摘要
Abstract
A covert channel construction method based on covert information storage distribution is proposed to solve the problem that the existing reference length covert channels are different from legal channels in the channel entropy and length distribution features.The secret information encoded by different encoding modes is converted to binary stream.The distribution probability of bit or bit string acting as secret information in the binary stream is studied.The effect of this probability on traditional length covert channel is analyzed.A new construction model of length covert channel applied by probability distribution statistics is designed.Channel entropy and length distribution are detected.Experimental results prove that compared with the traditional reference length covert channel,the proposed method has better imperceptibility.关键词
