摘要
A system and method for providing confidentiality against eavesdropping and authentication against impersonation attacks for advanced wireless communication systems are disclosed. The method exploits ARQ as a MAC layer mechanism and artificial noise as a physical layer mechanism with maximal ratio combining to achieve secrecy. An artificial noise, not requiring class space in the channel, is designed and added to the data package based on the QoS requirements and channel condition between legitimate parties. Basically, a special AN, which does not require null-space in the channel, is designed based on the QoS requirements and the channel condition between the legitimate parties and injected to the data packet. If the same packet is requested by the legitimate receiver (Bob), an AN cancelling signal is designed and added to the next packet. Then, an AN-free packet is obtained by using MRC process at Bob, while deteriorating the eavesdropper's performance.
