Abstract

The invention provides a message processing method and virtual private network SSLVPN server, and is used for solving the technical problem of low message processing efficiency of an existing SSLVPN server. The method is applied to a virtual private network SSLVPN server, the SSLVPN server includes a data flow processor which works in a kernel state, and the method includes the following steps: the SSLVPN server receives a connection control message sent by a client, wherein the connection control message is used for performing key negotiation of a Secure Sockets Layer (SSL) with the client; the SSLVPN server sends the connection control message from the kernel state of the SSLVPN server to a user state process, and the user state process is used for processing the connection control message to obtain a negotiation result; and the SSLVPN server receives a data message and utilizes the data flow processor to process the data message according to the negotiation result.

Description

technical field [0001] The invention relates to the field of computers, in particular to a message processing method and a virtual private network SSLVPN server. Background technique [0002] VPN (Virtual Private Network, Virtual Private Network) is essentially a new encapsulation of data packets transmitted on the public network in the form of open plaintext according to a certain protocol and encryption scheme. On the one hand, private data transmission across the public network is realized. On the other hand, it makes the remote user feel as if it is directly connected to the internal network, which increases the transparency of the user's use of the internal network. [0003] SSLVPN (Secure Sockets Layer VPN, Secure Sockets Layer VPN), as a kind of VPN, is established on the basis of the SSL protocol. With the development of technology, a technical solution for transplanting SSLVPN to a high-performance heterogeneous forwarding platform appears in the prior art. [000...
