摘要

PURPOSE: A profile backup method in an eUICC, the eUICC, an external entity, a backup device, and a system thereof are provided to store a profile in the eUICC.;CONSTITUTION: An encryption module(1220) encrypts a profile in an eUICC managed by connecting an external entity. A communication module(1230) transmits the profile encrypted by the encryption module to a backup profile for storing the profile in a backup device. The encryption module dually encrypts the profile in the eUICC. The encryption module encrypts the profile in the eUICC according to the reception of a backup command from the backup device.;COPYRIGHT KIPO 2013;[Reference numerals] (1210) Backup trigger module; (1220) Encryption module; (1230) Communication module; (AA,BB) Profile
