Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to an unlocking method and a related system. BACKGROUND

[0002] The intelligence of modern automobile products provides users with more intelligent functions and better driving experiences. For example, through a Bluetooth non-sensing intelligent entry system, a user can easily unlock a car without carrying a physical key, which is convenient and fast and provides a good driving experience. The principle of the Bluetooth non-sensing intelligent entry function is to detect the distance between a smart device held by a user and a car by calculating a Bluetooth received signal strength indication (RSSI) value, to determine whether the car meets a safe unlocking condition, so as to realize the keyless unlocking application of the car.

[0003] However, the Bluetooth non-sensing intelligent entry system based only on distance cannot prevent a broadcast relay attack, which has a security risk. The broadcast relay attack is that an attacker respectively deploys relay devices between a smart device held by a user and a car, and forwards Bluetooth communication data at a long distance, so as to simulate a reasonable keyless unlocking condition, which can illegally unlock the car without the user's knowledge, and thus the user may face the risk of property loss.

[0004] Therefore, how to improve the unlocking security of a to-be-unlocked device is a problem to be solved at present. SUMMARY

[0083] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0084] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0085] In this document, the term "embodiment" means that a particular feature, result, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0086] First, in order to facilitate understanding of the embodiments of this application, the specific technical problems to be solved by this application will be further analyzed and proposed.

[0087] Currently, there are various technical solutions for implementing contactless intelligent entry technology. The following are three examples:

[0088] Option 1: Enhanced Seamless Smart Entry Technology Based on RSSI Values

[0089] To prevent broadcast relay attacks during Bluetooth-enabled seamless smart entry, the distance between the smart terminal and the vehicle is calculated by obtaining their GPS location information and compared with the distance calculated using the Bluetooth RSSI value, which improves security to some extent.

[0090] The disadvantage of this solution is that, due to the addition of a GPS positioning module, the system can only be used when both the vehicle and the smart terminal are connected to the network, thus limiting its applicability.

[0091] Option 2: Enhanced Seamless Smart Entry Technology Based on Bluetooth Signals

[0092] In order to prevent the broadcast relay attack in the execution of the Bluetooth non-sensing intelligent entry process, the strength and direction of the Bluetooth signal are verified, and the security is improved to a certain extent.

[0093] The disadvantage of the second scheme is that after the Bluetooth signal is transmitted through the broadcast relay, the signal strength and direction still have the possibility of being consistent with the original signal, which may cause the broadcast relay attack defense to fail, and the security problem exists in the scheme.

[0094] The third scheme: enhanced non-sensing intelligent entry technology method based on gesture verification

[0095] In order to prevent the Bluetooth non-sensing intelligent entry system from encountering the broadcast relay attack, the gesture verification process initiated by the owner is added, and the security of the system is improved to a certain extent.

[0096] The disadvantage of the third scheme is that the convenience of using the intelligent entry system is reduced, and the user experience is poor.

[0097] Therefore, the technical problems to be solved by the present application can include: how to improve the unlocking security of the to-be-unlocked device, and then improve the reliability of the non-sensing intelligent entry system, and reduce the risk of the to-be-unlocked device encountering the broadcast relay attack.

[0098] In order to better understand the technical scheme of the embodiments of the present application, the application scenarios of the unlocking provided by the embodiments of the present application will be introduced below.

[0099] Please refer to Figure 1 , Figure 1 is a schematic diagram of a network architecture provided by the embodiments of the present application. As Figure 1 shown, the network architecture can include a first device 101 and a second device 102, and a wireless connection can be established between the first device 101 and the second device 102 for wireless communication, for example, communication can be established through Bluetooth, UWB, NFC, WIFI or cellular.

[0100] The first device 101 can be an entity for transmitting or receiving signals, and communicates with the second device 102 in a wireless network. The first device 101 is exemplarily illustrated by taking a car as an example in the Figure 1 The first device 101 can also be a motorcycle, a ship, an airplane, a smart home, etc.

[0101] The second device 102 can be an electronic device, for example, an entity for receiving or transmitting signals on the user side, such as a terminal device, a user equipment, an access device, and the like. The user equipment is a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a wearable device, and the like.

[0102] By way of example and not limitation, in the embodiments of the present application, the wearable device can also be referred to as a wearable smart device, which is a general term for devices that are designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing, and shoes. The wearable device is a portable device that is directly worn on the body or integrated into the clothes or accessories of the user. The wearable device is not only a hardware device, but also a device that realizes powerful functions through software support and data interaction and cloud interaction.

[0103] In the embodiments of the present application, the data verification of the first device and the second device can be added on the basis of the RSSI ranging technology to evaluate whether the first device and the second device are subjected to a broadcast relay attack in the communication process, so as to improve the unlocking security of the first device, and further improve the reliability of the non-contact intelligent access system and reduce the risk of the to-be-unlocked device encountering a broadcast relay attack. The technical solution does not depend on the Internet and a satellite positioning system such as GPS, can be used when the first device and the second device are both offline, and does not need the user to perform an active authentication process such as a gesture operation, so the applicability of the technical solution is strong, and the user can obtain a better use experience.

[0104] The unlocking method provided in the embodiments of the present application will be described in detail below.

[0105] Please refer to Figure 2 , Figure 2 is a flowchart of an unlocking method provided in the embodiments of the present application. The method is described by taking the first device as the execution subject. The first device in the embodiments of the present application can be the first device 101 in the network architecture shown in Figure 1 The functions performed by the first device in the embodiments can also be performed by a device (for example, a chip, or a chip system, or a circuit) in the first device. The second device in the embodiments of the present application can be the second device 102 in the network architecture shown in Figure 1 The functions performed by the second device in the embodiments can also be performed by a device (for example, a chip, or a chip system, or a circuit) in the second device. As shown in Figure 2As shown, the unlocking method can include at least the following steps.

[0106] S201: Obtain an RSSI value of a signal sent by the second device, the RSSI value being used to calculate a distance between the first device and the second device.

[0107] The first device can periodically send a beacon message and wait for the second device to perform authentication connection. After the first device and the second device perform security authentication, a wireless communication connection can be established, for example, the first device and the second device can establish communication through Bluetooth, UWB, NFC, WIFI or cellular.

[0108] Since the signal strength and the distance have a linear relationship, the RSSI value can be used to calculate the distance between the signal sending end and the receiving end. The first device can obtain the RSSI value of the signal sent by the second device, and calculate the distance between the two devices through the RSSI value.

[0109] S202: In a case where the distance is less than a preset distance, obtain first information of the first device and second information of the second device.

[0110] The first device can determine whether the distance between the two devices is less than a preset distance. If yes, the first device can obtain the first information of the first device and the second information of the second device, otherwise, the RSSI ranging in step S201 can be continued.

[0111] The first information can include at least one of an atmospheric pressure value of a position where the first device is located, a first real-time position of the second device, a first real-time speed of the second device and a first real-time acceleration of the second device. The second information can include at least one of an atmospheric pressure value of a position where the second device is located, a second real-time position of the second device, a second real-time speed of the second device and a second real-time acceleration of the second device.

[0117] After the first device acquires the first information of the first device and the second information of the second device, it can be determined whether the first information and the second information satisfy a preset condition. It can be understood that the satisfaction of the preset condition herein can mean that the first information and the second information comprise the same information in part or in whole.

[0118] S204: unlocking.

[0119] In the case where the first information and the second information satisfy the preset condition, unlocking is performed. The unlocking of the first device in the embodiment of the application can also be understood as the intelligent entering of the first device, the intelligent entering of the first device, the entering of the first device, etc.

[0120] In a possible implementation manner, an electronic control unit (ECU) can be used to drive the door lock to perform the unlocking action.

[0122] In the case where the first information and the second information do not satisfy the preset condition, the first device can reject unlocking and send an alarm signal. Here, the sending of the alarm signal can be to the second device, or to the cloud, and then sent to the second device by the cloud, which is not limited in the application.

This improves the unlocking security of the first device, thereby enhancing the reliability of the contactless smart entry system and reducing the risk of broadcast relay attacks on the device to be unlocked. Furthermore, this technical solution does not rely on the internet or satellite positioning systems such as GPS, allowing it to be used when both the first and second devices are offline. It also eliminates the need for active authentication processes such as user gestures, making it highly applicable and providing a better user experience.
