METHOD FOR MANAGING PROFILE OF EMBEDDED UICC, AND EMBEDDED UICC, EMBEDDED UICC-EQUIPPED TERMINAL, PROVISION METHOD, AND METHOD FOR CHANGING MNO USING SAME |
摘要 |
The present invention provides a method wherein an MNO receives a secret key allocated to a corresponding embedded UICC (eUICC) through SM-SR (secure routing) in an environment where SM is divided and implemented as SM-SR and SM-DP (data preparation), that is, provided is a method wherein the MNO dynamically acquires the secret key (public key or the like) from the corresponding eUICC through the SM-SR and uses the acquired secret key. In addition, the present invention allows the eUICC to receive an encrypted profile from the MNO or the SM and decrypts the encrypted profile using profile access credential information (a secret key corresponding to an eUICC public key) stored in the eUICC to use the decrypted profile, thereby securely transmitting important data such as operation profiles, and blocking external entities such as a device or terminal from accessing the important data. |
