Although both anonymity and covert channels are part of the larger topic of information hiding, there also exists an intrinsic linkage between anonymity and covert channels. This linkage was illustrated in [1]; however, [1] just scratched the surface of the interplay between covert channels and anonymity, without a formal analysis of the related issues. This paper begins the process of formalizing the linkage between anonymity and covert channels via the study of quasi-anonymous channels. We also discuss and contrast some of the existing formal mathematical models of anonymity.
The authors in REF make a series of excellent observations about the relation between covert channels and anonymity systems.
