The present invention relates to a method and a system for allowing multiple applications to manage their respective data in a device (100, 200) having a secure environment (104, 204, 211) to which access is strictly controlled. The idea of the invention is that a storage area is allocated (301) within the secure environment (104, 204, 211) of a device (100, 200). The storage area is associated (302) with an identity of an application, the associated identity is stored (303) in the secure environment (104, 204, 211) and access to the storage area is controlled (304) by verifying correspondence between the associated identity and the identity of an accessing application. This is advantageous, since it is possible for the accessing application to read, write and modify objects, such as cryptographic keys, intermediate cryptographic calculation results and passwords, in the allocated storage area. |
