Efficient hardware realization of 2D-chaotic Baker map using FPGA for secure image encryption

As the digital ecosystem evolves, the widespread generation, transmission, and storage of medical images expose sensitive healthcare data to significant security threats, necessitating robust and efficient encryption techniques. While several chaos-based encryption methods have b...

Adaptive modulation in 6G terahertz systems via online reinforcement learning–PSO meta-optimization

The rapid evolution of sixth-generation (6G) wireless systems has intensified the need for adaptive modulation strategies capable of operating reliably and efficiently in highly dynamic terahertz (THz) communication environments. Conventional threshold-based and static optimizati...
