Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for downloading profiles in a terminal in a wireless communication system include generating and storing an encryption key at a time point, loading the stored encryption key, when receiving profile download start information from a profile providing server, and downloading an encrypted profile for the electronic device from the profile providing server, via the loaded encryption key, and installing the encrypted profile in the electronic device. An electronic device configured to download a profile in a wireless communication system includes a memory, and a controller configured to generate an encryption key at a time point, store the encryption key in the memory, loading the stored encryption key, when receiving profile download start information from a profile providing server, and downloading an encrypted profile for the electronic device from the profile providing server, by using the loaded encryption key, and installing the downloaded profile.

Claims

1. A method of downloading a profile by an electronic device in a wireless communication system, the method comprising:

storing a generated encryption key;

receiving, after the storing, information indicating a start of a profile download; and

downloading, from a profile providing server, a profile for a universal integrated circuit card (UICC) of the electronic device by using the encryption key, based on the received information.
