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