Abstract

Code obfuscation has been well developed as mitigated endogenous security technology, to effectively resist MATE attacks (e.g.reverse engineering).And it also has important value for the reasonable metrics of code obfuscation effect.Since symbolic execution is widely used in anti-obfuscation attacks, metrics for code obfuscation resilience can refer to the efforts of generating input test set for executing all program paths.However, some adversarial techniques could reduce the symbol execution efficiency significantly based on the nested structure of the program and increase the error of the resilience reference.To solve the above problems, a metrics for code obfuscation was proposed based on symbolic execution and N-scope complexity.The obfuscation resilience was defined with symbolic execution time and obfuscation potency was defined based on the proposed N-scope complexity for better robustness in measuring the resilience of multi-nested structure programs.Furthermore, the correlation analysis of obfuscation effect was proposed and the effect was quantified by symbolic execution and control flow diagram extraction of programs.Over 4000 obfuscated programs from 3 open-sourced assemblies were evaluated with proposed metrics in the experiment, which indicated the generalization performance and practicality of the metrics.And an example of this metrics application was presented in a simulated obfuscation scenario which provided references of obfuscation technology metrics and obfuscation configuration for obfuscation users.

Abstract

High-performance photodetectors with the detection capability of linearly polarized light have broad applications in both military and civilian fields. Quasi-one-dimensional ZrS3as an emerging anisotropic two-dimensional material has come under the spotlight owing to its intriguing properties. However, the performance of the ZrS3photodetector is seriously restricted by its low responsivity. Herein, a novel high-performance photodetector based on the van der Waals ZrS3/MoS2heterostructure is proposed. Attributed to the charge trapping-assisted photogating effect, interlayer carrier transitions, and fast spatial separation of the photogenerated electron–hole pairs, the device displays superior photoresponse characteristics ranging from the ultraviolet to the visible spectrum in terms of high responsivity up to 212 A/W, an extraordinary external quantum efficiency of 8.5 × 104%, and a prompt rise/decay time of 0.19/0.38 ms. In addition, owing to the profound birefringence and dichroism effects in ZrS3together with strong light–matter interactions in the heterostructure, profound linear-polarization sensitivity is demonstrated with a dichroic ratio of about 2.8. Overall, this photodetector not only is integrated with the excellent properties of ZrS3and monolayer MoS2but also further enhances the advantages through interlayer couplings, which demonstrate the strong potential of the ZrS3-based devices for high-performance, ultrafast, and polarization-sensitive photodetection.
