Abstract: RPKI(Resource Public Key Infrastructure),as a key mechanism for enhancing the security of the BGP(Border Gateway Protocol),directly affects the trustworthiness and resilience of the Internet routing system.Therefore,existing methods for evaluating RPKI deployment based on ROA(Route Origin Authorization) issuance rates are systematically reviewed,and it is pointed out that relying on a single metric makes it difficult to comprehensively reflect the actual deployment effectiveness.Perspectives such as authoritative DNS services,global traffic,and critical asset protection rates are introduced to compensate for these limitations,and the advantages and limitations of each perspective are comparatively analyzed.Analysis based on multidimensional data shows that global RPKI deployment has achieved phased progress,with significant effectiveness in critical infrastructure and core service layers,where more than 70% of authoritative DNS servers and nearly 80% of top global websites have been protected.However,the actual adoption rate of ROV(Route Origin Validation) filtering is only 21.15%,indicating a significant imbalance between resource-side deployment and network-side enforcement,and further advancement of RPKI deployment still requires coordinated efforts in technology,policy,and other aspects.
