Embodiment Construction

[0021] In order to solve the problem that the prior art prevents branch subnets from actively negotiating and resulting in enhanced limitations of branch subnets, the present invention provides a multi-subnet networking method, device, storage medium and computer equipment, which are combined with the accompanying drawings below And embodiment, the present invention is described in further detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] The first embodiment of the present invention provides a multi-subnet networking method, which can be applied to any one of the central terminal or the branch terminal, and its flow chart is as follows image 3 As shown, it mainly includes steps S101 to S104:

[0023] S101, obtain the first subnet pair in the subnet pair to be configured, establish a communication tunnel between the two subnets of the first subnet pair, and...

Abstract

The invention discloses a networking method, a device, a storage medium and a computer device of a plurality of subnets. The method comprises the following steps: a communication tunnel is establishedbetween two subnets of a first subnet pair, and a communication key between two subnets of the first subnet pair is configured; the communication key between two subnets of the first subnet pair is set up. Obtaining configuration data and storing the configuration data as a first connection table, wherein the first connection table comprises at least IP of two subnets of the first subnet pair; replacing the IP of the two subnets of the first subnet pair in the first connection table with the IP of the two subnets of the second subnet pair to obtain a multiplexing connection table of the second subnet pair; according to the multiplexed connection table of the second subnet pair, a communication key between two subnets of the second subnet pair is configured. By establishing a connection table and directly multiplexing the contents other than the subnet in the connection table, the invention separates the tunnel establishment in one stage from the key configuration process in two stages, and on the basis of quickly establishing the subnet, the invention enables both ends to initiate negotiation.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a multi-subnet networking method, device, storage medium and computer equipment. Background technique [0002] Internet Protocol Security (IPSec, InternetProtocolSecurity) is an open standard framework structure, through the use of encrypted security services to ensure confidential and secure communication on the Internet Protocol (IP) network. The IPSec tunnel negotiation is divided into two phases: the first phase of negotiation is to authenticate the identity of the other party, and a safe and reliable tunnel (IPSec tunnel) is provided for the second phase of negotiation. The second stage mainly generates the secret key that can actually be used to encrypt the data stream. After the tunnel configured by the user completes the first phase and the second phase of negotiation, the data on the protected subnet flow will be encrypted to ensure the integrity and reliabilit...
