Research and Simulation Verification of Air-to-ground Wireless Access Authentication Technology
As the interaction between aircraft and ground systems gradually increases,the security risks of wireless communication also gradually become prominent.The airborne scenario involves many organiza-tions such as airborne equipment,airlines,service providers,etc.The basic password authentication meth-od can no longer guarantee the communication security,so a digital certificate-based air-to-ground wire-less access authentication technology for airborne requirements is proposed.Based on the air-to-ground wireless access authentication architecture,this paper summarizes the key technologies involved,including the application of airborne wireless access,public key infrastructure and airport network wireless access authentication service in airborne scenarios,and builds an air-to-ground wireless access simulation envi-ronment based on digital certificate EAP-TLS bidirectional authentication mechanism.The experiment verifies that FreeRadius combined with digital certificate can carry out effective identity authentication and improve the security of air-to-ground communication.
