Abstract

The invention provides a data processing method based on a virtual private network. The data processing method includes: receiving data sent by the virtual private network through a safe application with a VPN supporting tool; during data storing, using a secret key to encrypt the data by the safe application; during data reading, using a secret key to decrypt the data by the safe application. The data before being stored are encrypted by the safe application with the VPN supporting tool, so that the data can be checked correctly only through data decryption by the safe application, and safety after enterprise data are sent to a terminal is guaranteed. In addition, the invention provides a data processing device based on the virtual private network.

Description

technical field [0001] The invention relates to the field of network security, in particular to a virtual private network-based data processing method and device. Background technique [0002] With the development of VPN (Virtual Private Network, virtual private network) technology, it is possible to establish a private network on a public Internet network, encrypt and transmit private information through a VPN channel, and users can use mobile terminals to access corporate intranet resources through VPN to Work remotely. [0003] When a user accesses an enterprise's internal resources through a mobile terminal, it first accesses the enterprise's intranet through a VPN, and then accesses it through an APP (Application, application software) or browser. The communication process is encrypted and transmitted through a VPN to ensure that the data Not to be monitored and tampered with. Since the current VPN device only has the communication encryption function, it can only gua...
