A hardware Trojan real-time detection system and its design method

Abstract

The invention provides a hardware Trojan real-time detection system and a design method thereof. The system includes a Trojan horse probe, a data transmission controller and a safety monitoring kernel. The Trojan horse probe acquires a voltage bypass signal on the internal power constraint line of the integrated circuit chip, and transmits it to the safety monitoring kernel through the data transmission controller for Trojan detection. The method includes implanting Trojan horse probes on the integrated circuit chip and establishing a data transmission controller at the initial stage of design; optimizing the number of Trojan horse probes by using principal component analysis to obtain the optimized coordinates of the Trojan horse probes; optimizing the coordinates of the Trojan horse probes under construction Design and integrate third-party IP cores on the integrated circuit chip layout; establish a security monitoring core, monitor the working status of the IP cores inside the chip in real time, use the support vector machine classification algorithm to identify abnormal behaviors, and detect IP cores containing Trojan horses. The invention can detect and locate the IP core containing the Trojan horse in real time, and can find the behavior of the Trojan horse under the condition of low probability triggering.

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
