Abstract: Provided are a method and electronic device for storing a digital key. The electronic device includes: a communicator; a secure element configured to store a digital key and perform authentication related to the digital key; a memory storing a program and data for storing the digital key; and a processor configured to execute the program stored in the memory to perform authentication on a target device and a user of the electronic device by performing short range communication with the target device, generate the digital key for the target device, and store the generated digital key in one region of the secure element.

Abstract: A method for transmitting and receiving data between a first cluster and a second cluster by a first device of the first cluster, the first device, and a second device are provided. The method includes notifying a second device of the second cluster of a presence of the first device through a discovery beacon, transmitting information about a service that the first device provides to the second device, receiving a data path setup request from the second device that updates a channel active period to be equal to a channel active period of the first device based on the discovery beacon, and transmitting a data path setup response to the second device in response to the data path setup request, wherein a data path is established between the first device and the second device and is used to transmit or receive data to/from the second device.
