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...

Embodiment 3

[0086] Such as Figure 4 As shown, in the vehicle-road coupling system, the RFID security authentication method for the Internet of Vehicles based on the key distribution center, specifically.

[0087] A. Initialization

[0088] 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 , first combine the stored list with the random number r r Perform the operation, and then refresh the key authorization list L. Before the tag can communicate wit...

Abstract

The invention provides a vehicle network RFID security authentication method based on a key distribution center. In the protocol process stage, the r generated by the reader r sent to the label, and the r r Sent to KDC; tag receives r r after generation r t , calculate b=H(ID i ||r r ||r t ), and a,r t , b is sent to the reader; the reader sends a, r t ,b is sent to KDC; KDC receives a,r t ,b, search for a value that matches a, if there is, the authentication label is legal, KDC generates R, and R,b,r r ,r t Send it to the background server; if not, the authentication label is invalid and the communication is terminated; the background server receives R,b,r r ,r t Afterwards, query the ID value, and calculate c=H(ID j ||r r ||R), and send c, d to the reader; after the authentication tag is invalid, the communication is terminated; the reader forwards c, d to the tag, after the reader is authenticated, the tag updates the key synchronously, otherwise the authentication The reader / writer is invalid, and the communication is terminated. The invention can effectively prevent counterfeit attack, retransmission attack, tracking attack and DoS attack.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles and communication, in particular to an RFID security authentication method for Internet of Vehicles based on a key distribution center. Background technique [0002] RFID (Radio Frequency Identification) radio frequency identification technology is a communication technology that can identify specific targets and read and write related data through radio signals. It is also one of the core technologies of the Internet of Vehicles. The license plate of a car is the ID that stores the vehicle information. The traditional license plate is mainly recognized by visual and image processing technology. The environmental impact is large, the recognition speed is slow, the operating cost is high, and complex software algorithms are required. Therefore, this type of method has been difficult to adapt to the current development trend of intelligent transportation and Internet of Vehicles, and t...
