US 10,476,671 B2 · Method and device for installing profile of eUICC

Abstract

The present disclosure relates to a method and a device for installing a profile of an embedded universal integrated circuit boards (eUICC) and, more particularly, to a method and a device for remotely installing mobile communication subscriber information (profile) substituting for a universal integrated circuit boards (UICC), on a security module. In an aspect, a network device, acquires at least one of or more profiles encrypted with a first password key and one or more first password keys encrypted with a second password key; and when profile installation for the eUICC starts, transmits to, at least one eUICC, the one or more encrypted profiles and the one or more encrypted first password keys, wherein, prior to the transmission, each first password key is re-encrypted with a third password key for installation by the corresponding one or more eUICCs.

Dependent claims

A method by a network device for installing a profile of an embedded universal integrated circuit card (eUICC) of a terminal, the method comprising:

acquiring, from a profile generating server, a profile encrypted with a first security key and the first security key encrypted with a second security key, wherein the second security key is for mutual authentication between the profile generating server and the network device;
acquiring the first security key encrypted with a third security key corresponding to the eUICC;
and
transmitting the encrypted profile and the first security key encrypted with the third security key to the terminal having the eUICC,
wherein, during a profile installation, the profile encrypted with the first security key is decrypted with the first security key and is installed in the eUICC.

2 more elements

A network device for installing a profile of an embedded universal integrated circuit card (eUICC) of a terminal, the network device comprising:

a transceiver;
and
at least one processor coupled with the transceiver and configured to control to:
acquire, from a profile generating server, a profile encrypted with a first security key and the first security key encrypted with a second security key, wherein the second security key is for mutual authentication between the profile generating server and the network device,
acquire the first security key encrypted with a third security key corresponding to the eUICC, and
control the transceiver to transmit the encrypted profile and the first security key encrypted with the third security key to the terminal having the eUICC,
wherein, during a profile installation, the profile encrypted with the first security key is decrypted with the first security key and is installed in the eUICC.
