Description

Technical Field

[0001] This invention relates to the field of quantum communication and information security, and in particular to a quantum-secure intelligent car automatic parking and retrieval system and method. Background Technology

[0002] With the rapid development of intelligent vehicles and autonomous driving technologies, automatic parking systems for intelligent vehicles are gradually emerging, providing convenient parking services for users. Automatic parking systems involve the security of critical information such as vehicle location, vehicle privacy data, and vehicle control commands. Current systems primarily use asymmetric cryptographic algorithms to protect the secure transmission of data over the network. However, with the improvement of computing power, asymmetric cryptography faces the risk of being cracked, easily leading to data leakage within the system, especially vehicle control commands. Once stolen or misused by attackers, it will pose a serious threat to vehicle security. Simultaneously, information leakage can also easily lead to the leakage of car user privacy information, causing significant adverse effects on users. Furthermore, asymmetric cryptographic algorithms, based on computational complexity, suffer from low encryption efficiency. Therefore, to protect user data security and improve encryption efficiency, a more secure and efficient security system is needed. Summary of the Invention

[0028] Figure 3 An example of the automatic vehicle retrieval steps of the quantum-safe intelligent car automatic parking and retrieval method according to the present invention is shown. Detailed Implementation

[0029] In the following description, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided by way of example in order to fully convey the spirit of the invention to those skilled in the art. Therefore, the invention is not limited to the embodiments disclosed herein.

[0030] Figure 1 An example of a quantum-safe intelligent car automatic parking and retrieval system according to the present invention is shown.

[0031] Intelligent vehicle automated parking and retrieval systems may include a parking management system, a user terminal, an intelligent vehicle, and roadside equipment (RUS).

[0032] As the control center of the entire intelligent vehicle automatic parking and retrieval system, the parking management system is mainly used for managing information related to intelligent vehicles and parking lots, planning parking / retrieval routes, parking fee calculation, and quantum security-related functions.

[0033] The user terminal is mainly used to allow users to control vehicle parking and retrieval, as well as to transmit related control commands using quantum key encryption.

[0034] Intelligent vehicles are mainly used for information interaction with roadside equipment, automatically driving to designated locations according to parking / retrieval routes planned by parking management systems, and quantum security-related functions.

[0035] Roadside equipment is mainly used to identify intelligent vehicles and interact with them, send encrypted intelligent vehicle information to the parking management system, perform entry / exit operations (such as raising the barrier to allow passage), and perform quantum security-related functions.

[0036] like Figure 1 As shown in the example, the parking management system may include a quantum random number module, a quantum key generation terminal A, a quantum security module, a route planning module, a billing management module, a network communication module, a quantum key storage module, and a system management module.

[0037] The user terminal may include a user control module, a quantum key storage module, a quantum security module, a satellite positioning module, and a network communication module.

[0038] Roadside equipment may include a quantum key generation terminal B, a quantum security module, a tag reading module, a network communication module, and a RUS control module.

[0039] Intelligent vehicles may include vehicle control modules, quantum security modules, quantum key storage modules, on-board electronic tags, and network communication modules.

[0040] like Figure 1 As shown, the parking management system, user terminal, intelligent vehicle, and roadside equipment can communicate with each other via their respective network communication modules, such as through the Internet. Simultaneously, the tag reading module of the roadside equipment and the on-board electronic tag of the intelligent vehicle can exchange information via RFID communication; the quantum key generation terminal A of the parking management system and the quantum key generation terminal B of the roadside equipment can exchange data via an optical path (such as a fiber optic link or a free-space link).

[0041] In the parking management system of the present invention, a quantum random number module is used to generate quantum random numbers for use as quantum keys.

[0042] exist Figure 1 In the example, the different quantum random numbers generated by the quantum random number module will be used as the quantum key UserKey shared between the parking management system and the user terminal, the quantum key CarKey shared between the parking management system and the intelligent vehicle, and the quantum key CarRand1 between the roadside device and the intelligent vehicle, respectively, for encrypted transmission between each pair. Specifically, the quantum keys UserKey and CarKey can be distributed by the parking management system to the user terminal and the intelligent vehicle, respectively, via near-end injection; the quantum key CarRand1 can be distributed by the parking management system to the intelligent vehicle and the roadside device, respectively, using the encrypted transmission between the parking management system and the intelligent vehicle, and the encrypted transmission between the parking management system and the roadside device.

[0043] Quantum key generation terminal A and quantum key generation terminal B are used to generate quantum keys QKey through a quantum key distribution process, so as to realize the distribution of quantum keys QKey shared between the parking management system and roadside equipment.

[0044] A quantum key storage module is used to store quantum keys locally. For example, a quantum key storage module in a parking management system can store a quantum key UserKey, and simultaneously label it with a user identifier UserID associated with that quantum key UserKey, to establish a one-to-one correspondence between the quantum key UserKey and the user; and store a quantum key CarKey, and simultaneously label it with a smart car identifier CarID associated with that quantum key CarKey, to establish a one-to-one correspondence between the quantum key CarKey and the smart car.

[0045] The quantum security module is used to perform encryption and decryption operations on business data using quantum keys to provide quantum security-related functions, such as encrypted transmission of business data.

[0046] For example, when distributing the quantum key CarRand1 between roadside equipment and a smart car, the parking management system can use its quantum security module to encrypt CarRand1 using the quantum key CarKey to generate a first ciphertext, and then use the quantum key QKey to encrypt CarRand1 again to generate a second ciphertext. CarRand1 is then distributed to both the smart car and the roadside equipment in the first and second ciphertext forms, respectively. When the smart car receives the first ciphertext, it can use its quantum security module to decrypt it using the same quantum key CarKey to obtain the plaintext of CarRand1. Similarly, when the roadside equipment receives the second ciphertext, it can use its quantum security module to decrypt it using the same quantum key QKey to obtain the plaintext of CarRand1, thus achieving encrypted transmission of the quantum key CarRand1.

[0047] The route planning module is used to automatically generate parking route Line1 and retrieval route Line2 based on the location information of intelligent vehicles, roadside equipment and / or user terminals.

[0048] For example, in automatic parking, the route planning module can select a parking location based on the remaining parking spaces in the parking lot and generate a parking route Line1 accordingly; in automatic vehicle retrieval, the route planning module can generate a retrieval route Line2 based on the parking location, the user terminal location, and the roadside equipment used for exiting the parking lot.

[0049] The billing management module is used to enable billing management based on parking duration. For example, during automatic vehicle retrieval, the billing management module can find the entry time T1 based on the smart car identifier CarID, calculate the parking duration T and parking fee based on the current time T2, and deduct the corresponding parking fee from the user's account based on the smart car identifier CarID and the corresponding user identifier UserID.

[0050] The RUS control module is used to control roadside equipment to execute entry / exit commands (which are sent by, for example, the parking management system), such as raising the barrier to allow passage.

[0051] The vehicle control module is used to control the intelligent vehicle to automatically drive to the designated location according to the parking route Line1 or the retrieval route Line2.

[0052] The user control module is used to allow users to generate vehicle retrieval requests. In this invention, the vehicle retrieval request may include information such as the vehicle identifier CarID, the user terminal location UserLoc, and the retrieval instruction.

[0053] The satellite positioning module is used to obtain location information such as the user terminal location (UserLoc).

[0054] To better understand the specific settings and functions of each device and module, the following text will combine... Figure 2-3 The present invention describes a quantum-safe intelligent car automatic parking and retrieval method.

[0055] The intelligent vehicle automatic parking and retrieval method of the present invention may include a key distribution step, an automatic parking step, and an automatic retrieval step.

[0056] The key distribution step is used to distribute the quantum key UserKey between the parking management system and the user terminal, the quantum key CarKey between the parking management system and the intelligent vehicle, and the quantum key QKey between the parking management system and the roadside equipment.

[0057] As mentioned earlier, in this key distribution step, quantum key generation terminal A and quantum key generation terminal B can be used to generate a one-to-one shared quantum key Qkey between the parking management system and the roadside equipment using quantum key distribution technology.

[0058] The parking management system can use a quantum random number module to generate a random number UserKey for the user terminal, and then inject the random number UserKey into the user terminal through a near-end injection method. At the same time, the UserKey is stored in the quantum key storage module and labeled with the user identifier UserID. Meanwhile, the user terminal stores the quantum key UserKey in its quantum storage module, thereby realizing the distribution of the quantum key UserKey between the parking management system and the user terminal.

[0059] Similarly, the parking management system uses a quantum random number module to generate a random number CarKey for the smart car, and injects the random number CarKey into the smart car through a near-end injection method. At the same time, the CarKey is stored in the quantum key storage module and labeled with the smart car identifier CarID. Meanwhile, the smart car stores the quantum key CarKey in its quantum storage module, thereby realizing the distribution of the quantum key CarKey between the parking management system and the smart car.

[0060] In this invention, to ensure the security of the quantum keys, including the quantum keys UserKey and CarKey, the quantum keys can be updated after being used once (e.g., for encryption or authentication), i.e., a "one-time pad" encryption method is adopted. This can be achieved using an encryption algorithm based on the "XOR" operation.

[0061] As an example, to update the quantum key, the parking management system can simultaneously encrypt and transmit the updated quantum key UserKey' to the user terminal when transmitting encrypted business data using the existing quantum key UserKey. For instance, when encrypting business data using the existing quantum key UserKey, the parking management system can use a quantum random number module to generate a new random number UserKey', encrypt the new random number UserKey' using the existing quantum key UserKey, and send the encrypted business data and the new random number UserKey' together to the user terminal. The user terminal can then decrypt the data using the existing quantum key UserKey to obtain the plaintext of the business data and the new random number UserKey', updating the quantum key UserKey to the new quantum key UserKey'. The quantum key CarKey can also be updated in a similar way, so it will not be elaborated here.

[0062] Figure 2 An example of the automatic parking step in the intelligent vehicle automatic parking and retrieval method according to the present invention is shown.

[0063] like Figure 2 As shown, the automatic parking steps of the present invention may include the following operations:

[0064] When a smart car arrives at the parking lot entrance, the roadside equipment at the entrance uses its tag reading module to read the smart car's on-board electronic tag via RFID communication to obtain the smart car's CarID.

[0065] The roadside equipment and the parking management system use their respective quantum key generation terminals to generate a shared quantum key Qkey1 through quantum key distribution technology. After encrypting the smart car identifier CarID with the quantum key Qkey1, the encrypted ciphertext is sent to the parking management system.

[0066] The parking management system uses the same quantum key Qkey1 to decrypt the ciphertext of the smart car identifier CarID to obtain the plaintext of the smart car identifier CarID. At the same time, it also uses a quantum random number module to generate a random number CarRand1. Based on the obtained smart car identifier CarID, it searches for the shared quantum key CarKey, and uses the quantum key CarKey to encrypt the quantum key CarRand1 to generate the ciphertext CarRand1'. The ciphertext CarRand1' is then used to encrypt the quantum key CarRand1 and send it to the smart car.

[0067] In addition, the parking management system also uses a route planning module to generate a parking route Line1 for the smart car based on the availability of parking spaces, and generates a shared quantum key Qkey2 with the roadside equipment. The quantum key Qkey2 is used to encrypt the CarRand1||Line1||RSU command (such as the gate lifting command) to obtain ciphertext (CarRand1||Line1||RSU command)'. The CarRand1||Line1||RSU command is then encrypted and sent to the roadside equipment using this ciphertext.

[0068] In addition, the parking management system can also record the smart car identifier CarID, its entry time T1, and the planned parking location CarLoc.

[0069] After receiving the ciphertext (CarRand1||Line1||RSU command), the roadside equipment can decrypt the ciphertext using the same quantum key Qkey2 to obtain the plaintext of the quantum key CarRand1, the parking route Line1, and the RSU command.

[0070] Therefore, the roadside equipment can perform entry operations according to the RSU command. At the same time, the parking route Line1 can be encrypted using the quantum key CarRand1 to obtain the ciphertext Line1', and then the encrypted parking route Line1 can be sent to the smart car using the ciphertext Line1'.

[0071] After receiving the ciphertext CarRand1', the intelligent car can decrypt it using the same quantum key CarKey to obtain the plaintext of the quantum key CarRand1. Therefore, it can use the quantum key CarRand1 to decrypt the received plaintext Line1' to obtain the plaintext of the parking route Line1, and then automatically drive to the designated parking space (e.g., CarLoc) according to the parking route Line11.

[0072] Figure 3 An example of the automatic vehicle retrieval step in the intelligent vehicle automatic parking and retrieval method according to the present invention is shown.

[0073] like Figure 3 As shown, the automatic vehicle retrieval step of the present invention may include the following operations:

[0074] The user terminal generates a vehicle retrieval request based on the user's control. It then encrypts the retrieval request using the shared quantum key UserKey between the user terminal and the parking management system, generating a ciphertext retrieval request. This ciphertext, along with the user identifier UserID, is sent to the parking management system. The retrieval request may include information such as the intelligent vehicle identifier CarID, the user terminal location UserLoc, and the retrieval command.

[0075] After receiving the encrypted vehicle retrieval request and the user identifier (UserID), the parking management system can retrieve the corresponding quantum key (UserKey) from the quantum key storage module based on the UserID. The UserKey is then used to decrypt the encrypted retrieval request to obtain the plaintext, which includes the vehicle identifier (CarID), the user terminal location (UserLoc), and the retrieval instruction. Preferably, the parking management system can also calculate the parking duration (T = T2 - T1) and parking fee based on the current time (T2). The billing management module then deducts the parking fee from the corresponding user account based on the parking duration (T), the user identifier (UserID), and the vehicle identifier (CarID).

[0076] The parking management system can therefore select the best roadside device (e.g., the roadside device closest to the user terminal) for the smart car to exit based on the user terminal location UserLoc, so that the retrieval route Line2 can be generated based on the smart car location CarLoc, the user terminal location UserLoc, and the location information of the best roadside device; and, based on the smart car identifier CarID, the corresponding quantum key CarKey is retrieved from the quantum key storage module, and the retrieval route Line2 is encrypted to generate ciphertext Line2', so that the retrieval route Line2 can be encrypted and sent to the smart car with the help of ciphertext Line2'.

[0077] Simultaneously, the parking management system uses a quantum key generation terminal and the optimal roadside equipment to generate a shared quantum key Qkey3. This Qkey3 is then used to encrypt the vehicle identification number (CarID) and exit instructions, generating ciphertext. This ciphertext is then sent to the optimal roadside equipment. Correspondingly, the optimal roadside equipment uses the same Qkey3 to decrypt the received ciphertext, obtaining the plaintext of the vehicle identification number (CarID) and exit instructions.

[0078] After receiving the encrypted route Line2', the intelligent vehicle uses the quantum key CarKey shared with the parking management system to decrypt the encrypted route Line2' to obtain the plaintext of the route Line2, and then performs autonomous driving based on the route Line2.

[0079] When the intelligent vehicle automatically drives to the parking lot exit corresponding to the optimal roadside equipment according to the retrieval route Line2, the optimal roadside equipment uses its tag reading module to read the intelligent vehicle's on-board electronic tag to obtain the intelligent vehicle identification CarID. Based on the intelligent vehicle identification CarID, it executes exit instructions, such as raising the barrier to allow passage. Thus, the intelligent vehicle can continue to automatically drive to the designated location, such as the user terminal location UserLoc, according to the retrieval route Line2.

[0080] In summary, this invention proposes a quantum-secure automatic parking and retrieval system and method for intelligent vehicles, utilizing quantum key distribution technology. Specifically, it allows the distribution of shared quantum keys among the parking management system, the intelligent vehicle, the user terminal, and roadside equipment using quantum key distribution technology. This provides secure data transmission between each pair of components and offers higher security compared to traditional key distribution methods based on cryptographic algorithms, unaffected by security threats posed by increased computing power leading to the cracking of cryptographic algorithms. Furthermore, the shared quantum key generated by quantum key distribution technology and the random numbers generated by the quantum random number module are both quantum random numbers, exhibiting higher randomness and thus enhanced security. Simultaneously, the one-time pad encryption method used for data transmission, combined with quantum key distribution technology, achieves theoretically the highest security, significantly improving the security of data interaction during automatic parking and retrieval, and enhancing the privacy and security of intelligent vehicle users' data, as well as the safety of autonomous driving.

They do not limit the scope of the present invention. Those skilled in the art can make various combinations, modifications and equivalent substitutions to the above embodiments without departing from the spirit and scope of the present invention.
