An Identity Authentication Scheme Based on SM2 Algorithm in UAV Communication Network

Algorithm 2

Core algorithm of the control station end.

IDu,Ru = clientSocket. recv(1024)#The control station receives the IDu and Ru

res = check(IDu) #The control station checks the IDu

res, content = sm2_station.negotiation(Ru, PU, IDU, option, Rs, Rs)#Key negotiation

if not res:

     print(’error:’, content)

     return

if option:#Generates the negotiation key, the KS

     KS, SS = content

else:

     KS = content

clientSocket. send(message(IDs,Rs)#Send the IDs and Rs to the drone

encData = SM4. encryptSM4(KS, command)#The control station encrypts the instructions using a KS key

clientSocket. send(encData)#Send the text to the drone
