Embodiment 1

[0035] An embodiment of the present application provides a data synchronization method applied to a first electronic device, figure 1 A flow chart of a data synchronization method provided by an embodiment of the present application is shown. Such as figure 1 As shown, the data synchronization method provided by the embodiment of the present application may include the following steps 201 to 203 .

[0036] Step 201, the first electronic device encrypts first data to be sent to obtain target data.

[0037] In the embodiment of this application, the user can select a random number (such as the first random number) in the elliptic curve group as the user's private key (Secret Key, sk) of the first electronic device, so as to trigger the first electronic device to sk, using a preset formula: D=sk*G, performing initial calculations on data, wherein G is an elliptic curve generator, and the generator is a point; thus the first electronic device can use a hash algorithm (such as Ha...

Embodiment 2

[0083] The embodiment of the present application provides a data synchronization method applied to the first server, figure 2 A flow chart of a data synchronization method provided by an embodiment of the present application is shown. Such as figure 2 As shown, the data synchronization method provided by the embodiment of the present application may include the following steps 401 and 402 .

[0084] Step 401, the first server acquires target data, a first digital signature and a second digital signature.

[0085] In the embodiment of the present application, the above-mentioned target data is the encrypted data of the first data to be sent by the first electronic device, and the above-mentioned first digital signature is based on the target data and the first user identifier of the first electronic device by the first electronic device and the first service identifier of the first electronic device, and the second digital signature is generated by the first electronic devi...

Embodiment 3

[0119] The embodiment of the present application provides a data synchronization method applied to the second server, image 3 A flow chart of a data synchronization method provided by an embodiment of the present application is shown. Such as image 3 As shown, the data synchronization method provided by the embodiment of the present application may include the following steps 701 and 702 .

[0120] Step 701, the second server acquires the target data, the third digital signature and the fourth digital signature.

[0121] In this embodiment of the present application, the target data is the encrypted first data to be sent by the first electronic device, and the third digital signature is the first server based on the first user identifier of the first electronic device, the first electronic device's The first service identifier, the second service identifier of the second electronic device and the target data are generated, and the fourth digital signature is generated by t...

Abstract

The invention discloses a data synchronization method and electronic equipment, and belongs to the field of communication. Encrypting to-be-sent first data to obtain target data; generating a first digital signature based on the target data, a first user identifier of the first electronic equipment and a first service identifier of the first electronic equipment, and sending the first digital signature and the target data to a first server; generating a second digital signature based on the first user identifier, the first service identifier and a second service identifier of the second electronic device, and sending the second digital signature to the first server; whether the first server sends the target data to the second electronic device or not is verified through the first digital signature and the second digital signature.

Description

technical field [0001] The present application belongs to the communication field, and in particular relates to a data synchronization method and electronic equipment. Background technique [0002] At present, electronic devices usually store user data in cloud servers of different service providers. When users need to synchronize data between two electronic devices (for example: device A and device B), the user key can be escrowed in In the cloud server, the cloud server is not encrypted, so that when the electronic device performs data synchronization, it can directly use the user key in the cloud server to complete user identity authentication, so as to synchronize data from the cloud server of device A to the cloud of device B. in the server. [0003] However, for the above solution, if the cloud server is attacked, resulting in security risks of the cloud server, user data (for example: sensitive data) may be at risk of leakage. In this way, the security of the electr...
