• A ciphertext-policy attribute-based encryption scheme with optimized ciphertext size and fast decryption 

      Malluhi, Qutaibah M.; Shikfa, Abdullatif; Trinh, Viet Cuong ( Association for Computing Machinery, Inc , 2017 , Conference Paper)
      We address the problem of ciphertext-policy attribute-based encryption with fine access control, a cryptographic primitive which has many concrete application scenarios such as Pay-TV, e-Health, Cloud Storage and so on. ...
    • A new technique for compacting secret key in attribute-based broadcast encryption 

      Canard, Sébastien; Phan, Duong Hieu; Trinh, Viet Cuong ( Springer Verlag , 2016 , Conference Paper)
      Public-key encryption has been generalized to adapt to more and more practical applications. Broadcast encryption, introduced by Fiat and Naor in 1993, aims for applications in pay-TV or satellite transmission and allows ...
    • An efficient instance hiding scheme 

      Malluhi, Qutaibah M.; Shikfa, Abdullatif; Trinh, Viet Cuong ( Association for Computing Machinery , 2016 , Conference Paper)
      Delegating computation, which is applicable to many practical contexts such as cloud computing or pay-TV system, concerns the task where a computationally weak client wants to securely compute a very complex function f on ...
