Tamper resistant device for an integrated circuit card

An electronic device comprising:

• a tamper resistant device implementing an integrated circuit card, the tamper resistant device storing a first security domain that includes a telecommunication profile and a second security domain that includes an application profile;
• a baseband processor configured to operate with a mobile telecommunications network;
• an application processor;
• a first physical interface configured to allow access from the baseband processor to the telecommunication profile, the first physical interface being a serial peripheral interface (SPI);
• and
• a second physical interface configured to allow access from the application processor to the application profile, the second physical interface being an International Standards Organization (ISO) interface, wherein the tamper resistant device is configured to enable accessibility to the application profile if corresponding commands are received in signals exchanged on the first interface and to enable accessibility to the telecommunication profile if corresponding commands are received in signals exchanged on the second interface.

A method of accessing profiles in a tamper resistant device implementing an embedded Universal Integrated Circuit Card, the device comprising a serial peripheral interface (SPI) configured to allow a baseband processor access to a telecommunications profile stored in a first security domain and an International Standards Organization (ISO) interface distinct from the serial peripheral interface, the ISO interface configured to allow an application processor access to an application profile stored in a second security domain, the method comprising:

• receiving commands at the serial peripheral interface or the ISO interface;
• enabling accessibility to the application profile when the commands are received at the serial peripheral interface;
• and
• enabling accessibility to the telecommunication profile when the commands are received at the ISO interface.
