When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

A method of sharing a digital car key in CCC (Car Connectivity Consortium, internet of vehicles alliance) specifications may include the steps of:

firstly, the owner side equipment determines the URL address for sharing the digital car key through the brand server corresponding to the owner side equipment.

Wherein the URL address is an address on an intermediate server, including but not limited to a vehicle factory server, where the digital vehicle key is stored.

And secondly, the URL address can be sent to the equipment to be shared by the main equipment through a short message, a WeChat or other instant messaging modes.

And finally, the equipment to be shared can find the intermediate server through the URL address, so that the digital car key shared by the equipment at the car owner end is obtained.

In the embodiment of the present disclosure, the URL address includes a prkey field, where the prkey field indicates a key of the digital car key, and the interaction process may be shown in fig. 1A.

In addition, the disclosure further provides another method for sharing a digital car key, referring to fig. 1B, including the following steps:

in step 101, the host device creates a temporary mailbox on the relay server.

The temporary mailbox is used for storing the encrypted digital car key.

In step 102, the owner device sends the temporary mailbox address and the key on the relay server to the device to be shared through a URL address.

In step 103, the device to be shared accesses the temporary mailbox through the URL address, and obtains the digital car key through decryption of the key.

In step 104, the device to be shared deletes the temporary mailbox after obtaining the decrypted digital car key.

In the above mode, the URL address includes the key corresponding to the digital car key, and there is a risk of interception by other devices, so that the security is poor. In order to solve the technical problems, the present disclosure provides the following method for sharing a digital car key.

The method for sharing the digital car key provided by the present disclosure is described first from the side of the car owner's end device.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for sharing a digital car key according to an exemplary embodiment of the present disclosure, where the method for sharing a digital car key may include the following steps, where the main device may be a terminal device used by a vehicle owner, and the terminal device includes, but is not limited to, a mobile phone, a notebook computer, a desktop computer, an ipad, etc., as shown in fig. 2:

In step 201, a URL address of a URL used for sharing the digital car key is sent to a device to be shared through a first message.

In the embodiment of the disclosure, the terminal device to be shared may be a friend terminal device desiring to obtain a digital car key from a car owner terminal device. Wherein, the URL address does not include the key corresponding to the digital car key.

In one possible implementation, the message type of the first message may be a micro message or a short message or other message type of instant messaging.

In step 202, security information corresponding to the digital car key is sent to the device to be shared through a second message.

In one possible implementation manner, the message type of the second message may be the same as the message type of the first message, so that the possibility that other devices intercept the URL address and the security information at the same time is reduced, and thus the security of sharing the digital car key is improved. For example, the message type of the first message is a micro message or a short message or other message types of instant messaging, and the message type of the second message may also be a micro message or a short message or other message types of instant messaging.

In another possible implementation manner, the message type of the second message may be different from the message type of the first message, and compared with the case that the message type of the second message may be the same as the message type of the first message, the possibility that other devices intercept the URL address and the security information at the same time may be further reduced, so that the security of sharing the digital car key is improved.

For example, the message type of the first message is a WeChat, and the message type of the second message may be a short message or voice. For another example, if the message type of the first message is a sms, the message type of the second message may be a sms or voice. Under the condition that the message type is voice, the user of the vehicle owner side equipment can inform the safety information to the user of the equipment to be shared in a telephone voice or WeChat voice mode.

In the embodiment of the present disclosure, the security information may be information for protecting the security of the digital car key.

In one possible implementation, the security information may be a key that encrypts or decrypts the digital car key.

In another possible implementation, the security information may be a password used to generate the key.

In another possible implementation, the security information may be other information for securing a digital car key, which is not limited by the present disclosure.

In addition, the present disclosure does not limit the execution sequence of the step 201 and the step 202, and the step 201 may be executed first, then the step 202 may be executed, or the step 202 may be executed first, then the step 201 may be executed.

In the embodiment, the vehicle owner device can respectively send the URL address for sharing the digital vehicle key and the key corresponding to the digital vehicle key to the device to be shared through two different messages, so that the risk that the URL address and the key are intercepted by other devices except the device to be shared is reduced, and the security of sharing the digital vehicle key is improved.

In some alternative embodiments, referring to fig. 3A, fig. 3A is a flowchart of a method for sharing a digital car key according to an exemplary embodiment of the disclosure, where the method may be applied to a host device, and the security information is a key for encrypting or decrypting the digital car key, and the method includes the following steps:

in step 301, a digital car key is encrypted based on a key.

In the embodiment of the disclosure, the digital car key can be encrypted by the digital key framework of the car owner end device based on the key.

In step 302, the encrypted digital car key is sent to the designated server.

In the embodiment of the disclosure, the digital key frame of the vehicle owner device may send the encrypted digital vehicle key to the designated server. The specified server may be a trusted third party server or a relay server as a relay, which is not limited in this disclosure.

In one possible implementation, the designated server is a third party server, and the owner device may send the encrypted digital car key to a brand server corresponding to the owner device, where the brand server forwards the encrypted digital car key to the third party server.

In another possible implementation manner, the designated server is a relay server, the owner device may establish a temporary mailbox on the relay server, send the encrypted digital car key to the relay server, and store the encrypted digital car key in the temporary mailbox by the relay server.

In step 303, a URL address corresponding to the encrypted digital car key is determined.

The URL address is used for indicating the access address of the encrypted digital car key on the appointed server.

In one possible implementation, the URL address is used to indicate the address on the designated server where the encrypted digital car key is stored.

In another possible implementation, the URL address is used to indicate a temporary mailbox address on the designated server corresponding to the encrypted digital car key.

In step 304, the URL address for sharing the digital car key is sent to the device to be shared through the first message.

In step 305, a key corresponding to the digital car key is sent to the device to be shared through a second message.

In one possible implementation manner, the message type of the second message may be the same as the message type of the first message, so that the possibility that other devices intercept the URL address and the security information simultaneously is reduced, thereby improving the security of sharing the digital car key. For example, if the message type of the first message is a sms or a sms, the message type of the second message may also be a sms or a sms.

In another possible implementation manner, the message type of the second message may be different from the message type of the first message, and compared to the case where the message type of the second message may be the same as the message type of the first message, the possibility that other devices intercept URL addresses and security information at the same time may be further reduced, so that security of sharing the digital car key is improved.

For example, the message type of the first message is a WeChat, and the message type of the second message may be a short message or voice. For another example, if the message type of the first message is a sms, the message type of the second message may be a sms or voice. Under the condition that the message type is voice, the user of the vehicle owner side equipment can inform the key to the user of the equipment to be shared in a telephone voice or WeChat voice mode.

The present disclosure does not limit the execution sequence of the step 304 and the step 305, and the step 304 may be executed first, then the step 305 may be executed, or the step 305 may be executed first, then the step 304 may be executed.

In the embodiment, the owner side equipment can firstly generate the secret key through the password and encrypt the digital car key through the secret key, so that the convenience and safety of sharing the digital car key are improved.

in step 301', a key corresponding to a digital car key is generated by means of a password.

In the embodiment of the disclosure, considering that the key is generally longer, the user of the device to be shared is difficult to remember, and also difficult to input the key once and completely when the key is required to be input, the copying process is also troublesome, and in order to improve the convenience of the user of the device to be shared in acquiring the digital car key, the key corresponding to the digital car key can be replaced by the password which is shorter in length and easy to memorize.

In one possible implementation, the password may be determined by one of a number, letter, symbol, or a combination of a plurality of numbers, letters, symbols. Wherein the digits include, but are not limited to, arabic numerals, the letters include, but are not limited to, uppercase English letters, lowercase English letters, or letters corresponding to other languages, and the symbols include, but are not limited to, underlines, horizontal lines, separators, and the like.

It will be appreciated that the password setting rules in the present disclosure may be existing common password setting rules, which are not limited in this disclosure.

In another possible implementation, the key is generated by a DK frame work (Digital Key framework, digital key frame) of the host end device by a password.

In another possible implementation, the owner device may generate the key based on a specified algorithm or a specified protocol through the password and the target parameter.

Wherein the target parameter is a parameter corresponding to the specified algorithm or the specified protocol, the specified algorithm including but not limited to a spak2+ algorithm, the specified protocol including but not limited to an SRP (Secure Remote Password, secure remote key) protocol.

In the embodiment of the disclosure, the target parameters can be pre-agreed by the owner device and the sharing device. When the key is required to be generated, the digital key framework of the vehicle owner terminal equipment generates the key corresponding to the digital vehicle key according to a specified algorithm or a specified protocol through the password and the target parameter.

Taking the designated algorithm as a spak2+ algorithm as an example, the master device may pre-agree with target parameters corresponding to the spak2+ algorithm with the to-be-shared device, where the target parameters include, but are not limited to, at least one of the following: ECC (Ellipse Curve Cryptography, elliptic curve code) elliptic curve parameters, salt, cost parameter Nscrypt, block size r, parallelization parameter p, output length dkLen, etc. The digital key frame of the main terminal equipment can calculate and obtain the key according to the target parameter and the password and the spak2+ algorithm.

In step 302', the digital car key is encrypted based on the key.

In step 303', the encrypted digital car key is transmitted to the designated server.

In step 304', the URL address corresponding to the encrypted digital car key is determined.

In step 305', the URL address for sharing the digital car key is sent to the device to be shared through the first message.

In one possible implementation, the message type of the first message may be a WeChat or a SMS.

In step 306', the password is sent to the to-be-shared terminal device through a second message.

For example, the message type of the first message is a WeChat, and the message type of the second message may be a short message or voice. For another example, if the message type of the first message is a sms, the message type of the second message may be a sms or voice. Under the condition that the message type is voice, the user of the vehicle owner side equipment can inform the password to the user of the equipment to be shared in a telephone voice or WeChat voice mode.

The present disclosure does not limit the execution sequence of the step 305 'and the step 306', and the step 305 'may be executed first, then the step 306' may be executed, or the step 306 'may be executed first, then the step 305' may be executed.

In some alternative embodiments, the owner side device may also directly send the unencrypted digital car key and the key generated by the password to the designated server, where the designated server encrypts the digital car key by using the key, and sends the URL address of the encrypted digital car key to the owner side device.

And the owner side equipment sends the URL address to the equipment to be shared through the first message, and sends the secret key to the equipment to be shared through the second message. The purpose of improving the safety of sharing the digital car key can be achieved.

In some alternative embodiments, referring to fig. 4, fig. 4 is a flowchart of a method for sharing a digital car key according to an exemplary embodiment of the disclosure, where the method may be applied to a host device, and includes the following steps:
