Abstract

The invention discloses an implementation method of a network VPN cipher machine based on no IP address, and relates to the technical field of network management. According to the invention, the communication between the network VPN cipher machines does not need to depend on the own IP address to carry out encryption packaging processing, and does not depend on the IP address to carry out management configuration, thereby achieving the purposes of saving the IP address resource of the Internet and guaranteeing the transmission secrecy of the network message and the anti-permeation protection of the network.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a method for realizing a network VPN cipher machine based on no IP address. Background technique [0002] The traditional VPN cipher machine has its own IP address, and the IP address of the VPN cipher machine needs to be configured before use. The VPN cipher machine adopts the tunnel mode to realize the encryption, decryption and encapsulation of data packets. Generally, a negotiation protocol is adopted between VPN cipher machines to negotiate encryption algorithms, encryption keys, and encryption policies, so as to realize the encryption and decryption of data packets between cipher machines and achieve the purpose of network communication security. In this mode, the VPN cipher machine must occupy an IP address of the external network, and the IP address must be set during deployment. Especially when adding a new VPN cipher machine, the encryption policy between the...
