Hardware Trojan side channel detection method based on electromagnetism and delay

Abstract

The invention relates to a hardware Trojan detection technology based on electromagnetism and delay, and aims to realize hardware Trojan detection by use of electromagnetism information and delay information leaked by a chip in a working state. According to a hardware Trojan bypass detection method based on electromagnetism and delay of the invention, the corresponding proportional relationship between the current I(tot, m) consumed by a Trojan chip m and the maximum working frequency f(max, m) of a path is as follows: I(tot, m) / f(max, m) is approximately equal to n(tot, m)*k(g)*n(cri, m)*beta(g). A path has n(cri, m) switching tubes, there are n(tot, m) switching tubes working at the moment, and n(tot, m)>=n(tot, g). If a hardware Trojan is inserted onto a current path, n(cri, m)>=n(cri, g), or, n(cri, m)=n(cri, g). If a hardware Trojan is implanted onto the path, the maximum working frequency f(max, m) is proportional to the current I(tot, m) consumed, and identification can be carried out on the basis. The method is mainly applied to an occasion of delay design and manufacture of integrated circuits.

Problems solved by technology

More and more third-party companies and personnel are involved. The chip is not completely autonomous and controllable during the processing process. Attackers can tamper with the original circuit design at any stage to form a malicious circuit. Its area is small and latent. Conventional The detection method is difficult to detect and cannot be cleared. Once the hardware Trojan horse is activated, the attacker will easily obtain the key information in the chip, make the chip work abnormally, and even gain control of the entire information system through the chip
