In this paper, the authors propose a new chaotic secret key cryptosystem, adapted for image encryption in continuous mode, which is based on the use of two one-dimensional discrete chaotic systems: Bernoulli map and Tent map. The pseudorandom sequences generated by the two maps are characterized by independence of their states, uniformly distributed, so hear integration provides excellent properties of confusion and diffusion, and an important space for the secret key, because it consists of parameters and initial states of the chaotic maps. The security tests results of their cryptosystem are very satisfactory.
