METHOD FOR CHANGING MNO IN EMBEDDED SIM ON BASIS OF DYNAMIC KEY GENERATION AND EMBEDDED SIM AND RECORDING MEDIUM THEREFOR |
摘要 |
The present invention Includes using an embedded SIM (eSIM) associated with a newly-opened mobile network operator (MNO) system and a receiving MNO system, the method performs the steps of: generating a security domain (SD) for a receiving MNO on the basis of a request from the newly-opened MNO system; injecting a prior SD key value; installing a secure applet for key generation and secure arithmetic operations, injecting a new SD key value on the basis of a request from the receiving MNO, and transmitting only a public key to the receiving MNO system after generating key pairs for the receiving MNO; and decoding a receiving MNO profile with a private key corresponding to the public key after receiving the receiving MNO profile from the receiving MNO system or the newly-opened MNO system. |
