Overview

BaelNET is a next-generation Post-Quantum Hybrid Encryption Protocol designed specifically for high-throughput, low-latency transport layers (UDP/QUIC) and large file encryption. It bridges the gap between state-of-the-art cryptographic security and the performance requirements of real-time 8K streaming, High-Frequency Trading (HFT), and massive data storage.

Unlike traditional protocols that bottleneck on sequential processing, BaelNET utilizes a novel Epoch-based Windowed Ratchet, allowing for massive parallelization ($O(N/P)$) while maintaining strict Forward Secrecy.

🛡️ Security Architecture

1. Hybrid Post-Quantum Key Exchange

We employ a "Belt and Suspenders" approach to key negotiation:

• Kyber-768 (NIST ML-KEM): Protects against future Quantum Computer attacks (Store-Now-Decrypt-Later).
• X25519 (Elliptic Curve): Provides established, high-speed classical security.
• Hybrid KDF: Secrets are mixed via BLAKE3 to ensure security holds if either primitive is unbroken.

2. The "Windowed Ratchet" (Scalability)

Standard ratchets (like Signal's) are strictly sequential, limiting throughput to single-core speed. Bael Crypt introduces an Epoch/Frame model:

• Epochs: Sequential rotation for Forward Secrecy (Depth: 1000 frames).
• Frames: Parallelizable key derivation within an epoch. This enables multi-threaded encryption/decryption without locking.

3. Resilience & Auto-Healing

• Sliding Window Replay Protection: A 128-bit bitmask ensures $O(1)$ memory usage, preventing DoS attacks common in HashSet implementations.
• Auto-Healing: The protocol automatically detects dropped "Rotation Packets" and simply fast-forwards the state to sync with the sender, ensuring zero downtime on lossy networks.

4. Advanced Security Features (v3.4)

• Zeroization: All sensitive keys and buffers are securely wiped from memory (zeroized) immediately after use or on drop, protecting against memory dump attacks.
• Constant-Time Operations: MAC verification and key comparisons use constant-time algorithms to prevent timing side-channel attacks.
• Key Confirmation: VPN handshake now includes an encrypted challenge-response phase to verify that both parties possess the correct session keys before exchanging data.

⚡ Performance Benchmarks

Benchmarks were conducted on a 12-Core CPU using the Optimized Parallel Implementation (Rayon).

Validates capability for uncompressed 8K video streams and 10Gbps+ links.

📦 Installation & Usage

From Crates.io (Recommended)

cargo add baelNET

Or manually in Cargo.toml:

[dependencies]

baelNET = "3.4.0"

From Source

[dependencies]

bael_crypt = { path = "." }

Quick Start (Library)

use baelNET::{BaelHandshake, BaelSession};

fn main() -> anyhow::Result<()> {
    // 1. Handshake (Quantum Safe)
    let (s_kyber_pk, s_kyber_sk, s_x_sk, s_x_pk) = BaelHandshake::server_keygen();
    let (msg, client_seed) = BaelHandshake::client_encapsulate(&s_kyber_pk, s_x_pk);
    let server_seed = BaelHandshake::server_decapsulate(&msg, &s_kyber_sk, &s_x_sk);

    // 2. High-Speed Session
    let mut sender = BaelSession::new(client_seed);
    // Encrypt with BAEL_FLAG_DATA (0x00)
    let packet = sender.encrypt(b"Critical Data", 0)?;

    Ok(())
}

🛠️ CLI Tools

File Encryption (bael.sh)

Supports configurable chunk size for optimizing between RAM usage and performance.

# Encrypt with default 64KB chunks

./bael.sh encrypt video.mp4


# Encrypt with custom chunk size (e.g., 1MB for large files on high-RAM systems)

./bael.sh encrypt database.sql --chunk-size 1048576

VPN Server/Client (bael_vpn)

# Start Server

cargo run --release --bin bael_vpn -- server --bind 0.0.0.0:9000


# Start Client

cargo run --release --bin bael_vpn -- client --server 127.0.0.1:9000 --message "Hello Quantum World"
