Hardware Trojan real-time detection system and design method thereof

Abstract

The invention provides a hardware Trojan horse real-time detection system and a design method thereof. The system comprises Trojan probes, a data transmission controller and a safety monitoring kernel. The Trojan probes acquire voltage bypass signals on power supply constraint lines inside an integrated circuit chip, and transmit the voltage bypass signals to the safety monitoring kernel for Trojan detection through the data transmission controller. The method comprises the following steps: the Trojan probes are implanted on the integrated circuit chip at the initial design stage to establishthe data transmission controller; a principal component analysis method is used to optimize the number of the Trojan probes and the optimal coordinates of the Trojan probes are obtained; a third-partyIP core is designed and integrated on the integrated circuit chip layout with the Trojan probe optimal coordinates; a security monitoring kernel is established to monitor the working state of IP corein real time; the abnormal behavior is identified by a support vector machine classification algorithm and the IP core with the Trojan is detected. The invention can detect and locate the IP core containing the Trojan in real time, and can find the Trojan behavior triggered under the low probability condition.

Description

technical field [0001] The invention belongs to the field of integrated circuit and chip safety research and design, in particular to a hardware Trojan real-time monitoring system and a design method thereof. Background technique [0002] In the VLSI design process, in order to reduce design complexity, improve design reusability and shorten the design cycle, each functional module usually directly selects the existing IP core (Intellectual Property core, also known as intellectual property module) ) for integration. IP cores are divided into soft core IP, hard core IP, and solid core IP. In reality, most IP cores are submitted to integrated circuit designers in the form of non-open source hard cores and solid cores. A large number of these IP cores are used in the design of logical computing devices such as processors, microcontrollers, and storage devices. A typical system-on-chip usually needs to use dozens to hundreds of independent IP cores, and 70% of the IP cores are...

Problems solved by technology

[0005] The present invention aims at the problems existing in the current IP core detection technology, and proposes a hardware Trojan horse real-time detection system and its design method to solve the problem that some Trojan horses are difficult to detect in the traditional hardware Trojan horse detection method. Real-time detection of the working status of the IP core inside the chip during the running phase can overcome the above two shortcomings of the traditional hardware Trojan detection method
