Method And Apparatus For Access Control In Distributed Blockchain-based Internet Of Things (iot) Network
An electronic device is provided. The electronic device includes a memory, a communication circuitry, and a processor configured to transmit, a first signal for requesting to access an external device, to the external device, receive, a second signal for requesting to provide a token stored in the electronic device, from the external device, the token being generated based on at least part of a block chain including at least one block that is respectively associated with at least one external device that has been accessed by the electronic device, in response to the reception, transmit, information on the token, to the external device, receive, a third signal indicating allowed the access, from the external device, the third signal being transmitted from the external device in response to identifying, by the external device, to validate the token in all of the plurality of external devices, and access the external device based on the third signal.

- 1. An electronic device in a system including a plurality of external devices, the electronic device comprising:
a memory configured to store instructions; a communication circuitry; and a processor operably coupled to the communication circuitry, the processor configured to execute the stored instructions to:
transmit, by using the communication circuitry, a first signal for requesting to access an external device among the plurality of external devices, to the external device,
receive, by using the communication circuitry, a second signal for requesting to provide a token stored in the electronic device, from the external device, the token being generated based on at least part of a block chain including at least one block that is respectively associated with at least one external device that has been accessed by the electronic device among the plurality of external devices,
in response to the reception, transmit, by using the communication circuitry, information on the token, to the external device,
receive, by using the communication circuitry, a third signal for indicating to allow the access of the electronic device, from the external device, the third signal being transmitted from the external device in response to identifying, by the external device, to validate the token in all of the plurality of external devices, and
access, by using the communication circuitry, the external device based on at least part of the third signal for indicating to allow the access of the electronic device.
- 9. An electronic device in a system including a plurality of external devices, the electronic device comprising:
a memory configured to store instructions; a display; a communication circuitry; and a processor operably coupled to the communication circuitry, the processor configured to execute the stored instructions to:
display a first user interface including at least one object corresponding to at least one external device accessible by the electronic device among the plurality of external devices,
in response to detecting an input on an object among the at least one object, transmit, to the external device, a first signal for requesting to access an external device corresponding to the object,
receive, from the external device, a second signal for requesting to provide a token generated based on at least part of a block chain,
in response to the reception, transmit, to the external device, information on the token,
receive, from the external device, a third signal for indicating to allow the access of the electronic device, the third signal being transmitted from the external device in response to identifying, by the external device, to validate the token in all of the plurality of external devices, and
in response to receiving the third signal, display, in the first user interface, a message for indicating to allow the access of the electronic device.
- 17. A non-transitory computer readable storage medium having a computer readable program stored therein, the computer readable program, when executed on at least one processor in a server, configures the at least one processor to:
receive, from an external device among a plurality of external devices included in a system associated with the server, information on a token that is provided from an electronic device to the external device; transmit, to remaining external devices among the plurality of external devices, the information on the token; receive, from the plurality of external devices, information on results validating the token in the plurality of external devices respectively; and transmit, to the external device, a signal for indicating to allow an access of the electronic device to the external device.
