    Robust threshold schemes based on the Chinese remainder theorem
    (Springer, 2008-06) Kaya, Kamer; Selçuk, Ali Aydın
    Recently, Chinese Remainder Theorem (CRT) based function sharing schemes are proposed in the literature. In this paper, we investigate how a CRT-based threshold scheme can be enhanced with the robustness property. To the best of our knowledge, these are the first robust threshold cryptosystems based on a CRT-based secret sharing. © 2008 Springer-Verlag Berlin Heidelberg.

    Threshold broadcast encryption with reduced complexity
    (IEEE, 2007-11) Kaşkaloǧlu, K.; Kaya, Kamer; Selçuk, Ali Aydın
    Threshold Broadcast Encryption (TBE) is a promising extension of threshold cryptography with its advantages over traditional threshold cryptosystems, such as eliminating the need of a trusted party, the ability of setting up the system by individual users independently and the ability of choosing the threshold parameter and the group of privileged receivers at the time of encryption. An ElGamal-based solution for TBE was proposed by Ghodosi et al. In this paper, we propose an improved ElGamal-based TBE scheme with reduced transmission cost. ©2007 IEEE.
