What is hardware Trojan detection?
In the logical test based Hardware Trojan detection, we run different test patterns, what has the vectors. And the monitors, the systems, the output and the behavior. If the system had Hardware trojan, when the trojan is activated, it’s malicious behavior, or malicious payload will observed as it can be caught.
What is a hardware Trojan horse?
Hardware Trojan horses (HTHs) are the malicious altering of hardware specification or implementation in such a way that its functionality is altered under a set of conditions defined by the attacker.
What is a hardware malware?
M. (1) A virus or other malicious software that is attached to a program preloaded on a computer, an external storage drive of USB drive. See malware. (2) A CPU chip in a computer or handheld device that has a built-in back door, enabling an attacker to gain illegal entrance.
Can a virus destroy hardware?
A virus damaging hardware is one of the most widely believed myths in the infosec domain. And, at the same time, it’s the most non-standard one. And it’s not totally a myth, after all. In fact, it’s the one of the most widely believed myths in the infosec world.
How is a hardware trojan different from a HT?
A hardware Trojan is completely characterized by its physical representation and its behavior. The payload of an HT is the entire activity that the Trojan executes when it is triggered. In general, malicious Trojans try to bypass or disable the security fence of a system: It can leak confidential information by radio emission.
Why is it important to know about hardware trojans?
Abstract—Malicious modification of hardware during design or fabrication has emerged as a major security concern. Such tampering (also referred to as Hardware Trojan) causes an integrated circuit (IC) to have altered functional behavior, poten- tially with disastrous consequences in safety-critical applications.
Who are the authors of the hardware trojan paper?

How can a Trojan be triggered on an IC?
Hardware trojans can be triggered in different ways. A trojan can be internally activated, that means it monitors one or more signals inside the IC. The malicious circuitry could wait for a count down logic an attacker added to the chip, so that the trojan awakes after a specific time-span.
