Abstract
An eUICCembedded in an UEauthenticates an AUTN transmitted from an HSS, and calculates a transfer key TK by using a secret key K. The eUICCacquires a transfer Token by decoding an enc Token by using the transfer key TK, and acquires a new Customer ID by decoding an enc New ID by using the transfer key TK. The eUICCtransmits a user auth resp in response to a User auth+transfer Setup Req including the AUTN, the enc Token, and the enc New ID to the HSS. The eUICCgenerates a shared-Secret Key shared between the eUICCand an HSSby using the transfer Token, and executes an attach procedure for the HSSby using the generated shared-Secret Key and the new Customer ID.
