Abstract

The invention provides an integrity authentication method and device for virtual client equipment. The method comprises the following steps: an SD-WAN controller sends an integrity challenge signaling to the virtual client equipment; receiving a first integrity measurement list sent by the virtual client device, wherein the first integrity measurement list is generated by the virtual client device by using the integrity measurement system structure and signed by using the virtual trusted computing chip; performing integrity authentication on the virtual client device according to the first integrity measurement list; if the integrity authentication of the virtual client device is passed, indication information is sent to the virtual client device, and the indication information is used for indicating the credibility of a physical client device where the virtual client device is located. In the invention, the SD-WAN controller performs integrity authentication on the virtual client device, so that the virtual operating system of the virtual client device can be ensured not to be tampered, the predictability of the behavior of the virtual operating system is ensured, and the security of the system is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of information security, and in particular, to an integrity authentication method and device for a virtual client device. Background technique [0002] SD-WAN (Software Defined WAN, Software Defined Wide Area Network) is a service formed by applying SDN (Software Defined Network, Software Defined Network) technology to WAN scenarios. This service is used to connect enterprise networks, data centers, Internet applications and cloud services across a wide geographic area, and is designed to help users reduce WAN expenses (low cost) and increase network connection flexibility. Through the software-defined method, it provides intelligent route selection, convenient deployment, and simple maintenance of WAN. [0003] Customer Premise Equipment (CPE) is the key device of SD-WAN. The device is deployed on the user side to provide users with software-defined virtual WAN services. In the curre...
