Passing Hidden Information Using Attack Detectors |
摘要 |
An electronic device (22) includes a communication interface (36) and a processor (30), which is configured to store and process secret information and to communicate with a host device (24) via the communication interface. An environmental detector (38) 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. |

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. |
