Hardware attack defense method and device based on TDC module, and electronic equipment

Abstract

The invention discloses a hardware attack defense method and device based on a TDC module, and electronic equipment. The method comprises the following steps: inputting a configurable clock source into the TDC module, so as to enable the TDC module to output a delay clock signal group and a sampling signal through a delay unit chain; inputting the sampling signal into a pseudo-random number generator to enable the pseudo-random number generator to process the sampling signal, and outputting a chip selection signal; respectively using the chip selection signal and the delay clock signal group as a chip selection signal and an input signal of a multiplexer to be input into the multiplexer, enabling the multiplexer to output a misplaced clock signal, and using the misplaced clock signal as an input clock of an IP core needing to be protected; and presetting a threshold parameter for the TDC module, comparing the sampling signal and the preset threshold parameter, and if the sampling signal exceeds the range of the preset threshold, triggering the TDC module to output an early warning signal.

Description

technical field [0001] The present application relates to the technical field of fault attack analysis, in particular to a TDC module-based hardware attack defense method, device, and electronic equipment. Background technique [0002] With the rapid development of machine learning, stronger computing power is now required to support more and more complex network structures. Due to its high parallel computing power and high flexibility, FPGAs are widely used as acceleration units in cloud data centers. . At the same time, more and more cloud service providers are beginning to provide enterprise-oriented FaaS and AaaS services. Through these services, developers can use cloud FPGA resources to quickly realize the development of custom IP and realize profitability. In order to further utilize FPGA resources in the cloud, the industry proposes a multi-tenant scenario. In this scenario, the resources on the FPGA are dynamically allocated to each user, and this method can grea...
