A secure multilayer audio encryption scheme based on chain ring algebraic S-boxes, Rössler diffusion, and 4D hyperchaotic permutation

The secure transmission of digital audio requires encryption techniques that can protect audio information against different types of cryptanalytic attacks. Existing chaos-based audio encryption methods commonly use conventional $$\:GF\left({2}^{8}\right)$$ -based substitution boxes (S-boxes) and a single low...

Zero-Shot Cross-Domain Anomaly Detection for Water ICS: A PLC-Based Dataset and Transfer Learning Evaluation Across Heterogeneous Benchmarks

This study proposes a zero-shot cross-domain intrusion detection framework for industrial control systems (ICS) using a canonical feature representation and domain-adversarial learning. While prior approaches relied on labeled target data, the proposed method generalizes across heterogeneous SCADA datasets without targ...
