基于HTTP请求行为的组合式隐蔽信道的构造研究
ON STRUCTURE OF COMBINED COVERT CHANNEL BASED ON HTTP REQUEST BEHAVIOUR
摘要
Abstract
To achieve a proper balance in capacity,reliability and undetectability of the covert channel better,we proposed an HTTP request behaviour-based covert channel.We dynamically assigned the HTTP requests onto multiple HTTP flows and transmitted the hidden information using a way of mathematics combination.Furthermore,by simulating normal HTTP flows we made the undetectability performance of the channel be greatly enhanced.At the same time,the reliable transmission of TCP protocol ensures the transmission process not to be affected by the influence of network status,which guarantees the robustness of the channel.At last we proved through experimental result that the new covert channel has high availability,and is superior to the traditional HTTP-based covert channels on the aspects of transmission rate, transmission accuracy and undetectability.关键词
