In this paper, discrete-time chaotic systems under single state variable feedback control are studied, and drive-response synchronization is investigated. To that end, ARM platform-based digital color image encryption and decryption using a chaotic stream cipher is designed and implemented, with experimental results demonstrated.

In this paper, a new color image encryption mechanism based on multiple chaotic systems is proposed. In the proposal, two modules are achieved by mixing the features of horizontally and vertically adjacent pixels with the help of adopted multiple chaotic systems, respectively. Then, substitution/confusion is accomplished by generating an intermediate chaotic key stream image based on the adopted chaotic maps. Experimental results show that the proposed scheme is able to manage the trade-offs between the speed performance and security requirements.

Encryption And Decryption

We present the security weakness of encryption algorithm in the form of substitution-permutation network with multiple rounds of permutation and single round of diffusion proposed by W. Zhang et al. The types of chosen-plaintext and chosen-ciphertext attacks are successful against the cryptosystem, and the equivalent versions of keys for encryption and decryption are restored. The security analysis suggests that encryption using substitution-permutation network must be executed more than one encryption round to ensure the security. Our specific examples will demonstrate the cryptanalysis.

Digital Color Images

Digital color images are considered as the most widely used data. They are exchanged frequently on the internet and via email, so an efficient and highly secure method of color image encryption and decryption is needed. Different methods of encryption-decryption are used, but most of them suffer from low efficiency or low-security level or both. In this paper, an efficient and highly secure method of encryption-decryption will be proposed, tested, and implemented. The efficiency parameters will be calculated and compared with other methods’ parameters to prove the efficiency of the proposed method.

Feedback Shift Register

In this paper, a chaos-based image encryption scheme with stream cipher structure is proposed. The key component of the encryption system is a pseudo-random bit generator (PRBG) based on a chaotic map and a linear feedback shift register. The proposed PRBG is not only passes the statistical tests, but also improve the security. The overall design of the image encryption scheme is to be explained while detail cryptanalysis is given.
