    • Effectiveness of crypto-transcoding for H.264/AVC and HEVC video bit-streams. 

      Shah, Rizwan; Ashgar, Mamoona Naveed; Abdullah, Saima; Fleury, Martin; Gohar, Neelam (Springer, 2019-03-22)
      To avoid delays arising from a need to decrypt a video prior to transcoding and then re-encrypt it afterwards, this paper assesses a selective encryption (SE) content protection scheme. The scheme is suited to both recent ...

    • Joint crypto-stego scheme for enhanced image protection with nearest-centroid clustering. 

      Shifa, Amna; Afgan, Muhammad Sher; Asghar, Mamoona Naveed; Fleury, Martin; Memon, Imran; Abdullah, Saima; Rasheed, Nadia (IEEE, 2018-03-12)
      Owing to the exceptional growth of information exchange over open communication channels within the public Internet, confidential transmission of information has become a vital current concern for organizations and ...

    • SLEPX: an efficient lightweight cipher for visual protection of scalable HEVC extension 

      Shah, Rizwan Ali; Asghar, Mamoona Naveed; Abdullah, Saima; Kanwal, Nadia; Fleury, Martin (IEEE, 2020-10-12)
      This paper proposes a lightweight cipher scheme aimed at the scalable extension of the High Efficiency Video Coding (HEVC) codec, referred to as the Scalable HEVC (SHVC) standard. This stream cipher, S ymmetric Cipher for ...
