Abstract:
1. A method for implementing device grouping and interactions between grouped devices, wherein in a network, a device creating a device group sends an advertisement message carrying identification information of a device group to which it belongs, to the network; and after receiving the advertisement message, a network device which wants requests to join in the corresponding device group joins in the device group identified by the corresponding advertisement message, when two grouped network devices interact with each other, the method further comprising: sending by an initiating device, an access request to an accessed device; judging by the device receiving the access request, whether the device sending the request is a trusted device thereof or not, 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, wherein said accessed device belongs to a master-slave device group, and determining by the initiating device and the accessed device, a common trusted third party comprises: judging by the initiating device, whether the initiating device belongs to one and the same master-slave device group as the accessed device, if so, using a master device as the common trusted third party; otherwise, joining by the initiating device, as a slave device, in a master-slave device group to which the accessed device belongs, and then using a master device of the master-slave device group in which the initiating device joins as the common trusted third party.
