Abstract

The present invention relates to a method and a device (101) for enabling time-controlled operation of an object (104). A basic idea of the present invention is to control, in a deterministic manner, operation time of an object, e.g. an electronic appliance such as a mobile phone or a computer, a software program such as an echo-cancellation algorithm implemented in a mobile phone or a piece of executable code implemented in a computer, etc, resulting in a physical output signal (105). The manner in which the operation time is controlled should be obfuscated such that a malicious intruder cannot identify the control iunction that determines the operation time of the object by means of probing and/or reverse engineering the object to eliminate, remove or bypass the control function.
