A fast finding method for power Internet of Things equipment vulnerabilities based on page adaptive replacement cache replacement algorithm

This paper aims at the problem that the passive detection and search speed of power Internet of Things equipment is not high. This article proposes a new fast vulnerability finding method, adopts the cache idea, establishes a secondary cache database, and uses the page adaptive replacement cache replacement algorithm idea and mobile The average algorithm is used as a grading rule. This grading rule solves the problems of frequency, timeliness, and noise points. It selects a higher priority CVE and stores it in the first-level cache. The gradient search greatly improves the The search speed of CVE reduces unnecessary waste of computing resources, thus greatly improving the search speed of vulnerabilities.
