As increasing threat to wireless data communication for mobile edge computing and high cost of conventional encryption implement in wireless environments, the physical layer security has aroused widespread concern to increase the security of data transmission in mobile edge computing. However, too much idealistic and unrealistic assuming in this area’s research result in security can hardly guarantee in the reality. This paper proposed a secure communications for mobile edging computing, which is using the sequcece combining with physical layer beamforming and artificial noise. By contrast to conventional schemes, the proposed scheme could enhance the security with probability 1 in two adverse situation. An advantage of the proposed scheme is that the upper layer can help the physical layer to defend each other, while up-layer system break by opponent, natural randomness of physical channel will play role to ensure system safety. We conduct simulations to verity the effectiveness of the proposed scheme for mobile edging computing.
