Method and device for southing security authentication in software-defined networking

Abstract

The embodiment of the invention provides a method and a device for southing security authentication in software-defined networking. The method is applied to a controller and comprises the steps of receiving an access request of a switch, wherein the access request comprises identification information of the switch and first verification data, and the first verification data is data required after the identification information of the switch is encrypted through a preset encryption mode; encrypting the received identification information according to the preset encryption mode so as to acquire second verification data; judging whether the second verification data is identical to the first verification data or not; and sending feedback information indicating agreement for access to the switch if the second verification data is identical to the first verification data so as to enable the switch to access to the software-defined networking. In conclusion, the authentication method provided by the embodiment of the invention not only effectively ensures the southing security of the software-defined networking, but also is simple, practicable, convenient to implement and high in authentication efficiency.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a southbound security authentication method and device in a software-defined network. Background technique [0002] With the continuous development of computer technology, software-defined network SDN (Software-Defined Networking) has attracted more and more attention from the industry and research fields. As a new network architecture, SDN separates the control function from each switch and concentrates it on the controller, which facilitates the flexible configuration of switches through programming and improves the efficiency of network management. In order to ensure the southbound security of the entire SDN and prevent some users from maliciously using an external switch to impersonate a local switch to access the controller, when the switch is connected to the controller, the controller will perform southbound security authentication on the switch, and only if the authenti...

Problems solved by technology

It can be seen that in this authentication method, the authentication of both the controller and the switch is also required, and the third authentication file needs to be manually copied to the controller, so the implementation of this authentication method is also very troublesome and time-consuming.
