COMPUTING DEVICE COMPRISING AN EXECUTION ENVIRONMENT AND A RESERVED COMPARTMENT WITH REDIRECTION, TO SAID COMPARTMENT, OF REQUESTS BETWEEN THE EXECUTION ENVIRONMENT AND AN EXTERNAL DEVICE, AND COMPUTER SYSTEM COMPRISING SUCH A COMPUTING DEVICE
This computing device (12) comprises an information processing unit (18) and a memory (20) combined with the information processing unit (18) and comprising an operating system (46). The operating system (46) comprises a set of function libraries (50) and an application framework (52) forming an execution environment (56) for executing at least one application (54A,..., 54D), and one kernel (48). The memory (20) further comprises a reserved compartment (60) separate from the execution environment (56), the reserved compartment comprising at least one security function (68, 70, 72, 73). The kernel (48) is further configured so as to redirect, to the reserved compartment (60), a request from the application (54A,..., 54D) to an electronic device (64) external to the computing device (12), in order for said request to be processed by a corresponding security function (70, 73).
