Abstract

The disclosure relates to a data transmission method and device. The method comprises the following steps: acquiring a unique identifier and a private key of a data transmitting end, and a public key of a data receiving end; encrypting first data to be transmitted by using the public key of the data receiving end to obtain encrypted second data; signing the second data by using the private key of the data transmitting end to obtain a first signature value; generating a random character string including current time; signing the second data, the first signature value and the random character string by using the unique identifier of the data transmitting end to obtain a third signature value; and transmitting the second data, the first signature value, the random character string and the third signature value to the data receiving end. Through adoption of the data transmission method and device, the data security in a data transmission process is enhanced.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a data transmission method and device. Background technique [0002] In related technologies, mobile phones record various information of users, such as contacts, photos, text messages, call records, and security tools. . [0003] In order to prevent the loss of the mobile phone, the manufacturer added the remote retrieval function to the mobile phone, and in order to protect the personal privacy and property safety of the lost person, added functions such as remote locking and remote erasing. In this process, the participation of a third party is required. Such as operators or application providers with mobile phone loss prevention functions. Contents of the invention [0004] Embodiments of the present disclosure provide a data transmission method and device to improve data security during data transmission. [0005] According to a first aspect of an...
