Resource Allocation for Enhancing Offloading Security in NOMA-Enabled MEC Networks

This paper studies an uplink nonorthogonal multiple access (NOMA)-enabled mobile-edge computing network. Specifically, we focus on the practical design of secure offloading without knowing eavesdropper's channel state information. The aim is to maximize minimum antieavesdropping ability (AEA) for NOMA users subject worst-case secrecy rate requirements and limited transmission power budgets. formulated problem nonconvex difficult be solved directly. In order tackle this issue, propose efficient iterative algorithm by jointly designing rate, local bits, allocation. bits allocation are derived in closed form. Numerical results provided demonstrate efficiency our proposed scheme terms AEA.
