Data Privacy and Security in the Quantum Era: A Comparative Evaluation between Classical and Post-Quantum Cryptography

The emergence of quantum computing threatens the security of widely deployed public-key cryptographic systems such as RSA and elliptic curve cryptography. In response, the National Institute of Standards and Technology (NIST) standardized a new generation of post-quantum algorithms including ML-KEM and ML-DSA. This pap...

A Low-Cost IoT Architecture for Micro-Zone Climate Prediction and Meteorological Forecasting

This article presents the design and deployment of ClimaBogotá v1.2, a climate prediction system tailored for high-altitude urban micro-zones in Bogotá, Colombia. The system combines low-cost IoT sensing, machine learning modeling, and cloud-based orchestration to enable scalable and affordable meteorological forecasti...

Adaptive Quantum-Classical Cryptographic Selection: An RL-Based Architecture for DN25

We present Q-OPSEC, an adaptive middleware that uses supervised, unsupervised and reinforcement learning to select cryptographic strategies from classical, post-quantum and quantum-assisted (QKD) options. The selection is modeled as a multi-objective MDP that balances security, latency, computational and energy cost, a...
