Covert channels in IPv6
PET'05: Proceedings of the 5th international conference on Privacy Enhancing TechnologiesPages 147–166https://doi.org/10.1007/11767831_10A covert channel is a communication path that allows transferring information in a way that violates a system security policy. Because of their concealed nature, detecting and preventing covert channels are obligatory security practices. In this paper, ...
