The secret data is encrypted and permutated using the chaos method. Experiments show the good quality of the stego-image and resistant against the various noise attacks (Like Salt and Pepper). At the same time, the proposed algorithm exhibits good encryption speed, less computations and excellent security performance.
In the present era of fast communication, one needs to protect communicated information (message or plain text) from an unauthorized user. The private-key and the public-key are the two well-known cryptosystems [1, 2, 3, 4, 5, 6, and 7] and using these one can keep the secret data securely in such a way that the invader cannot understand what the secret data means.
Keywords: Steganography, Cryptography, Permutation function, and Error correction and detection code.
[...] In the future work, we are planning to design a sophisticated hardware based on this technique which will be targeted to use in highly secure multimedia data transmission applications 6.

The secret data is encrypted and permutated using the chaos method, further encoded the data using the error detection and correction code. Experiments show the good quality of the stego-image and resistant against the various noise attacks (Like Salt and Pepper). At the same time, the proposed algorithm exhibits good encryption speed and less computations, and excellent security performance. [...]
