  • 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 ...
  • Farajallah, Mousa; Deforges, Olivier; El Assad, Safwan (International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2016-02-01)
    Nonlinear dynamic cryptosystems or chaos-based cryptosystems have been attracting a large amount of research since 1990. The critical aspect of cryptography is to face the growth of communication and to achieve the design ...
  • Farajallah, Mousa; Hamidouche, Wassim; Deforges, Olivier; El Assad, Safwan (2015 IEEE International Conference on Image Processing (ICIP), 2015-09-27)
    In this paper we investigate privacy protection for the HEVC standard based on the tile concept. Tiles in HEVC enable the video to be split into independent rectangular regions. Two solutions are proposed to encrypt the ...
  • Hamidouche, Wassim; Farajallah, Mousa; Raulet, Mickael; Deforges, Olivier; El Assad, Safwan (2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015-04-19)
    In this paper we investigate a selective video encryption in the scalable HEVC extension (SHVC). The SHVC extension encodes the video in several layers corresponding to different spatial and quality representations of the ...
