基于多重协议的网络隐蔽信道设计与实现
Design and implementation of network covert channel based on multi-protocol
摘要
Abstract
Under the background that the network information security problem is serious increasingly,the communication mechanism of the network covert channel is studied. A method for establishing a network covert channel on the basis of multiple protocols is proposed,in which the communicating parties makes a key agreement according to ICMP protocol,and the covert in-formation is encrypted with the agreed key. The encrypted information is written into the 32 bit serial number field of the TCP protocol. The encrypted session key is written into the 16 bit serial number field of the IP protocol. The method was implemented and tested on the Linux platform. The experimental results show this covert channel has high concealment property and high transmission speed,and is feasible. It provides theoretical basis and technical support for the prevention of malicious attacks.关键词
