摘要
Abstract
The existing network covert channels in the storage category mainly rely on the characteristics of different fields in dif-ferent protocols.Although many protocols such as TCP and UDP have been extensively studied,OSFP is widely used but less re-searched in China.This paper analyzes the Hello message under the OSPF protocol to construct the fields of network covert chan-nels.Three covert channels are constructed using three fields selected from all possible fields,namely Authentication,Router-DeadInterval,and Neighbor,respectively,by adopting random value pattern,value modulation model,and sequence pattern.Channel optimization is achieved by applying microprotocol technology.Finally,the three covert channels are combined into a higher transmission rate covert channel model.Verification shows that this model has certain feasibility and concealment,can pro-vide theoretical support and technical support for the construction of storage-type network covert channels.关键词
