Fast Image Encryption Algorithm Based on Multiple Chaotic Maps

This paper presents an efficient encryption algorithm based on 3 chaotic systems. Initially, the Bogdanov chaotic system is used to scramble the original image, in order to complicate the cryptanalysis of the cipher, followed by a number of iterations of encryption with tent map. The parameters of each iteration of the tent map encryption are generated by the chaotic logistic map transformation after going through the transient regime (entering stationarity). The key of the algorithm is composed of the individual keys of each chaotic transformation.
