Safe access method, device and equipment for Internet of Things equipment and medium

The invention relates to the field of Internet of Things, and provides an Internet of Things equipment security access method and device, equipment and a medium, a target strategy of target equipment is acquired from a security strategy list, and to-be-accessed equipment with different security levels executes different security strategies, so that the method is more targeted, excessive consumption of resources can be avoided, and the access efficiency is improved. The target information is extracted from the device information of the target device according to the target strategy, the to-be-authenticated data is generated according to the target information, different devices can generate different to-be-authenticated data, subsequent targeted authentication is facilitated, and the target strategy and the to-be-authenticated data are sent to the cloud platform and the target device for security authentication. The security authentication result of the cloud platform on the target equipment is received, and w
