Embodiment 1
[0046] Such as figure 2 As shown, in the parking lot toll station scenario, the RFID security authentication method for the Internet of Vehicles based on the key distribution center, specifically.
[0047] A. Initialization
[0048] Each tag stores its ID i As its unique identity, the ID i Assigned by the background server, that is, only the tag and the back server share the ID i . id r It is the ID of the reader, and is shared by the reader and the background server. k i,j Represents identity as ID i The private key of the j-th session of the label is allocated and shared by the KDC. After each session is completed, the KDC and the label update the private key synchronously. KDC is the key distribution center, which stores a key authorization list L, when KDC receives the random number r sent by the reader r When , first combine the stored key authorization list L with the random number r r Perform the operation, and then refresh the key authorization list L. Befo...
Embodiment 2
[0067] Such as image 3 As shown, in the mobile identification, the vehicle network RFID security authentication method based on the key distribution center, specifically.
[0068] A. Initialization
[0069] Each tag stores its ID i As its unique identity, the ID i Assigned by the background server, that is, only the tag and the back server share the ID i . id r It is the ID of the reader, and is shared by the reader and the background server. k i,j Represents identity as ID i The private key of the j-th session of the label is allocated and shared by the KDC. After each session is completed, the KDC and the label update the private key synchronously. KDC is the key distribution center, which stores a key authorization list L, when KDC receives the random number r sent by the reader r When , first combine the stored key authorization list L with the random number r r Perform the operation, and then refresh the key authorization list L. Before the tag can communicate...
