  text: We present a new transformation of chosen-plaintext secure predicate encryption
    schemes with public index into chosen-ciphertext secure schemes. Our construction
    requires only a universal one-way hash function and is selectively secure in the
    standard model. The transformation is not generic but can be applied to various
    existing schemes constructed from bilinear groups. Using common structural properties
    of these schemes we provide an efficient and simple transformation without overhead
    in form of one-time signatures or message authentication codes as required in
    the known generic transformations.
