基于稳定度的可信AS-IP宣告关系构建方法
Stability-based Reliable AS-IP Mapping Construction Method
摘要
Abstract
Internet Autonomous System ( AS) claims the ownership of its IP address blocks by advertising those blocks in routing system. Prefix hijacking occurs when an AS advertises a prefix not of its own. It is known to be rather challenging to detect and confirm prefix hijacking for Border Gateway Protocol ( BCP) itself cannot tell the invalid mappings of AS and its announced IP prefixes from those valid ones. This paper proposes and implements a stability-based approach to construct reliable AS-IP mappings, which are further used in the detection of prefix hijacking. For each AS-IP mapping, it first builds a time series according to its liveness in a past time window, and then calculates the stability of this sequence to measure the reliability of this mapping. This method is applied to the data related to several large-scale prefix hijacking events. The experiments show that the proposed method can accurately construct AS-IP mappings and effectively detect prefix hijacking events.关键词
