   <dcterms:abstract>Covert channels are a form of hidden communication that may violate the integrity of&#xd;
systems. Since their birth in multilevel security systems in the early 70’s they have evolved&#xd;
considerably, such that new solutions have appeared for computer networks mainly due to&#xd;
vague protocols specifications. We analyze a protocol extensively used today, the Dynamic&#xd;
Host Configuration Protocol (DHCP), in search of new forms of covert communication. From&#xd;
this analysis we observe several features that can be effectively exploited for subliminal data&#xd;
transmission. This results in the implementation of HIDE DHCP, which integrates three&#xd;
covert channels that accommodate to different stealthiness and bandwidth requirements.</dcterms:abstract>
