Abstract

The invention provides a switching method of a communication protocol and a switching device of the communication protocol, wherein the method comprises the following steps: a VPN (virtual private network) gateway device receives a data packet from a sending party during the negotiation process of a main mode; the VPN gateway device obtains the characteristics information of the data packet from the data packet; the VPN gateway device determines a first communication protocol adopted by the sending party according to the characteristics information; the VPN gateway device switches a second communication protocol supported at present into the first communication protocol. By adopting the technical scheme provided by the invention, the switching method and device of the communication protocol solves the problem that products supporting a standard protocol in the market and products supporting protocol stipulated in IPSec VPN Technical Code cannot realize the interworking in the related technology; by judging if the opposite side uses the standard protocol or the protocol stipulated in the IPSec VPN Technical Code, the negotiation protocol supported by the opposite side can be automatically switched according to the protocol used by the opposite side.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication protocol switching method and device. Background technique [0002] The market for virtual private network (Virtual Private Network, referred to as VPN) related technologies and products applying VPN technology is very mature. At present, the most used VPN products are mainly based on IP security protocol (Internet Protocol Security, referred to as IPSec) VPN. (Such as figure 1 shown), a data encryption key is generated after key negotiation through the Internet Key Exchange (IKE) protocol, and the transmitted data is encapsulated and encrypted with this key. [0003] Of course, it should be noted that the standard VPN technology and its products have certain defects, and the vulnerabilities caused by these defects are often exploited by hackers. For example, in the current IPSec VPN products, there are main mode and aggressive mode. Two authentication methods,...
