Claim Text:
1. An electronic device, comprising: a communication interface; a processor, which is configured to store and process secret information and to communicate with a host device via the communication interface; and an environmental detector, which is configured to detect a change, relative to a baseline, in an operating environment of the electronic device, and in response to the detected change, to initiate a secure communication between the processor and the host device when the detected change is in a predefined first range, and to invoke a countermeasure against tampering with the device when the detected change is in a predefined second range, disjoint from the first range, the environmental detector being operative to issue to the processor, when the detected change is in the predefined first range, an instruction to conduct the secure communication with the host device via the communication interface, the host device being operative to actuate an environmental signal generator to generate changes that are within the predefined first range, relative to the baseline, in the operating environment of the electronic device, wherein the change detected by the environmental detector comprises at least one of the following:
