Joint Secrecy and Covert Communication (JSACC): An Enhanced Physical Layer Security Approach
JSACC dynamically switches between secrecy and covert modes using RIS, derives closed-form outage probability and ergodic rate, shows diversity order depends on Nakagami parameters and RIS elements, and outperforms conventional secrecy communication in simulations.
