“…Karan Nair et al [11], proposed a new system that to encrypt images chaotic maps are used using the same method as replacements and transformation set-ups. Encryption comprises of seven phases of initial replacement networks, then three levels, each consisting of pixel permutations followed by replacement of values in each image macro block.…”

Recently, security for the image is becoming very important. Image Encryption is the only choice in protecting the digital image by transforming the image into an unreadable format. There are many methods used to protect against unauthorized access. This research proposes a framework for image encryption using Chaos Baker map with SHA-1 algorithm. The Chaotic Baker map is a randomization technique used to make the pixels more shuffled. Key generation is essential part of image encryption, which will be carried out by SHA-1 algorithm. Experimental results show that the proposed method is well suited for high security, key sensitivity and resists various attacks.

The attempts to improve the security of the speech signals are increasing with new encryption schemes. Many recent researches of speech encryption algorithms have been increasingly based on chaotic systems, but the drawbacks of weak security and small key space in one-dimensional chaotic cryptosystems are conspicuous. In this article, a new speech encryption scheme is used. It employs one of the three-dimensional chaotic systems to encrypt a source signal by permutations, thereby confusing the relationship between the cipher signal and the plain signal. A higher-order polynomial equation and rotating matrix are used to strengthen the proposed method. It significantly increases the resistance to attacks. The proposed system has the advantages of smaller iteration times and bigger key space. The system has entertained high-security analysis such as the signal-to-noise ratio, peak signal-to-noise ratio, auto correlation, key sensitivity analysis, number of sample change rate, unified average changing intensity, and histogram analysis. The analysis results illustrate that the proposed system is highly efficient and robust to threats.
