Step S302: the wireless car key control system sends first session data to the wireless car key, receives second session data fed back by the wireless car key, generates a session key, encrypts the second session data by using the session key to generate a first authentication ciphertext, and sends the first authentication ciphertext to the wireless car key.
The first session data is automobile end session data which is randomly generated when the wireless automobile key control system initiates an authentication request, and the second session data is automobile key end session data which is responded to the wireless automobile key control system after the automobile key receives the automobile end session data. Before encrypting the authentication ciphertext, the wireless vehicle key control system and the vehicle key are required to generate the same session key by using the same authentication master key and session data, wherein the session data is composed of vehicle-end session data and vehicle-key-end session data.

Further, the identifying and checking the first code in the step S401 may include, but is not limited to:
step S4011: the wireless car key determines whether the first code matches a wireless car key control system code stored in the wireless car key.
Step S4012: the wireless car key checks whether the first code is in the second blacklist.
The second blacklist is a blacklist of a wireless car key control system in the wireless car keys.
Step S4013: if the first code matches the wireless car key control system code and the first code is not in the second blacklist, the wireless car key confirms that the pairing of the vehicle with the first code and the wireless car key with the second code is successful.
Step S402: the wireless car key receives the first session data sent by the wireless car key control system, sends the second session data to the wireless car key control system, receives the first authentication ciphertext sent by the wireless car key control system, generates a session key by the wireless car key, and decrypts the first authentication ciphertext by the session key to generate fourth session data.
The vehicle key and the wireless vehicle key control system generate the same session key by using the same authentication master key and session data corresponding to the step S302, where the session data is a composition of vehicle-end session data and vehicle-key-end session data. The fourth session data is decrypted wireless car key end session data, and is used for comparing with the second session data, namely judging whether the original generated car key end session data is consistent with the decrypted car key end session data or not.
Step S403: if the fourth session data is consistent with the second session data, the wireless car key confirms that the identity of the wireless car key control system is legal, the wireless car key reads fingerprint scanning data and matches the fingerprint scanning data, the session key is used for encrypting the fingerprint matching result and the first session data to generate a second authentication ciphertext, and the second authentication ciphertext is sent to the wireless car key control system.

step S4031: and comparing whether the fingerprint scanning data of the wireless car key is matched with the preset fingerprint of the car owner in the wireless car key.
Step S4032: if the fingerprint scanning data is matched with the vehicle owner fingerprint preset in the wireless vehicle key, the wireless vehicle key confirms that the identity of the user of the wireless vehicle key is legal.
Based on the NFC card car key in fig. 1 and the NFC car key control system in fig. 2, it is first required that a car owner presses a finger, which has already recorded fingerprint data, on a fingerprint sensor of a car key, and attaches the car key to an NFC card reader of a car body, when the NFC card reader of the car detects the NFC card car key, a near field communication connection is established, and an authentication process for the car key is started, where the car key authentication process includes three main stages: the first stage is vehicle pairing, the second stage is mutual identity authentication of the vehicle owner and the vehicle, and the third stage is vehicle judging the control authority of the vehicle key.
The NFC car key control system at the car end in the car pairing process recognizes and checks the code by sending a unique code of the car, namely a first code, to the NFC card car key, and simultaneously requires the NFC card car key to respond to the unique code of the car key, namely a second code, to the NFC car key control system, and recognizes and checks the code by the NFC car key control system, wherein the unique code of the NFC card car key is a unique code distributed by an automobile OEM factory for each NFC card car key, and the unique code of the car is a unique code distributed by the automobile OEM factory for each car. The automobile NFC car key control system and the NFC card car key have stored unique numbers of both sides, and the identification of the second code is to compare whether the code is the same as the stored unique number of the NFC card car key; in addition, the NFC car key control system and the NFC card car key are provided with respective blacklists, wherein the first blacklist is the blacklist of the NFC car key control system aiming at the car key, and the second code is checked to judge that the second code is not in the blacklist of the car key of the NFC car key control system; if the above condition is satisfied, it is indicated that the vehicle and the vehicle key are successfully paired.
After pairing is completed, the automobile NFC car key control system actively initiates a bidirectional identity authentication process request, the bidirectional identity authentication is based on a symmetric encryption and decryption algorithm, the NFC card car key and the automobile NFC car key control system must use the same identity authentication master key, then the two parties obtain a session key based on session data which are different in each bidirectional identity authentication, and the session key is used for calculating to generate an identity authentication ciphertext, and the steps correspond to the steps of: the wireless car key control system generates a session key, and encrypts second session data by using the session key to generate a first authentication ciphertext; and the wireless car key generates a session key, and encrypts the fingerprint matching result and the first session data by using the session key to generate a second authentication ciphertext.
The bidirectional identity authentication process comprises the following steps: after receiving the request of the two-way identity authentication process, the NFC card car key starts a fingerprint sensor on the card to execute fingerprint scanning of the car owner, and if no fingerprint is detected, the NFC card car key control system responds to failure of the two-way identity authentication and refuses to execute car control operation requested by the car key; if the fingerprint is detected on the fingerprint sensor, preprocessing the fingerprint data, transmitting the fingerprint data to a security module of the NFC card car key for fingerprint matching verification, and temporarily storing a matching result, wherein the matching result is successful or failed; and after the NFC card car key finishes fingerprint matching, encrypting the fingerprint matching result by using the session key to generate a car key identity authentication ciphertext, namely a second authentication ciphertext in the steps, and responding to the car NFC car key control system.
The automobile NFC automobile key authentication system checks an automobile key identity authentication ciphertext, and the method comprises the following steps of: firstly, the automobile NFC automobile key control system decrypts an automobile key identity authentication ciphertext by using the same session key and decryption algorithm; then, checking whether the decrypted vehicle key data format is correct or not, wherein the data format is customized by an automobile OEM factory; if the automobile NFC automobile key control system checks that the matching of the fingerprints of the automobile owners is unsuccessful, refusing to execute the automobile control operation requested by the automobile key; when the conditions are met, the automobile NFC automobile key control system allows automobile control operation requested by an automobile key, and sends corresponding automobile control instructions to an automobile control module to finish the automobile control operation.
Referring to fig. 5, an automobile control algorithm diagram based on a wireless automobile key is provided in an embodiment of the present invention. The algorithm is further described with reference to fig. 1 and 2:
step S501: the vehicle owner needs to slightly press the matched finger on the fingerprint sensor before pressing the vehicle key to the position of the automobile NFC reader, and then press the matched finger to the NFC reader, and when the automobile NFC reader detects the NFC card vehicle key 100, a near field communication connection based on the standard IEEE14443 contactless communication protocol is established, and it is noted that the NFC reader may be the automobile door NFC reader module 202 or the central control NFC reader module 203.
Step S502: after the NFC card car key 100 establishes a communication connection with the NFC card reader, the car key authentication process is started from the car NFC car key control system 200 end: the NFC car key control system 200 sends a car key application selection instruction to the NFC card car key 100 through the NFC reader, wherein the selection instruction contains a car key Application Identification (AID) that is uniformly customized by the OEM car factory or industry alliance in which the OEM car factory participates. If the NFC card car key 100 cannot identify the car key application AID, step S504 is performed, otherwise step S503 is continued.
Step S503: after the NFC car key control system 200 successfully selects the NFC car key application, the pairing process of the car and the car key is continuously performed: the NFC car key control system 200 sends a car key authentication initialization command, where the data field of the initialization command at least includes a car unique number and session data, and the purpose of the car end session data is to protect the authentication master key of both parties, and a random number may be used. After receiving the car unique number and the session data, the NFC card car key 100 checks whether the car unique number exists, and the 'presence check' is that the externally input car unique number is compared with the car unique number preset in the NFC card car key 100 by the OEM car factory; if the NFC card car key 100 checks that the currently input car unique number does not exist, step S504 is performed. If the NFC card car key 100 checks that the currently input car unique number exists, in response to the car key unique number and the car key end session data, the NFC car key control system 200 receives and checks whether the car key unique number is legal, where the legal is both existing and not in the car key blacklist, and if the car key is illegal, step S504 is executed; otherwise, step S505 is continued.
Step S504: the vehicle pairing fails, the automobile NFC car key control system no longer performs the subsequent car key authentication process, disconnects the near field communication with the NFC card car key 100 and denies the car control operation of the car key application.
Step S505: after the pairing of the vehicle and the vehicle key is completed, the NFC vehicle key control system 200 and the NFC card vehicle key 100 generate the same session key by using the same authentication master key, session data and a session key calculation method, wherein the session data is formed by vehicle-end session data and vehicle-key-end session data; and continuously executing the identity validity authentication of the car key and the car.
Step S506: the NFC car key control system 200 encrypts car key side session data using the session key generated in step S505 to generate a car side identity authentication ciphertext and transmits the car side identity authentication ciphertext to the NFC card car key 100.
