Abstract

The present invention relates to the field of encrypted data transmission, in particular to an IPSec VPN encryption method and device for supporting a mobile terminal. The prior art of the present invention has a problem and provides an encryption method and device. The method and device support tunnel negotiation when an IP address of the mobile terminal is not visual, support verifying the mobile terminal through a certificate or a device identity, and support a tunnel to automatically adapt a new IP address when the IP address of the terminal dynamically changes after the tunnel is established so as to adapt mobile office environment requirements and meet access requirements of the mobile terminal. The method of the present invention comprises: sending an IKE key negotiation request by the mobile terminal with a built-in gateway; after an encryption gateway receiving the negotiation request from the mobile terminal, performing data key negotiation, performing judgement on the plaintext of a negotiation package, and adding the IP of the mobile terminal into an SA data structure; generating an IP message encryption key and a corresponding sequence number (SPI) after the negotiation is completed; and establishing an encryption tunnel between the mobile terminal and the encryption gateway and then performing data transmission.

Description

technical field [0001] The invention relates to the field of encrypted data transmission, in particular to a method and device for supporting mobile terminals to transmit IPSecVPN messages. Background technique [0002] IPSeC (IPSeCurtyProtcol, IP Security Protocol) is a set of open standards that work together to ensure data confidentiality, data integrity, and data authentication between peer devices. A major advantage of IPSec VPN over other remote access solutions is that it uses centralized security and policy management components, which greatly eases maintenance requirements. Therefore, it has been widely used in helping remote users, company branches, business partners and suppliers to establish credible and secure connection solutions within the company's intranet. [0003] 1. Existing solutions of IPSecVPN [0004] IPSecVPN is a secure data transmission protocol between encrypted gateways and encrypted gateways. The network topology, negotiation process, message ...
