A bluetooth key acquisition method, apparatus, device, and storage medium of a vehicle according to an embodiment of the present application will be described below with reference to the accompanying drawings. Specifically, fig. 1 is a flowchart illustrating a method for acquiring a bluetooth key of a vehicle according to an embodiment of the present application.
The method for obtaining the bluetooth key of the vehicle shown in fig. 1 is applied to a mobile terminal, for example, a mobile terminal of an IOS operating system (IOS is a handheld device operating system developed by apple, inc.), an Android operating system (Android system is an operating system based on Linux, free and open source codes), and a Windows Phone operating system (Windows Phone is a mobile Phone operating system issued by microsoft), and certainly, the method may also be a personal computer and other intelligent mobile terminals, which is not limited in the embodiment of the present application. The method comprises the following steps:
in step S101, a bluetooth key acquisition request of the target vehicle is transmitted to the server.
In step S102, an encryption key sent by the server is received, where the encryption key is obtained by the server by generating a bluetooth key of the target vehicle according to the bluetooth key acquisition request and then encrypting the generated bluetooth key with a public key of the mobile terminal.
It will be appreciated that, after the server receives the acquisition request, the key management unit of the server: and the Bluetooth key is responsible for generating the Bluetooth key and issuing the Bluetooth key to the mobile terminal and the vehicle terminal, wherein the Bluetooth key is a cipher text generally. Simultaneously, the server sends for mobile terminal after encrypting the bluetooth key, because the bluetooth key is in the encryption state, consequently can effectively avoid being cracked the robbery, promotes the security of bluetooth key transmission.
In the embodiment of the present application, before receiving the encryption key sent by the server, the method includes: when the server generates the Bluetooth key of the target vehicle according to the Bluetooth key acquisition request, an asymmetric encryption key pair is generated through a preset safety container, and a public key in the key pair is sent to the server.
The preset safety container can be specifically arranged according to actual requirements and is not specifically limited.
It can be understood that, this application embodiment can generate the key pair through the secure container, takes the encrypted key from the server under the network condition, uses the secure container to save the key, promotes the security of bluetooth key.
Specifically, the mobile terminal is provided with a secure container unit, which is used for generating an asymmetric encrypted key pair through the secure container when the server generates the key, and the key pair is stored in the secure container. And returning the public key to the server, encrypting the Bluetooth key by using the public key by the server, and then returning the encrypted key to the mobile terminal.
In step S103, the encryption key is decrypted by using its own private key to obtain the bluetooth key of the target vehicle, and the target vehicle communicates with the bluetooth key.
It can be understood that, this application embodiment can just obtain real bluetooth key through the deciphering when using, need not online security authentication, can be under the off-line scene safe use bluetooth key, effectively promotes bluetooth key's suitability, improves user's use and experiences.

In this embodiment of the application, decrypting the encryption key with its own private key to obtain the bluetooth key of the target vehicle further includes: acquiring a private key and an encryption key in a key pair stored in a preset safety container; and decrypting the encrypted key by using a private key in the key pair to obtain the Bluetooth key of the target vehicle.
It can be understood that, when the embodiment of the application is used in an off-line scene, the key is taken out from the safety container to decrypt the stored bluetooth key to obtain a truly usable bluetooth key, and the security of bluetooth communication can be ensured through the bluetooth key taken out from the safety container unit without on-line security authentication.
Specifically, the key cryptogram is also stored inside the secure container unit of the activation terminal. When the Bluetooth key is used offline, the mobile terminal decrypts the encrypted key by using the private key corresponding to the security container without participation of a server side, obtains a real Bluetooth key, and can communicate with a vehicle side.
Because the encrypted key is stored in the mobile terminal in a persistent manner and is put into the APP process, the step is at risk of being cracked, and if the mobile terminal or the APP is cracked, an attacker can take the file for storing the key. But it is not risky for an attacker to get to the encrypted key because decryption is required before use.

The keying material is bound to secure hardware of the Android device, such as a Trusted Execution Environment (TEE) and a Secure Element (SE). When this function is enabled for the key, its keying material is never exposed outside the secure hardware.
An Application Programming Interface (API) provided by android keystore may directly generate a key pair, obtain the key under the security condition of the Application process, and use this mechanism to securely store and decrypt the private key of the bluetooth key. In actual use, the stored key ciphertext is decrypted, and the real key is taken to carry out Bluetooth communication.
The stored secret key is generated by the APP security container, and the stored encrypted Bluetooth key is generated by the cloud. The key generation needs the participation of the cloud, and even if the cloud does not participate in the subsequent off-line use process, the safety of the Bluetooth communication can be ensured through the Bluetooth key taken by the safety container unit.
According to the method for acquiring the Bluetooth key of the vehicle, the encrypted Bluetooth key can be acquired from the server, and the Bluetooth key is in an encrypted state when the mobile terminal stores the encrypted Bluetooth key, so that the encrypted Bluetooth key can be effectively prevented from being decrypted and stolen, the safety of the Bluetooth key is improved, a real Bluetooth key can be obtained through decryption when the encrypted Bluetooth key is used, online safety authentication is not needed, the Bluetooth key can be safely used in an offline scene, the applicability of the encrypted Bluetooth key is effectively improved, and the use experience of a user is improved; the secret key pair can be generated through the safety container, the encrypted key is taken from the server under the condition of networking, the secret key is stored by using the safety container, and the safety of the Bluetooth key is improved; when the Bluetooth key decryption device is used in an offline scene, the secret key decryption stored Bluetooth key is taken out from the safety container to obtain a real available Bluetooth key, online safety authentication is not needed, and safety of Bluetooth communication is guaranteed through the Bluetooth key taken by the safety container unit.
