摘要
The invention relates to controlling access to at least one material resource of an electronic computing device, shared by a plurality of software tasks to be executed in a predetermined application context, the material resource or resources being managed by a system of operation with executable kernel in privileged execution mode. The access control method is implemented by said operating system kernel and includes a storage of a structure (36) for configuring access to shared hardware resources comprising information (42) relating to authorized transfers. comprising, for each shared hardware resource, at least one indication of transfer authorized between a first task and a second task for use of said resource. Following an execution of a first task using the material resource, this access configuration structure (36) is used to authorize or not an acquisition of said material resource by a second task requiring the use of said material resource.
