Deon Protocol v1.3.1

Repository: https://github.com/brzb0/Deon-Protocol

A secure, high-performance file transfer protocol implementation in Rust, featuring SPAKE2 authentication, ChaCha20-Poly1305 encryption, and intelligent Wi-Fi handover.

Features

• Secure Authentication: Uses SPAKE2 (Password-Authenticated Key Exchange) to prevent MITM attacks.
• Strong Encryption: All data is encrypted using ChaCha20-Poly1305 with epoch-based nonces.
• Smart Handover: Automatically switches from BLE (simulated) to Wi-Fi for files larger than 64KB.
• Resilience: Implements token bucket rate limiting and exponential backoff for network reliability.
• Efficiency: 64KB chunking for optimal throughput.

Installation

Ensure you have Rust installed.

git clone https://github.com/brzb0/Deon-Protocol
cd deon-protocol/deon_protcol
cargo build --release

Usage

./target/release/deon_protocol receive --port 8080 --password "123456"

Send a File

Send a file to the receiver.

./target/release/deon_protocol send --file "document.pdf" --address "127.0.0.1:8080" --password "123456"
