zk-abe-backend

A backend server including Key Generating Server (KGS) for zk-ABE (Zero-Knowledge Attribute-Based Encryption) system.

Overview

This project implements a backend server for a Zero-Knowledge Attribute-Based Encryption system. It includes a Key Generating Server (KGS) that handles the generation of keys required for the encryption and decryption processes.

Features

• Key Generating Server (KGS) for zk-ABE
• REST API endpoints for key management
• Built with Rust for performance and safety
• Asynchronous handling using Tokio and Warp

Dependencies

1. Warp: A super-easy, composable, web server framework for warp speeds.
2. Serde: A framework for serializing and deserializing Rust data structures efficiently and generically.
3. Tokio: An asynchronous runtime for the Rust programming language.
4. Rabe: A library for attribute-based encryption schemes.

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/zk-abe-backend.git
   cd zk-abe-backend
   

2. Install Rust: If you haven't already, install Rust using rustup

   curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
   source $HOME/.cargo/env
   

3. Build:

   cargo build
   

4. Run the server:

   cargo run
   

5. Use the following curl command to submit the policy:

curl -X POST http://localhost:3031/submit_policy \
-H "Content-Type: application/json" \
-d @policy_template.json
