Zhang Yu-li · Journal of Guangzhou University · 2006
Two subliminal-free methods named weak(strong) subliminal-free have been proposed in this paper for the first time.The first method can only free the subliminal information on some probability,and the second can free all.Moreover,we have embedded a subliminal channel in NSS system,and also give its subliminal-free method.The NSS is a new digital signature scheme introduced in 2001.The paper is also the first one on the construction of subliminal channel in NSS.
