Subliminal channel is a covert communication channel that can securely exchange secret information. By analyzing the communication protocols and encryption algorithms of two popular instant messaging systems QQ and Skype, this paper devotes the efforts to find whether they satisfy the condition of establishing subliminal channel or not. The broad-band subliminal channel can be established in Skype and QQ messages. Therefore, two subliminal channel schemes are proposed to embed and extract subliminal information. Finally, performances of the proposed subliminal channels are compared with those of the ones based on ElGamal digital signature and Newton channel. Experimental results and theoretical analysis show that they are easy to be implemented with large bandwidth and execute fast.
