Abstract: Proposed are a method and a device for transmitting and receiving important update information of another AP through an ML element in a WLAN system. Specifically, a receiving MLD receives a basic ML element from a transmitting MLD over a first link. The receiving MLD decodes the basic ML element. The basic ML element includes a profile field of the second transmitting STA. The profile field of the second transmitting STA includes a first CSF presence field. When the value of the first CSF presence field is set to 0, the profile field of the second transmitting STA includes a first CSF field. The first CSF field includes information about the current change sequence number of the second transmitting STA.

Abstract: An Internet of Things (IoT) device may transmit, to a Blockchain Node, a registration request signal including a public key certificate of the IoT device and a universally unique identifier (UUID) of the IoT device. The IoT device may receive, from the Blockchain Node, a first certification identifier (ID) for the IoT device, wherein the first Certification ID is a newly generated block. The IoT device may receive a first encrypted signal from an onboarding tool (OBT), wherein the encrypted signal includes a second certification ID of the OBT and encrypted information being encrypted based on a private key of the OBT. And, the IoT device may transmit, to the Blockchain Node, a verification request signal including the second certification ID of the OBT.
