Design and Implementation of a Quantum-Assisted Digital Signature

Cryptography
We propose a new quantum-assisted digital signature (Q-DS) protocol based on the composite of truly random symmetric keys generated by quantum key distribution with secure standardized hash functions, which allows for high parameterization to provide ...

A GPU-Accelerated High-Performance Design for CRYSTALS-Dilithium Digital Signature

2025 IEEE International Conference on Consumer Electronics (ICCE)
Our approach leverages the massive parallelism and computational power of a modern graphics processing unit (GPU) to accelerate CRYSTALS-Dilithium's key operations. While post-quantum cryptographic algorithms like Dilithium offer robust security, they face computational challenges in high-throughput scenarios.
