In the present days, internet communication is adapting data hiding and cryptography that often needs billions of pseudo random numbers. The Pseudo Random Number Generator (PRNG) is used to fulfill privacy and security needs in most of the applications. In this paper, the PRNG using Lorenz Chaotic Circuit with Carry Select Adder (PRNG-LCC-CSLA) method used to generate the pseudo random numbers. The LCC implemented by using Verilog to generate the pseudo random numbers, and randomness of the LCC results also checked in National Institute of Standards Technology (NIST) testing scheme. Encryption process is implemented by employing binary value of both text and image. Decryption process is implemented by employing same LCC binary value of encrypted data. At last, the Matlab is used to observe the text and image data. The Field Programmable Gate Array (FPGA) results showed how Look Up Table (LUT), slice, flip-flop and frequency improved and Application Specific Integrated Circuit (ASIC) results showed area, power, delay, Area Power Product (APP) and Area Delay Product (ADP) improvements in the PRNG-LCC-CSLA method compared to the existing methods.

In this paper, we designed a three-dimensional chaotic system (3D chaotic system). The continuous-time chaotic system had already been transformed into discrete-time (DT) chaotic system by Euler method. The phase portrait of DT chaotic system had been implemented on an oscilloscope via Altera field programmable gate array (FPGA) DE2-115. A cryptographic system of RGB image security for 3D chaotic system was proposed. There are three features in the encryption system. First, we use the information of plaintext image to produce the initial conditions of chaotic system. Second, the image of the permutation process shuffles the position of pixels in the plaintext image among RGB channels separately. Third, in the diffusion process, the pixels information in the shuffled image had been concealed by the XOR operation. The 3D chaotic encryption system had been also implemented on Altera DE2-115. Then, the cipher image can be obtained through the FPGA and simulated the image by Matlab code.In the security analysis, such as histogram analysis, correlation coefficient analysis, information entropy analysis, differential attack analysis (NPCR and UACI) have been performed in this paper. Experimental results show that the proposed algorithm has better security in comparison with other algorithms.

“…In 1998, the American scholar Fridrich put forward the classical substitution-diffusion architecture for image encryption [2]. This structure subsequently has drawn world-wide concern, and nowadays, most of the image encryption schemes based on chaos adopt this structure and achieved satisfactory encryption effect, such as pixel-level scrambling approaches [3][4][5], enhanced diffusion schemes [6], improved hyper-chaotic sequences [7], linear hyperbolic chaotic system [8], and bit-level confusion methods [9][10][11]. However, only using low dimensional chaotic system to encrypt images cannot guarantee enough security.…”

In order to overcome the difficulty of key management in “one time pad” encryption schemes and also resist the attack of chosen plaintext, a new image encryption algorithm based on chaos and SHA-256 is proposed in this paper. The architecture of confusion and diffusion is adopted. Firstly, the surrounding of a plaintext image is surrounded by a sequence generated from the SHA-256 hash value of the plaintext to ensure that each encrypted result is different. Secondly, the image is scrambled according to the random sequence obtained by adding the disturbance term associated with the plaintext to the chaotic sequence. Third, the cyphertext (plaintext) feedback mechanism of the dynamic index in the diffusion stage is adopted, that is, the location index of the cyphertext (plaintext) used for feedback is dynamic. The above measures can ensure that the algorithm can resist chosen plaintext attacks and can overcome the difficulty of key management in “one time pad” encryption scheme. Also, experimental results such as key space analysis, key sensitivity analysis, differential analysis, histograms, information entropy, and correlation coefficients show that the image encryption algorithm is safe and reliable, and has high application potential.
