Efficient image encryption and authentication scheme based on chaotic sequences

Farajallah, Mousa; Fawaz, Zeinab; El Assad, Safwan; Deforges, Olivier (The 7th International Conference on Emerging Security Information, Systems and Technologies, 2013-08-25)

Many image encryption algorithms based on chaos have been proposed since 1989. Most of them are slow and use a secret key of encryption/decryption independent of the plain image. We introduce a new fast and secure image ...
Lightweight chaos-based cryptosystem for secure images

Fawaz, Zeinab; El Assad, Safwan; Farajallah, Mousa; Ayman, Khalil; Lozi, René; Déforges, Olivier (8th International Conference for Internet Technology and Secured Transactions (ICITST-2013), 2013-12-09)

In the last two decades, several chaos-based cryptosystems have been proposed. Some of them have architecture comprising a layer of permutation and a layer of diffusion and these layers are simultaneously executed in a ...
