It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
In order to solve the problems in the prior art, embodiments of the present application provide a vehicle unlocking method, a vehicle end, a vehicle, an electronic device, and a readable storage medium. The following first describes a vehicle unlocking method provided in the embodiment of the present application.
Fig. 1 shows a flow chart of a vehicle unlocking method according to an embodiment of the present application. As shown in fig. 1, the vehicle unlocking method may include:
In step 101, a first terminal may register on a vehicle end, and generate user registration information of the first terminal. When the vehicle end receives an unlocking request of the first terminal, the cloud server adds a random number, and the random number and user registration information of the first terminal can generate a first key corresponding to the first terminal and send the first key to the vehicle end. Namely, the vehicle end can acquire a first key K1 corresponding to the first terminal, and the vehicle end can also acquire a second key K2 corresponding to the vehicle end, wherein the second key K2 can be a preset key when the vehicle leaves the factory.
In step 102, a real-time key may be generated by a hash algorithm according to the first key, the second key, and the first current time information of the vehicle end. For example, the real-time key may be generated by directly hashing the first key, the second key, and the first current time information. The method can also be that the second key and the first current time information are subjected to hash operation once, the obtained hash value is synthesized with the first key, and the synthesized key is subjected to hash operation with the first current time information again to generate the real-time key. The specific generation algorithm of the real-time key can be set according to actual requirements, and is not particularly limited herein.
And step 103, receiving an unlocking key sent by the first terminal, wherein the unlocking key is generated according to the first key, the second key and the second current time information of the first terminal.
In step 103, an unlock key sent by the first terminal may be received, where the unlock key may be carried in the unlock request, or the unlock key may be sent to the vehicle end after the first terminal sends the unlock request to the vehicle end. The unlocking key is generated according to the first key, the second key and the second current time information of the first terminal. It can be appreciated that the unlocking key generation algorithm is the same as the real-time key generation algorithm to ensure that the two can be matched.
In step 104, the real-time key and the unlock key may be compared, and if they are identical, the real-time key may be considered to be matched with the unlock key, and at this time, the vehicle end may return a confirmation password, and execute the vehicle unlock operation through the unlock request and in response to the unlock request.
In the embodiment of the application, the vehicle unlocking method can acquire the first key corresponding to the first terminal and the second key corresponding to the vehicle end under the condition that the first terminal is registered at the vehicle end and an unlocking request of the first terminal is received; generating a real-time key according to the first key, the second key and the first current time information of the vehicle end; receiving an unlocking key sent by a first terminal, wherein the unlocking key is generated according to the first key, the second key and second current time information of the first terminal; in case the real-time key matches the unlocking key, the unlocking request is passed. Therefore, the real-time secret key of the vehicle end is generated according to the first secret key corresponding to the first terminal, the second secret key corresponding to the vehicle end and the first current moment information of the vehicle end, namely the real-time secret key can change along with different time, the risk of vehicle theft is reduced, and the safety of vehicle unlocking is improved.
In some embodiments, the step 102 may include:
carrying out hash operation on the second secret key and the first current time information of the vehicle end to generate a third secret key;
synthesizing an authentication key according to the third key and the first key;
and carrying out hash operation on the verification key and the first current time information to generate a real-time key.
In this embodiment, the second key and the first current time information of the vehicle end may be hashed to generate a third key, then the third key and the first key are synthesized to obtain an authentication key, and finally the authentication key and the first current time information are hashed again to generate a real-time key.
Therefore, the first current moment information is utilized to carry out hash operation twice, so that a real-time key generation algorithm is more complex, the risk of vehicle theft is further reduced, and the safety of vehicle unlocking is improved.
In some embodiments, the generating the third key by performing a hash operation on the second key and the first current time information of the vehicle side may include:
carrying out hash operation on the second key and first time level information corresponding to the first current time information to generate a third key;
the generating the real-time key by performing the hash operation on the verification key and the first current time information may include:
performing hash operation on the verification key and second time-level information corresponding to the first current time information to generate a real-time key;
wherein the first time level information is greater than the second time level information.
In this embodiment, the first time level information may be greater than the second time level information, for example, the first time level information may indicate an hour, and the second time level information may indicate a minute, for example, 8:20 corresponds to 8 for the first time level information and 20 for the second time level information.
The second key and the first time level information corresponding to the first current time information may be hashed to generate a third key. At this time, the third key is the first time-level information key, and taking the hour indicated by the first time-level information as an example, the calculation formula of the third key S1 may be as shown in formula (1):
S1＝Hash(K2，Th) (1)
wherein S1 is a third key, hash is a Hash algorithm, K2 is a second key, and Th is hour level information.
The calculation formula of the verification key S2 may be as shown in formula (2):
S2＝S1+K1 (2)
wherein S2 is the authentication key, S1 is the third key, and K1 is the first key.
The verification key and the second time-level information corresponding to the first current time information can be subjected to hash operation to generate a real-time key. At this time, the real-time key is a second time-level information key, and taking the second time-level information indicating the minute as an example, the calculation formula of the real-time key S3 may be as shown in formula (3):
S3＝Hash(S2，Tm) (3)
wherein S3 is a real-time key, hash is a Hash algorithm, S2 is a verification key, and Tm is minute-level information.
In this way, the first time level information key can be determined through the first hash algorithm, and the second time level information key is determined through the second hash algorithm based on the first time level information key, so that the real-time key generation algorithm is more complex, the risk of vehicle theft is further reduced, and the safety of vehicle unlocking is improved.
In some embodiments, the vehicle unlocking method may further include:
receiving an unlocking request of a second terminal, wherein the unlocking request of the second terminal carries a sharing key, the sharing key is synthesized by the second terminal according to a fourth key and a first key which are shared by the first terminal, the fifth key and second time-level information corresponding to third current time information of the second terminal are subjected to hash operation generation, the fourth key is generated based on hash operation of the second key and first time-level information corresponding to a key sharing time period, and the key sharing time period is determined based on the sharing operation received by the first terminal;
acquiring a first key corresponding to a first terminal and a second key corresponding to a vehicle end;
carrying out hash operation on the second key and first time level information corresponding to the first current time information to generate a third key;
synthesizing an authentication key according to the third key and the first key;
performing hash operation on the verification key and second time-level information corresponding to the first current time information to generate a real-time key;
and in the case that the real-time key is matched with the sharing key, passing the unlocking request.
In this embodiment, since the real-time key is a verification key synthesized based on the first time-level information key (third key) and the first key, hash operation generation is performed again with the second time-level information, and the unlock key is identical to the generation algorithm of the real-time key. Based on the above, the first terminal may enable the second terminal to unlock the vehicle temporarily by sharing the first time-level information key and the first key.
For example, as shown in fig. 2, a user may set a key sharing period on the first terminal, and the cloud server may generate a fourth key according to the first time level information and the second key corresponding to the key sharing period, where a generation algorithm of the fourth key is shown in formula (1). The first terminal may share the fourth key and the first key to the second terminal.
The second terminal may synthesize a fifth key according to the fourth key and the first key shared by the first terminal, where a generation algorithm of the fifth key is shown in formula (2). And carrying out hash operation on the second time-level information corresponding to the third current time information of the second terminal and the fifth key to generate a shared key, wherein the generation algorithm of the shared key is shown in a formula (3).
And the second terminal can send an unlocking request to the vehicle end according to the sharing key. After receiving the unlocking request of the second terminal, the vehicle end can acquire a first key corresponding to the first terminal and a second key corresponding to the vehicle end, hash the second key and first time level information corresponding to the first current time information to generate a third key, synthesize a verification key according to the third key and the first key, hash the verification key and second time level information corresponding to the first current time information to generate a real-time key. And comparing the real-time key with the sharing key, and if the real-time key and the sharing key are consistent, considering that the real-time key is matched with the sharing key, and at the moment, unlocking the vehicle by an unlocking request.
It is understood that the second terminal may be a different terminal than the first terminal, or may be the first terminal. For example, in some situations (such as an underground parking garage) where there is no network or a network signal is poor, the unlocking key issued by the cloud server may not be received due to the inability to network connection, and at this time, the second terminal may perform hash operation on itself based on the fourth key and the first key acquired previously, so as to generate the sharing key to unlock the vehicle.
In some embodiments, the step 102 may include:
and generating a real-time key according to the first key, the second key, the first current time information of the vehicle end and the error time information.
It can be understood that, due to system redundancy in the process of generating the real-time key by the vehicle end, or due to inconsistent time between the vehicle end and the first terminal, the real-time key and the unlocking key are not matched due to time errors, so that unlocking cannot be performed.
Based on this, in this embodiment, the real-time key may be generated according to the first key, the second key, the first current time information of the vehicle end, and the error time information. The error time information may be preset according to an empirical value or may be obtained by a pre-test. Therefore, when the real-time key is generated, error time information can be considered to ensure the accuracy of the real-time key, so that the success rate of unlocking the vehicle is improved.
In some embodiments, before the generating the real-time key according to the first key, the second key, the first current time information of the vehicle end and the error time information, the vehicle unlocking method may further include:
generating a plurality of preset keys according to the first key, the second key and a plurality of preset time information, wherein the plurality of preset time information is time information in a system redundancy time period of the last time information of the vehicle end;
receiving a sixth key sent by the first terminal, wherein the sixth key is generated according to the first key, the second key and the last time information of the first terminal;
matching the sixth key with a plurality of preset keys to determine a target key, wherein the target key is a preset key matched with the sixth key in the preset keys;
and determining error time information according to preset time information corresponding to the target key.
In this embodiment, a plurality of time information (i.e., a plurality of preset time information) in a system redundancy time period of the last time information of the vehicle end may be acquired first, where a time range of the plurality of preset time information may be [ T- Δt, t+Δt ], where T is the last time information, and Δt is the system redundancy time period and may be set according to an empirical value.
The plurality of preset keys may be generated according to the first key, the second key, and the plurality of preset time information. The algorithm for generating the plurality of preset keys is as described above, and will not be described herein.
The sixth key sent by the first terminal may be received, and the sixth key may be generated according to the first key, the second key, and the previous time information of the first terminal, where a generation algorithm of the sixth key is consistent with a generation algorithm of the plurality of preset keys.
The sixth key may be compared with a plurality of preset keys, a target key that matches the sixth key may be determined, and error time information may be determined according to preset time information corresponding to the target key. For example, a difference between preset time information corresponding to the target key and previous time information of the vehicle end may be determined as the error time information.
Therefore, the sixth key can be matched with a plurality of preset keys before the real-time key is generated, so that error time information is obtained through testing, the accuracy of the error time information is guaranteed, the accuracy of the subsequent real-time key generation is improved, and the success rate of vehicle unlocking is improved.
