Abstract
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.
