# VAZ256™

Verified Abbreviated Zeta 256 bits (VAZ256) - is a post-quantum cryptographic digital signature scheme that combines Dilithium5 and SHAKE256 for secure digital signatures and efficient compressed 32-byte public keys.

## Acknowledgments and Third-Party Code

This project includes modified code from the following open-source projects:

- Parts of CRYSTALS-Dilithium Rust implementation by Quantum Blockchains
  - Original Repository: https://github.com/Quantum-Blockchains/dilithium
  - Original License: GPL-3.0
  - Which itself was ported from the reference implementation at: https://github.com/pq-crystals/dilithium

VAZ256™ is built upon these foundations but includes significant modifications and original work. The name "VAZ256" is a trademark of Fran Luis Vazquez Alonso.

## Features
- Hybrid post-quantum security based on Dilithium5
- Compact 32-byte public keys using SHAKE256
- Pure Rust implementation
- Zero-dependency core functionality
- Comprehensive test suite and benchmarks

## Security Considerations - **Use at Your Own Risk**
- This implementation is currently in development and has not been audited
- Use in production systems is not recommended until formal security analysis is complete

## Performance
Benchmark results and performance characteristics using RockChip RK3562 2.0 GHz.
- Key generation time ~ 1.33 ms
- Signing time ~ 5.00 ms
- Signature verification time ~ 1.01 ms
