Abstract:
The invention relates to a method in which program information is obtained to an execution environment in an electronic device. The program information comprises at least a program code. A key is computed of the program information and a device specific secret value. The key is used to decrypt program specific state data in the execution environment and to encrypt modified state data after the execution.
