Abstract
A wireless communication terminal includes a SIM card and a memory card equipped with respective radio transceivers for allowing a terminal-independent and network-independent radio communication between both cards. Server and client applications on the controllers of the transceivers allow the SIM to manage the memory card. The memory card tries to become connected to the SIM. If connection is successful, the SIM authenticates the memory card and then configures it, in secure mode, to set the access policy to the memory card itself.
Claims18
A method for the management of a peripheral unit by a subscriber identity unit of a terminal of a communication network, comprising:
- providing for radio communication between a first radio transceiver module included in the subscriber identity unit and a second radio transceiver module included in the peripheral unit, the providing comprising establishing a client application on the second transceiver module of the peripheral unit and a server application on the first transceiver module of the subscriber identity unit, for governing the radio communication;
- setting up a connection between said transceiver modules for supporting said radio communication;
- recognising and authenticating said peripheral unit by said subscriber identity unit via said radio communication;
- and
- configuring, in secure mode through a ciphered communication, said peripheral unit by said subscriber identity unit via said radio communication, wherein ciphering in said ciphered communication comprises at least one of:
- a first symmetrical key procedure comprising storing a key on each unit prior to association with a same terminal or respective terminals, and exchanging keys between said units after authentication, via said radio communication;
- a second symmetrical key procedure comprising associating each unit with a same terminal or respective terminals, each unit having no keys stored thereon, and transferring after authentication, one or more keys from a communication network to the subscriber identity unit, and from the subscriber identity unit to the peripheral unit;
- and
- an asymmetrical key procedure comprising storing a private key or a respective private key on each unit prior to association with a terminal or respective terminals and, after authentication, transferring one or more public keys from a communication network to the subscriber identity unit, and from the subscriber identity unit to the peripheral unit.
6 more elements
A peripheral unit comprising a radio transceiver module,
- wherein a control part of said radio transceiver module comprises a client application arranged to communicate with a server application in a control part of a corresponding radio transceiver module included in a subscriber identity unit of a terminal of a communication network, for at least the authentication of said peripheral unit by said subscriber identity unit;
- and
- wherein the peripheral unit is configured, in secure mode through a ciphered communication, by said subscriber identity unit via radio communication, wherein ciphering in said ciphered communication comprises at least one of:
- a first symmetrical key procedure comprising storing a key on each unit prior to association with a same terminal or respective terminals, and exchanging keys between said units after authentication, via said radio communication;
- a second symmetrical key procedure comprising associating each unit with a same terminal or respective terminals, each unit having no keys stored thereon, and transferring after authentication, one or more keys from a communication network to the subscriber identity unit, and from the subscriber identity unit to the peripheral unit;
- and
- an asymmetrical key procedure comprising storing a private key or a respective private key on each unit prior to association with a terminal or respective terminals and, after authentication, transferring one or more public keys from a communication network to the subscriber identity unit, and from the subscriber identity unit to the peripheral unit.
