Abstract:
According to one embodiment of the invention, a method for setting permission levels is described. First, an application and digital signature is received by logic performing the permission assessment. Then, a determination is made as to what permission level for accessing resources is available to the application based on the particulars of the digital signature. Herein, the digital signature being signed with a private key corresponding to a first public key identifies that the application is assigned a first level of permissions, while the digital signature being signed with a private key corresponding to a second public key identifies the application is assigned a second level of permissions having greater access to the resources of an electronic device than provided by the first level of permissions.
