Embodiment 1

[0034] figure 1 It is a schematic structural diagram of a digital key generation system provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of generating a digital key for a vehicle. The method can be executed by the digital key generation system. The system can use hardware and / or or software, see figure 1 , the digital key generation system implemented in the present invention specifically includes: a client 101 , a private cloud 102 and a public cloud 103 .

[0035] The client 101 is used for uploading vehicle encrypted information to the private cloud 102 and obtaining the digital key issued by the private cloud 102 .

[0036] Wherein, the client 101 may be an intelligent terminal for storing the digital key and unlocking the vehicle according to the digital key. Application software may be installed in the client 101 to support the digital key to unlock the vehicle, and the vehicle encryption information may be used to generate th...

Embodiment 2

[0046] figure 2 It is a schematic structural diagram of a digital key generation system provided by Embodiment 2 of the present invention. The embodiment of the present invention is based on the above-mentioned embodiments. See figure 2 , the digital key generation system provided by the embodiment of the present invention includes: a client 201 , a private cloud 202 and a public cloud 203 . The client 201 is used for uploading vehicle encrypted information to the private cloud 202 and obtaining the digital key issued by the private cloud 202 . The private cloud 202 is used to generate a primary key according to the vehicle encryption information uploaded by the client 201, and encrypt the primary key according to the white box key issued by the public cloud 203 to generate a digital key. The public cloud 203 is configured to generate a white-box key according to the key number of the primary key uploaded by the private cloud 202 .

[0047] The private cloud 202 acquires t...

Abstract

The invention discloses a digital key generation system. The system comprises a client, a private cloud and a public cloud, the client is used for uploading vehicle encryption information to the private cloud and acquiring a digital key issued by the private cloud; the private cloud is used for generating a primary key according to the vehicle encryption information uploaded by the client, and encrypting the primary key according to a white box key issued by the public cloud to generate a digital key; and the public cloud is used for generating a white box key according to the key number of the primary key uploaded by the private cloud. According to the technical scheme provided by the embodiment of the invention, the digital key generation process is jointly realized by the private cloudand the public cloud, and the private data of the user is only processed at the private cloud, so that the private data is prevented from being leaked, and the safety of the digital key generation process is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of information security, in particular to a digital key generation system. Background technique [0002] With the rapid development of vehicle information technology, digital keys are gradually replacing traditional mechanical keys, remote keys and smart keys. Through the digital key, the connection with the vehicle Bluetooth can be realized, and functions such as identity verification, vehicle positioning and vehicle control can be realized. Since the digital key contains vehicle information privacy data, the information use and data transmission of the digital key play a decisive role in vehicle safety. [0003] When the existing technology generates a digital key, the encryption process of the digital key is implemented in the public cloud, and private data including users, vehicles, and Bluetooth modules need to be uploaded to the public cloud, and there is a risk of leakage of...
