Digital image encryption algorithm based on four-dimension chaotic system
Han Feng-ying · 2009
According to the characteristic of higher secrecy of high-dimension chaotic system,a new digital image encryption al-gorithm based on four-dimension chaotic system was proposed.The results and analysis demonstrate that the algorithm has good properties of encryption,a large space of keys,good statistical characteristics,strong anti-noise ability.It can resist for the exhaustion attack and count attack,even if the attacker knows chaotic system that is adopted and encryption algorithm,as long as not knowing the entire key,wanting deciphering the primitive image is also comparatively difficult.It shows that the proposed scheme is of high security.
