SkyDe: a Skype-based Steganographic Method
Keywords:Information hiding, network steganography, Skype
This paper introduces SkyDe (Skype Hide), a new steganographic methodÂ that utilizes Skype encrypted packets with silence to provide the means for clandestine
communication. It is possible to reuse packets that do not carry voice signals forÂ steganographic purposes because Skype does not use any silence suppression mechanism.
The method’s proof-of-concept implementation and first experimental resultsÂ are presented. They prove that the method is feasible and offers steganographicÂ bandwidth as high as 2.8 kbps.
