mappings
ISO/IEC 27001 and 27002 integrity support
Supply-chain and platform provenance controls
Zero Trust architecture integrity anchors

The annex is designed to support audits, certifications, and regulatory filings without weakening the underlying trust model.
