A Kind of Subliminal Channel Communication Algorithm with Keys
Shun Li · Chinese Journal of Computers · 2003
This paper proposes a new method for establish a subliminal communication channel with keys. The subliminal channel established with this method has wider bandwidth and needs less computation amount. The main results of this paper consist of two parties: it is proved that the languages on different alphabets have same message expression power, and according to above fact and by the transformation between the languages on different alphabets, a model of subliminal channel communication with keys is established. Instantiation of this model can give a practical subliminal channel. The process of instantiation is the process to decide the keys. The results of this paper supply strict theory and practical technology for establishing subliminal channel. These results have some application prospects.
