Abstract
In a method for implementing device grouping and interactions between grouped devices a device creating a device group sends an advertisement message carrying identification information of a device group to which it belongs, to the network. After receiving the advertisement message, a network device joins the device group by the corresponding advertisement message. When two grouped network devices interact with each other, the method further comprises: sending an access request to an accessed device; judging by the accessed device whether the device sending the request is a trusted device and if so, interacting by both parties with each other; otherwise, denying the access request, or determining by the initiating device and the accessed device, a common trusted third party; acquiring by the initiating device, key information of the accessed device from the common trusted third party, and interacting with the accessed device by using the acquired key information.
