Abstract
The present invention relates to a method for executing a security critical activity in a security device (40), wherein the security critical activity is executed with user involvement. Each security critical activity is divided into a number of situations/actions, belonging either to a proxy letter group or a user involvement group. The processor (42) of the security device (40) starts the execution of an action of a security critical activity, and then checks if this situation/action can be handled by a proxy letter or shall be handled by a user. If the user or the proxy letter grants the situation/action the execution of the action is continued and ended. This is repeated until all actions of the security critical activity have been executed. If neither the user nor the proxy letter grants the situation/action the execution of the security critical activity will be stopped.
