Embodiment Construction

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0023] figure 1 For a flowchart of a method for establishing an IP security tunnel provided by an embodiment of the present invention, please refer to figure 1 , the method includes:

[0024] Step 101: Determine at least one link of the traffic to be encrypted and the devices on the at least one link according to the tracking TRACE information of the traffic to be encrypted;

[0025] Among them, the TRACE information is the tracking information. Since the information is transmitted from one end to the other end through many transmission media and...

Abstract

The embodiment of the invention provides an internet protocol (IP) security tunnel establishing method and an IP security tunnel establishing device. The method comprises the following steps of: according to TRACE information required to encrypt flux, determining at least one link required to encrypt flux and equipment along the link; for each link indicated in the TRACE information, trying to establish IP security tunnels with the equipment along the link in a hop-by-hop way from the remote one to the near one; and when the trying of establishing one security tunnel with one piece of equipment on each link is successful, stopping trying, and determining that the establishment of the IP security tunnels required to encrypt flux on the link is finished. By the method and the device of the embodiment of the invention, the longest IP security tunnel can be automatically generated, and more network protection is provided.

Description

technical field [0001] The invention relates to the network field, in particular to a method and device for establishing an IP security tunnel. Background technique [0002] The Internet (Internet), also known as the Internet, is a global network connected by computers that communicate with each other using a common language. It is a truly global network. With the rapid expansion of the Internet, people rely more and more on it. Therefore, encryption technology is urgently needed to ensure the security of communication. [0003] For example, for a company intending to engage in e-commerce, communication security is a basic prerequisite. For sensitive information such as credit card numbers, they must be effectively protected, and merchants must be able to Authenticate and authorize. For another example, businesses can connect offices or subsidiaries scattered in various places through the Internet, and e-mails (or even telephone calls) can be routed between offices through...
