Framework Overview

Sovereign control over your hardware & software supply chain

A multi-layered attestation and verification protocol that ensures every component — from silicon to open-source library — meets strict integrity and provenance standards.

Core Principles

The framework is built on three pillars: Root of Trust (hardware-anchored cryptographic identity), Continuous Attestation (runtime verification of firmware and software integrity), and Provenance Tracking (cryptographic chain-of-custody for every component). These pillars work in concert to detect and block tampered or malicious components at every stage of the supply chain — from fabrication to deployment.

Pillar 1

Hardware Root of Trust

Immutable cryptographic identity anchored in silicon. Enables secure boot, measured boot, and attestation of firmware integrity at power-on.

Pillar 2

Continuous Attestation

Runtime verification of all executing code — kernel, drivers, and applications — against signed reference manifests. Detects runtime modifications and side-loaded code.

Pillar 3

Provenance & SBOM

Cryptographically signed Software Bill of Materials (SBOM) and hardware bill of materials (HBOM) with full dependency tracking. Every component is traceable to its source.

Attestation Lifecycle

From silicon to deployment — verifying integrity at every stage

Each stage in the lifecycle includes cryptographic measurement and verification against a known-good baseline.

Stage 1

Manufacturing & Fabrication

Hardware root of trust provisioning, secure key injection, and immutable firmware signing. Each chip is assigned a unique device identity (UDI) signed by the manufacturer's CA.

Protocol: TCG DICE / EAT
Stage 2

Assembly & Integration

Component provenance verification against HBOM. All subcomponents (chips, memory, storage) are cryptographically bound to the final assembly, creating a chain of custody.

Verification: X.509 v3 + SHA-384
Stage 3

Software Composition & SBOM

Automated generation of software bill of materials (SBOM) with dependency resolution. Each library and binary is hashed and signed; vulnerability scanning against NVD and private databases.

Format: SPDX 2.3 + CycloneDX
Stage 4

Secure Boot & Measured Boot

UEFI Secure Boot and TPM-based measured boot capture platform configuration registers (PCRs) for all boot-time components. Remote attestation via TPM 2.0 quote.

Protocol: TPM 2.0 / IMA
Stage 5

Runtime Attestation

Continuous monitoring of running processes, kernel modules, and application memory. Any deviation from the signed baseline triggers an alert and forensic snapshot.

Frequency: 1-second heartbeat
Stage 6

Update & Patch Management

Cryptographically signed updates with re-attestation after each patch. All updates are validated against the SBOM and HBOM before installation, preventing injection of malicious code.

Mechanism: Delta-based + full manifest
Threat Model

Common supply chain attack vectors addressed

The framework is designed to detect and mitigate the most prevalent supply chain threats observed in real-world attacks against critical infrastructure.

VECTOR 1

Malicious Firmware Injection

Adversary implants malicious code into UEFI/BIOS or device firmware during manufacturing or via poisoned updates. This framework detects via measured boot and runtime comparison.

MITRE ATT&CK: T1542 (Pre-OS Boot)
VECTOR 2

Hardware Backdoors

Silicon-level implants (e.g., kill switches, covert channels) inserted during chip fabrication. Detected via hardware root of trust and cryptographic attestation of all microcode.

MITRE ATT&CK: T1098 (Account Manipulation)
VECTOR 3

Open-Source Component Poisoning

Typosquatting, dependency confusion, and malicious code injection in open-source libraries. SBOM generation and continuous vulnerability scanning against known backdoor signatures.

MITRE ATT&CK: T1195 (Supply Chain Compromise)
VECTOR 4

Code Signing Abuse

Stolen or misused code-signing certificates to sign malware. Framework verifies certificate chain and revokes untrusted signers via OCSP/CRL checks at load time.

MITRE ATT&CK: T1553 (Subvert Trust Controls)
Technical Controls

Implementation matrix

Each control maps to a specific threat vector and compliance requirement. All controls are validated against NIST SP 800-193 and FIPS 140-3.
