Certification method using an embedded UICC certificate, provisioning and MNO changing methods using the certification method, embedded UICC therefor, MNO system, and recording medium

摘要

The present invention relates to a system constituted by a mobile network operator (MNO), a subscription manager (SM), and an embedded UICC (eUICC), wherein the MNO system or the SM stores an eUICC certificate that can verify the identity of the eUICC, transfers the eUICC certificate to the MNO system or the SM in a provisioning or MNO changing process, verifies the identity of a corresponding eUICC using the received eUICC certificate, and encrypts and transfers a profile to the eUICC only if the verification is successful so that the eUICC may be verified during the provisioning or MNO changing processes.

1. A method of certifying an embedded universal integrated circuit card (eUICC) cooperating with a mobile network operator (MNO) system and a subscription manager (SM), the method comprising:
storing, by the eUICC, an eUICC certificate used for the MNO system or the SM to verify an identity of the eUICC; and transmitting, by the eUICC, the eUICC certificate to the MNO system or the SM, wherein the SM comprises a subscription manager-secure routing (SM-SR) and a subscription manager-data preparation (SM-DP), both of which perform an encryption function such that the eUICC certificate is double encrypted upon a condition that both the SM-SR and SM-DP are instructed to perform said encryption.
