Abstract

This article describes the way how some amount of information can be stored into DNS, particularly in the cache of DNS server. Then it can be retrieved back, possibly by another host in the network. Based on this principle we can construct a communication channel, hidden in the usual traffic, or a memory medium. Considering this kind of media, some basic characteristics and limits, like capacity, transfer speed, error rate, persistence of information, etc., are discussed here. Simple algorithm deciding whether a bit in the memory has been set or not was proposed and implemented. Its performance and optimal setting was examined. The results show that under some circumstances error rates about 0.003, when retrieving the information, can be achieved.
