“…The lack of security of the encryption method proposed in [21] is made evident, since it can be broken without knowing its parameter values and even without knowing the transmitter's precise structure. A new method that can retrieve the plaintext and determine part of the key directly from the ciphertext has been devised.…”

“…Matthews proposed a chaotic encryption algorithm in 1989 [9]. Since then, researches of image encryption technology which are based on chaotic systems are increased [10][11][12][13][14]. These methods have high-level efficiency but also weakness, such as small key space, weak security and complexity to overcome these drawbacks.…”

Abstract-In this article, a new transmission system of encrypted image based on novel chaotic system and SPIHT technique is proposed. This chaotic system is made up of two chaotic systems already developed: the discrete-time modified Henon chaotic system and the continuous-time Colpitts one. The transmission system is designed to take profit of two advantages. The first is the use of a robust and standard algorithm (SPIHT) which is appropriate to the digital transmission. The second is to introduce farther complexity of the encryption using the chaotic system over secure channel. Through these two advantages, our purpose is to obtain a robust system against pirate attacks. Cryptanalysis and various experiments have been carried out and the results were reported in this paper, which demonstrate the feasibility and flexibility of the proposed scheme.

“…The insecurity was shown for other methods, in particular, for CSK [2,3], parametric modulation [2], and inclusion method [2]. Modification to these methods [4,5] have also been proposed but to no avail [6,7]. Other proposed methods based on the projective synchronization [8], phase synchronization [9], generalized synchronized were broken as well [10,11].…”

In this paper, a modified chaotic shift keying method is proposed to transmit digital bits securely over a communication channel. The scheme is based upon encrypting the digital bits 0 and 1 into infinite levels by applying the keystream such that there is no recognisable pattern in the encoded transmitted signal. The encoded transmitting signal generated is shown to resist popular attack method therefore realizing a secure and trustworthy digital communication system.
