Abstract

The embodiment of the invention discloses a method and device for encapsulating a message and a method and device for decapsulating the message. The method for encapsulating the message comprises the steps that message header information of the preset length is generated; data of the preset length at the beginning of the original message are spiced to the ending position of the original message; the generated message header information is used for covering the data of the preset length at the beginning of the original message. According to the method and device for encapsulating the message and the method and device for decapsulating the message, data copying in the message encapsulating and decapsulating process is reduced, and message encapsulating and decapsulating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a message encapsulation method and device, and a message decapsulation method and device. Background technique [0002] A virtual private network (Virtual private network, VPN) refers to a logical virtual subnet formed by connecting physically distributed networks in different locations through a public network. It uses authentication, access control, confidentiality, and data integrity security mechanisms to build a private network on the public network, so that data can be transmitted in the public network through a secure "encrypted pipeline". [0003] Packet encapsulation is a key technology in virtual private network. By encapsulating the packets to be transmitted, a virtual pipeline can be established between nodes on the public network, thereby building a private network on the public network. [0004] Existing packet encapsulation technologies mainly include L...
