According to an embodiment, a method, performed by an electronic device, of providing a ranging-based service may include: transmitting, from a service application installed in the electronic device to a framework, information related to service data, the information related to the service data including a service deployment case and information about a storage location of the service data; when the electronic device approaches a reader device, receiving first data from the reader device; setting up a secure channel with the reader device by using information stored in a common applet identified based on the first data, the common applet being installed in a secure component of the electronic device; and transmitting the service data to the reader device, based on second data received from the reader device.

Electronic device and method for providing service data based on service deployment case in wireless communication system

Provided is a method of accessing a service by using authentication of an electronic device. An operation method of the electronic device includes: selecting a cloud server for storing data, based on first authentication information including an identifier of the electronic device and network addresses of a plurality of cloud servers; transmitting, to a service providing server, second authentication information including the identifier of the electronic device, a network address of the selected cloud server, and information about a service executed on the electronic device; and receiving, from the service providing server, information about a result of subscribing to the service determined based on the second authentication information.

Device and method for accessing service using authentication of electronic device

Provided is a method, performed by an electronic device, of managing keys for accessing a plurality of services. The method includes transmitting, by a secure domain (SD) in a secure area of the electronic device, a certificate of the SD to a plurality of service providers (SPs); receiving, by an application installed in the electronic device, a certificate of each of the plurality of SPs from the plurality of SPs; receiving, by the application, first signed data from a first SP among the plurality of SPs; authenticating, by the application, the first signed data by using a certificate of the first SP received from the first SP and obtaining an encrypted key of the first SP from the first signed data; decrypting, by the SD, the encrypted key of the first SP by using a private key of the SD; and storing the decrypted key of the first SP in a first instance corresponding to the first SP among a plurality of instances of the SD.

Method and electronic device for managing digital keys

Provided are an entrance management system and an operating method thereof. The operating method of an entrance management system may include: detecting an electronic device by using short-range wireless communication; measuring a distance from the electronic device; when the electronic device enters a set first range, opening an entrance; and when the distance from the electronic device decreases to a preset value or less, closing the entrance.

Entrance management system and operation method thereof

The present disclosure relates to a method and device for performing access control by authenticating an electronic device and performing secure ranging. The method may include: receiving, from a server, a device certificate including a first scrambled timestamp sequence (STS) code encrypted by a public key of the electronic device and a second STS code encrypted by an STS key; transmitting the device certificate to a target device; obtaining the first STS code by decrypting the encrypted first STS code by using a secret key of the electronic device; and performing secure ranging with the target device by using the first STS code.

Method and device for performing access control by using authentication certificate based on authority information

The disclosure relates to a method and apparatus for authenticating an electronic device. An operating method of a target device according to an embodiment includes generating a random value based on whether an electronic device is within a certain distance from the target device, transmitting, to the electronic device, first information including the generated random value and identification information of the target device, and receiving, from the electronic device, first authentication information obtained based on the first information, encrypting the received first authentication information and a target device key, transmitting the encrypted target device key and the encrypted first authentication information to a server, and receiving, from the server, second authentication information obtained based on the first authentication information, and determining whether to open or close a door based on a comparison between the second authentication information and the random value.

Electronic device authentication method, and apparatus according thereto

Provided is a method, performed by an electronic device, of managing keys for accessing a plurality of services in an integrated manner to improve interoperability and secure security. The method includes transmitting, by a secure domain (SD) in a secure area of the electronic device, a certificate of the SD to a plurality of service providers (SPs); receiving, by an application installed in the electronic device, a certificate of each of the plurality of SPs from the plurality of SPs; receiving, by the application, first signed data from a first SP among the plurality of SPs; authenticating, by the application, the first signed data by using a certificate of the first SP received from the first SP and obtaining an encrypted key of the first SP from the first signed data; decrypting, by the SD, the encrypted key of the first SP by using a private key of the SD; and storing the decrypted key of the first SP in a first instance corresponding to the first SP among a plurality of instances of the SD.
