Abstract
Covert channel of the packet ordering is a hot research topic. Encryption
technology is not enough to protect the security of both sides of communication. Covert
channel needs to hide the transmission data and protect content of communication. The
traditional methods are usually to use proxy technology such as tor anonymous tracking
technology to achieve hiding from the communicator. However, because the
establishment of proxy communication needs to consume traffic, the communication
capacity will be reduced, and in recent years, the tor technology often has vulnerabilities
that led to the leakage of secret information. In this paper, the covert channel model of
the packet ordering is applied into the distributed system, and a distributed covert channel
of the packet ordering enhancement model based on data compression (DCCPOEDC) is
proposed. The data compression algorithms are used to reduce the amount of data and
transmission time. The distributed system and data compression algorithms can weaken
the hidden statistical probability of information. Furthermore, they can enhance the
unknowability of the data and weaken the time distribution characteristics of the data
packets. This paper selected a compression algorithm suitable for DCCPOEDC and
analyzed DCCPOEDC from anonymity, transmission efficiency, and transmission
performance. According to the analysis results, it can be seen that DCCPOEDC optimizes
the covert channel of the packet ordering, which saves the transmission time and
improves the concealment compared with the original covert channel.
