“…In 1997, the U.S. NSF (National Science Foundation) established a special working group to study the combination of encryption information technology and error control, which emphasized the importance of joint encryption and error correction technology, but did not give a specific embodiment [2]. In recent years, there were also some studies on encryption and error correction coding techniques [3][4][5][6][7][8][9][10], but most of the studies used two or more steps to complete message encryption and error control, in which the ability of error correction was limited [4]. Because of the excellent performance and wide application of Turbo codes, it was a good candidate to use Turbo codes to design a joint encryption and error correction algorithms.…”

Robust and secure transmission strategy for high quality image through wireless networks is considered a great challenge. However, the majority of encrypted image transmission schemes don't consider well the effect of bit errors occurring during transmission. These errors are due to the factors that affect the information such as noise and multipath propagation. That should be handled by an efficient channel coding scheme. Our proposed scheme is based on combining hybrid chaotic encryption, which is based on twodimensional chaotic maps which is utilized for data security, with an error correction technique based on the Low Density Parity Check (LDPC) code. The LDPC is employed as channel coding for data communication in order to solve the problem of the channel's limited bandwidth and improve throughput. Simulation results show that the proposed scheme achieves a high degree of robustness against channel impairments and wide varieties of attacks as wells as improved reliability of the wireless channel. In addition, LDPC is utilized for error correction in order to solve the limitations of wireless channels.

“…Some researches have been done on the secret communication based on error correction codes, but most of them need two steps for information encryption and error correction [7][8][9]. Gligoroski et al proposed a scheme of joint error correction and encryption [10], but the error correction code in the scheme is based on hard decision and the error-correcting capability is low.…”

This paper proposes a novel encryption method based on Turbo code. In most communication systems, information encryption and error correction are always independent. While joint encryption and error correction codes combine these two processes into one. In order to provide information encryption and error correction simultaneously, we generate a normal random sequence that controls the puncturing mechanism by a secret key in the Turbo encoder. The puncturing mechanism is dynamic and controlled by the secret key. On the other hand, the key-controlled puncturing mechanism deletes the parity bits randomly, which ensures a high error correction capability for the Turbo code. When decoding, only the legal receiver can generate the same normal random sequence using the secret key, then classify and decrypt the received sequence correctly. While for the illegal receivers, because a wrong secret key results in a wrong puncturing mechanism, and the Turbo decoder is sensitive to the puncturing mechanism, they will get a totally wrong decoding result. Meanwhile, this coding scheme also provides good error correction capability for the encrypted information while it is transmitted in a noisy channel. Experimental results show that the proposed method performs well in terms of both security and error-immunity
