Introduction

TARS (Transparent Auditable Resilience System) is an open-source solution for secure and verifiable deployment of WireGuard VPN servers. It ensures server integrity and provenance through cryptographic birth certificates and proof-of-life mechanisms. Designed to treat servers as disposable appliances, TARS allows for dynamic scaling while preserving user privacy and anonymity.

---

Features

• Cryptographic Birth Certificates: Verifies the server's initial state upon deployment.
• Proof-of-Life Signals: Regularly confirms server integrity and detects tampering.
• User Privacy Assurance: Excludes dynamic configurations from integrity checks to maintain anonymity.
• Scalability: Supports dynamic addition and removal of servers.
• Open-Source: Built entirely with open-source tools and libraries.
• Blockchain Integration: Publishes proofs to a public blockchain for transparency.

---

How It Works

1. Deployment: Each server generates a cryptographic birth certificate containing its initial state.
2. Monitoring: The server monitors every bit of its system, excluding specified dynamic files.
3. Proof Publishing: At regular intervals, the server publishes a proof-of-life hash to a public blockchain.
4. Verification: Any party can verify the server's integrity using the public proofs.
5. Tamper Detection: Unauthorized changes trigger verification failures and initiate alerts.

Installation

Prerequisites

• Operating System: Linux-based OS
• Dependencies:
  • WireGuard
  • OpenSSL
  • Python 3.8+
  • Git

Steps

1. Clone the Repository

   git clone https://github.com/BlorpBleep/TARS.git
   cd TARS

2. Install Dependencies

   sudo apt-get update
   sudo apt-get install wireguard openssl python3 python3-pip

3. Install Python Packages

   pip3 install -r requirements.txt

4. Configure TARS

   • Edit the config.yaml file to suit your environment.
   • Specify dynamic files to exclude in the birth certificate.

---

Usage

Generating a Birth Certificate

Run the following command to generate a cryptographic birth certificate:

python3 tars.py --generate-birth-certificate

Starting Proof-of-Life Monitoring

To start the regular proof-of-life checks and publish proofs:

python3 tars.py --start-monitoring

Verifying Server Integrity

Use the verification script to check server integrity:

python3 verify.py --server <server_id>

---

Configuration

config.yaml Parameters

• server_id: Unique identifier for the server.
• excluded_files: List of dynamic files to exclude from integrity checks.
• proof_interval: Time interval (in seconds) between proof-of-life publications.
• blockchain_endpoint: API endpoint for publishing proofs to the blockchain.

Example config.yaml

server_id: "server-12345"
excluded_files:
  - "/etc/wireguard/wg0.conf"
  - "/var/log/*"
proof_interval: 3600
blockchain_endpoint: "https://blockchain.example.com/api/publish"
