摘　　要：隐蔽通道是网络中一种常用的通信手段，它可以在网络中传输隐蔽数据，且常用于网络攻击。对ICMP协议进行分析后．构建了基于ICMP协议的隐蔽通道，并在C＋＋Builder 6．0下实现。对程序运行结果进行了分析，给出了一些对隐蔽通道的防范措施。Covert Channel network is a common means of communication,it can be hidden in the network data transmission, and commonly used in network attacks.ICMP protocol on the analysis,the ICMP Based on the protocol covert channel,and C＋＋ Builder 6.0 to achieve. Operation results of the process were analyzed, presented some of the covert channel preventive measures.
