<h2>Attestation Certificate Authority (ACA) and TPM Provisioning with Trusted Computing-based Supply Chain Validation </h2>

The Host Integrity at Runtime and Start-up Attestation Certificate Authority is a Proof of Concept - Prototype intended to spur interest and adoption of the [Trusted Platform Module (TPM)](https://trustedcomputinggroup.org/work-groups/trusted-platform-module/). It's intended for testing and development purposes only and is not intended for production. The ACA's functionality supports the provisioning of [TPM 2.0](https://trustedcomputinggroup.org/wp-content/uploads/2019_TCG_TPM2_BriefOverview_DR02web.pdf) with an [Attestation Identity Certificate (AIC)](https://www.trustedcomputinggroup.org/wp-content/uploads/IWG-Credential_Profiles_V1_R1_14.pdf). The ACA can be configured to enforce the Validation of Endorsement and Platform Credentials to illustrate a supply chain validation capability.

</p>

The HIRS ACA can be used to perform the Acceptance Test. The HIRS ACA is a web based server which processes Attestation Identity Requests.
The ACA provides a “provisioner” application to be installed on all devices which will be requesting Attestation Certificates.

## Features

### Attestation Certificate Authority (ACA)
<p align="center">
<img src="images/ACA_ValidationReport_PC_Policy.jpg" />
</p>

* Issues Attestation Identity Certificates or TPM based [Local Device ID (LDevID) certificates](https://github.com/nsacyber/HIRS/wiki/DevID-Certificates) to validated devices holding a TPM
* Configures policies for enabling/disabling validation procedures
* Performs TCG-based Supply Chain Validation of connecting clients

* Verifies the provenance of the system's hardware components, such as the motherboard and chassis, by comparing measured component information against the manufacturers, models, and serial numbers listed in the Platform Certificate
* Firmware Integrity Validation
* Uploads and processes [TCG PC Client Reference Integrity Manifests](https://trustedcomputinggroup.org/resource/tcg-pc-client-reference-integrity-manifest-specification/) (RIM)s
* Creates and verifies a nonce for the TPM Quote
* Process TMP Event Logs and checks digests against the TPM Quote
* Verifies individual event digests against the OEM provided Reference Integrity Measurements

### TPM Provisioner
### [TPM Provisioner](https://github.com/nsacyber/HIRS/tree/main/HIRS_Provisioner.NET)
* Requests an Attestation Identity Certificate for the TPM from the ACA.
* Transfer's TCG Artifacts to the ACA (TPM Endorsement Certificates, Platform Certificates, Reference Integrity Manifests, Event Logs, etc.)
* Reads the device's hardware, network, firmware, and OS info for platform and component validation
* Provides a TPM Quote for Firmware Integrity Checking

### [TCG RIM Tool](https://github.com/nsacyber/HIRS/tree/main/tools/tcg_rim_tool)
* Creates , Formats, and Digitally Signs [TCG PC Client Base RIMs](https://trustedcomputinggroup.org/resource/tcg-pc-client-reference-integrity-manifest-specification/)
* Validates the signature of TCG PC CLient Base RIMs

### [TCG Event Log Tool](https://github.com/nsacyber/HIRS/tree/main/tools/tcg_eventlog_tool)
* Parses binary TPM Event Logs and displays event data in a human readable form
* Extracts Events from TPM Event Logs for test pattern generation
* Provides Expected PCR values from a complete TPM Event Log

### [Platform Certificate Creator - PACCOR](https://github.com/nsacyber/paccor/)
* Creates platform certificates according to the [TCG Platform Certificate Profile](https://trustedcomputinggroup.org/resource/tcg-platform-certificate-profile/).
* Assists in gathering all of the data that can go into a PC and produce a signed attribute certificate
* Validates signatures on TCG Platform Certificates
