Query: Steganography using the Extensible Messaging and Presence Protocol
  (XMPP)   We present here the first work to propose different mechanisms for hiding
data in the Extensible Messaging and Presence Protocol (XMPP). This is a very
popular instant messaging protocol used by many messaging platforms such as
Google Talk, Cisco, LiveJournal and many others. Our paper describes how to
send a secret message from one XMPP client to another, without raising the
suspicion of any intermediaries. The methods described primarily focus on using
the underlying protocol as a means for steganography, unlike other related
works that try to hide data in the content of instant messages. In doing so, we
provide a more robust means of data hiding and additionally offer some
preliminary analysis of its general security, in particular against
entropic-based steganalysis.
