Embodiment Construction

[0022] In the following description, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. For purposes of explanation and not limitation, specific details are set forth, such as specific examples and techniques, to provide a thorough understanding.

[0023] figure 1 A logical architecture of a universal integrated circuit card (UICC) 100 as an example of a trusted execution environment according to an embodiment of the present invention is schematically presented. Furthermore, the association between the Security Domain (SD) and the Subscription Manager role is indicated.

[0024] The UICC 100 includes a profile selector application 102 that can receive information about applications for enabling profile domains. The UICC also includes two management domains of the Profile domain. These administrative domains are Profile Domain Administrative Domain 1,104 and Profile Domain Administrative Domain 2,106. Profile D...

Abstract

A Trusted Execution Environment (TEE) enabling one of at least two profile domains is disclosed. An authorization token is received (816, 1102) for authorizing the TEE application to request the TEE application to enable one of the at least two profile domains. Checking (818, 1104) the validity of the authorization token. If the authorization token is valid, storing (820, 1106) information about TEE applications authorized to request enabling of one of the at least two profile domains. If a command is received (822) requesting an authorized TEE application to request (824, 1108) enable one of the at least two profile fields, then enable (826, 1110) one of the at least two profile fields. The TEE comprises a processor and a memory for storing a computer program comprising computer program code for performing the method when the code is run in the processor.

Description

technical field [0001] The present disclosure relates to profile change management for trusted execution environments. More particularly, it relates to methods and trusted execution environments for enabling (ie, causing a profile domain to be enabled) a profile domain. Background technique [0002] The present invention relates to Trusted Execution Environments (TEEs) and Universal Integrated Circuit Cards (UICCs). ETSI Technical Specification (TS) 103383 provides the requirements for an embedded UICC (eUICC). The purpose of this standard is to allow remote provisioning and management of operator "profiles", which is a technical term defining programs and data for subscriptions on a UICC with some Subscriber Identity Module (SIM) application. This is to enable the eUICC to be soldered to the device and never removed. [0003] Use cases for UICC include "late binding" and "operator change" in machine-to-machine services. The former refers to the ability to define a Mobil...
