Physical layer security (PLS) is a promising paradigm for safeguarding 6G wireless networks by exploiting the inherent characteristics of wireless channels. However, the efficiency of conventional PLS is often limited by fixed orientation antennas. This paper investigates a rotatable antenna (RA)-aided secure multiple-...

A wireless FL system operating under RIS-assisted blocked-link propagation scenarios is considered, and a joint convergence-latency optimization problem is cast as a mixed-integer nonlinear programming (MINLP) problem, and solved using a low-complexity hybrid alternating optimization framework.
