CT WG6 - Smart Card Application Aspects

Within the 3GPP Technical Specification Group Core Network and Terminals, the main objectives of the 3GPP TSG CT WG6 (CT6) are:

The development and maintenance of specifications and associated test specifications for the 3GPP secure access applications, which are based on secure platforms (e.g. UICC) developed by ETSI TC SET and the interface between these applications with the Mobile Terminal.

Including:

- Subscriber Identity Module (SIM), which is used by 2G systems;
- Universal Subscriber Identity Module (USIM) application, which is used by 3GPP systems;
- IP Multimedia Services Identity Module (ISIM) application with the exception of the security algorithms (developed by SA WG3);
- Hosting Party Subscription Identity Module (HPSIM) application.
- Slice subscriber identity module (SSIM)

CT WG6 is currently responsible for the design and specifications of the evolution of the USIM application, for instance:

- For securely accessing 3GPP Mobile networks over 3GPP and Non-3GPP accesses
- Providing user privacy by concealing the users identity in 3GPP Mobile networks
- To support configuration capabilities for 3GPP Mobile services, e.g. steering of roaming, V2X, wireless wireline convergence, multi device multi identity
- Specification of 3GPP Mobile related conformance tests for the interface between UICC applications and mobile devices
- Specification of a solution to provide secure authentication of Ambient IoT devices based on SA3 requirements
- Specification of APIs to be used by USAT applications
