“…The wide range of cryptographic algorithms started to publicize for decades by DES (Data Encryption Standard) then standardized, after 2000, as AES (Advanced Encryption Standard) [12]. AES (Advanced Encryption Standard) is a symmetric-key algorithm [12]. Initially, when the algorithms first started to appear, it was known as the Rijndael algorithm.…”

In this paper, we propose a modification for security authentication systems in mobile devices. Our enhancement is designed to secure information transformation over the internet by combining hash, cryptography and steganography mechanisms. We used the combination for authentication, to secure mobile computing to transfer data in a trusted manner. The proposed work will use hash function to store the secret password to provide increased security. The hashed password is encrypted using AES encryption then hidden inside an image to be called back for authentication whenever needed. The security services provided by this combination mechanisms can assure authenticity, confidentiality, and integrity. Results and comparisons to different options of available mobile computing methods proved that our proposed technique is a promising research direction for real mobile security.

“…On the other hand, the public key algorithm uses a pair of keys (public key and private key) to perform data encryption and decryption. The advantage of the public key cryptosystem is that providing public keys is easier than distributing secret keys securely [2]. However, the execution of public key algorithms is much slower than the execution of symmetric key algorithms.…”

This paper presents the hardware design of a high performance cryptosystem for video streaming application. Our proposed system is the combination of two cryptographic algorithms, symmetric key algorithm and asymmetric key algorithm (also called public key algorithm) to take their benefits. The symmetric key algorithm (ZUC) is used to encrypt/decrypt video, and the public key algorithm (RSA) performs the encryption/ decryption for the secret key. This architecture has high performance, including high security and high processing bit rate. High security is achieved due to the ease of key distribution of the asymmetric key cryptosystem and the secret key can be easily changed. The high processing bit rate of video encryption/decryption is the result of the high speed of encryption/decryption of the symmetric key algorithm. The H.264 video decoder is also integrated into this system to test the functionality of the proposed cryptosystem. This system is implemented in Verilog-HDL, simulated by using the ModelSim simulator and evaluated by using Altera Stratix IV-based Development Kit. The speed of video decryption achieves up to 4.0 Gbps at the operating frequency of 125 MHz, which satisfies applications with high bandwidth requirement such as video streaming.

“…In literature [15], chaotic sequences are used to construct the encryption matrix, but the encryption method is relatively simple. Other research [16] suggests constructing the Hill encryption matrix by an elliptic curve, but the algorithm is too complex.…”

Based on Hill matrix and dynamic DNA encoding, an image encryption method is proposed. First, this method combines an elliptic curve with a hyper-chaos sequence to fabricate the Hill cipher matrix, and the plaintext image is permuted and encrypted. Second, the dynamic DNA encoding technique is applied to diffuse the gray values of this plaintext image. Finally, hyper-chaos sequences are employed to complete the confusion and diffusion of the image. The experimental results show that the presented method can not only defend against brute-force attacks and statistical attacks but also resist plaintext attacks; in addition, the method has the merits of fast encryption speed, good encryption effects, and easy implementation.
