Abstract

The invention provides an SSL VPN (secure sockets layer virtual private network) terminal data interaction method based on an NDIS (network driver interface standard). An SSL VPN gateway is connected with an NDIS center driver through a virtual network interface card. The NDIS center driver is communicated with a network application procedure through a TCP / IP (transmission control protocol / internet protocol) protocol stack. An SSL VPN client side is introduced between the SSL VPN gateway and the virtual network interface card, and is used as a middle transmission medium of the SSL VPN gateway and the virtual network interface card, and therefore both direction transmission of data is achieved. The SSL VPN terminal data interaction method based on the NDIS effectively reduces time delay generated by network data transmission, and guarantees that corresponding modules are timely informed of data processing after the data is received.

Description

technical field [0001] The invention relates to an NDIS-based SSL VPN terminal data interaction method, in particular to an NDIS-based SSL VPN terminal data interaction method applicable in the technical field of communication. Background technique [0002] SSL is the abbreviation of Secure Socket Layer (Secure Socket Layer Protocol), which can provide confidential transmission on the Internet. SSL uses public key technology. Its goal is to ensure the confidentiality and reliability of the communication between two applications, and it can be supported on both the server side and the user side. At present, the SSL protocol using public key technology has become the industry standard for secure communication on the Internet. [0003] VPN (Virtual Private Network, Virtual Private Network) is defined as establishing a temporary and secure connection through a public network (usually the Internet), and is a safe and stable tunnel passing through the public network. VPN can he...
