System for controlling usability of an electronic device (), which host device comprises a processing unit (), the system comprising a first control module (), connected to the processing unit, said first control module comprising a modem () for communicating with a cellular network, and an access circuit () connected to the modem for cellular network access, which access circuit comprises a first secure element (); a second control module () comprising a second secure element (), configured to communicate with the first secure element over a communication link; wherein said access unit is configured to realize a state machine configured to set a usability state dependent on communication between the first secure element and the second secure element, and to control the device in accordance with said usability state.

Modular system for controlling usability of a device

A method and a device for controlling usability of a communication device having a processing unit including a memory for storing computer code, a modem, an access circuit connected to the modem for cellular network authentication and access, and a secure element connected to the access circuit. A boot of the processing unit and the secure element can be initiated at power up of the device. A boot service in the secure element can be executed, and a current state of a state machine in the secure element can be determined. Thereafter, a partition of an operating system can be booted, where the partition is selected dependent on said current state of the state machine.

Method and device for controlling usability of a communication device

The present disclosure provides for methods and devices for enabling distribution of a first security application comprised in the first wireless device to the second wireless device. One method comprises the steps of receiving, in the first wireless device, using a short distance communication technology, a hardware identifier of the second wireless device, sending, from the first wireless device, the hardware identifier and information identifying the first security application to the network node, receiving, in the network node, from the first wireless device, the hardware identifier of the second wireless device and the information identifying the security application and authorizing, in the network node, the second wireless device to receive and/or activate a second security application associated with the first security application of the first wireless device.

Enabling secure application distribution on a (E)UICC using short distance communication techniques

Module () for controlling usability of a processing unit () of a device (), the module comprising a modem () for communicating with a cellular network, and an access circuit () connected to the modem for cellular network authentication and access, which access circuit comprises or is connected to a secure element (), characterized by a state machine configured to control the device in accordance with one of a plurality of usability states, including at least a normal state and an alert state, wherein operation of the processing unit is inhibited in said alert state.
