Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Hardware security is the cornerstone of software security. All approaches to software security are based on the assumption that the hardware is trusted, that the hardware should behave as defined in its manual. At present, in most cases, the function and performance of the hardware are tested during the design process and the delivery process. Since the hardware appears in the user's system as a black box after leaving the factory (unlike a software Tro...

Abstract

The method provides a method for processing asynchronous events by a detection device and the detection device. The method comprises the following steps of: obtaining an instruction position for executing an asynchronous event by a detected processor in a target operation process; and when a task of the target operation process is executed in a manner according with a predefined behavior, executing the asynchronous event at the instruction position, wherein the predefined behavior is a hardware behavior standard of the processor. According to the method, the instruction position for executingthe asynchronous event by the detected processor in the target operation process is obtained, and the asynchronous event is executed at the instruction position, so that the detection device and the detected processor can process same asynchronous events same instruction positions. When the processor carries out safety detection, the method and device can be used for eliminating the influences ofuncertainty factors such as asynchronous events.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for a detection device to process an asynchronous event and a detection device. Background technique [0002] With the rapid development of integrated circuit technology, the scale of digital systems is increasing dramatically. A complex digital system often includes multiple processors, a large number of hardware IP (Intellectual Property, intellectual property) and external devices. In order to improve the efficiency of the digital system, the system will use a large number of asynchronous events in the working process. Due to the uncertainty of asynchronous events, their widespread existence brings great challenges to the security detection of systems and even the verification of digital systems. Contents of the invention [0003] In order to solve the above-mentioned technical problems in the prior art, an embodiment of the present invention provides a detectio...
