Patent ID: 8661261

Claim:
A method of access control to a communication interface of an integrated circuit, the method comprising: installing applications in said integrated circuit, intercepting events intended to be transmitted between a first communication interface of the integrated circuit and the installed applications, each intercepted event coming from the first communication interface being intended for transmission to only one of the installed applications, transmitting a first intercepted event intercepted between the first communication interface and a first application of the installed applications only if a first state parameter specific to the first application has a value indicating that the first application is authorized to use the first communication interface, the first event being intended for transmission between the first communication interface and the first application, and updating the first state parameter specific to the first application as a function of a second event of the intercepted events, the second event being intended for transmission between the first communication interface and a second application of the installed applications, the second application being distinct from the first application.
