Embodiment Construction

[0014] The present invention will be described in detail below in combination with specific embodiments.

[0015] The present invention as figure 1 Shown is the working principle diagram of encrypted VPN for traffic classification. The VPN client classifies the smart terminal traffic through the traffic classifier, and divides it into text data and non-text data, and performs strong encryption and compression on the text data before encapsulating it into the VPN tunnel, and performs weak encryption on the non-text data before encapsulating it into the VPN Tunneling, this process is completed at the middleware layer. Non-text data includes image data, audio data, and video data; such as figure 2 As shown, the traffic classifier includes a traffic classifier based on application labels in classification strategy 1 and a traffic classifier based on user behavior in classification strategy 2;

[0016] Classification strategy 1, traffic classifier design based on application la...

Abstract

The invention discloses a VPN protocol suitable for mobile devices. The VPN client classifies the traffic of an intelligent terminal through a traffic classifier, divides it into text data and non-text data, and performs strong encryption and compression on the text data before packaging it into For VPN tunnels, non-text data is weakly encrypted and then encapsulated into VPN tunnels. This process is completed at the middleware layer. The invention has the beneficial effects of ensuring the service quality of VPN service and the performance of VPN client while ensuring reliable encrypted transmission service.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a VPN protocol suitable for mobile equipment. Background technique [0002] Virtual Private Network (VPN) technology provides security assurance for Internet access, and is widely used in traditional hardware devices such as servers, routers, switches, and PCs in the form of software services. VPNs deployed on servers, routers, and switches usually provide firewalls and secure remote access services for LAN user groups in the form of security gateways. VPNs built on PCs usually provide individual users with private and secure encrypted tunnels to ensure users' online privacy. [0003] Faced with the contradiction between the rapid development of smart mobile devices such as smart phones and tablet computers and the increasingly severe situation of mobile device network security, VPN technology is gradually being applied to mobile device terminals. As far as the current rese...
