Method for managing profile of Embedded UICC, and Embedded UICC, Embedded UICC-equipped terminal, provision method, and method for changing MNO using same
Abstract:
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.
Abstract(Chinese):

本发明提供一种方法，其中，在SM被划分并实现为SM-SR和SM-DP（数据准备）的环境中，MNO通过SM-SR（安全路由）接收分配给相应的嵌入式UICC（eUICC）的秘密密钥 ），也就是说，提供了一种方法，其中MNO通过SM-SR从对应的eUICC动态地获取秘密密钥（公开密钥等），并使用获取的秘密密钥。 此外，本发明允许eUICC从MNO或SM接收加密的简档，并使用存储在eUICC中的配置文件访问凭证信息（对应于eUICC公开密钥的秘密密钥）解密加密的简档，以使用解密的配置文件 从而安全地发送诸如操作简档等重要数据，并阻止外部实体（如设备或终端）访问重要数据。
