ab: Summary: In a threshold cryptosystem, one can send an encrypted message to
    a group without knowing the internal secret sharing policy of the
    group. The encrypted ciphertext can only be deciphered by some users of
    the group according to the secret sharing policy. In this paper, we
    propose solutions to handle the generalized secret sharing policy. In
    addition, we investigate two different models for the group: one with a
    mutually trusted party in the group and the other one without.
