Abstract: Based on the research of traditional coverting channel, this paper presents a new way to implement coverting channel using the packet length, describes the way as a new mode of coverting channel (LAWB mode) with formal characterization, analyses the mode and experiments it respectively on IPv4 and IPv6 protocol.

Key words: coverting channel, packet length field, formal characterization

摘要: 在传统隐蔽通道模型的基础上,利用数据包的长度域,设计一种基于数据包长度的网络隐蔽通道模型(LAWB模型),给出其形式化描述。对该模型进行了分析,并分别在IPv4和IPv6上对该模型进行了实验。
