Packet Length Covert Channel Capacity Estimation

摘要

Covert channels lead to hidden data transfer and packet networks provide a lot of mechanisms to construct covert channels. Packet length covert channels are resistant to traffic encryption, but there are some data transfer schemes that are difficult to detect. Therefore investigating of packet length covert channels is quite topical. The purpose of this paper is to examine maximum covert channels capacity based on packet length modulation without countermeasures and with countermeasure random increment of packet length.
