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."}],"citation":{"bibtex":"@article{Blömer_Liske_2014, title={Constructing CCA-secure predicate encapsulation schemes from CPA-secure schemes and universal one-way hash functions}, publisher={Universität Paderborn}, author={Blömer, Johannes and Liske, Gennadij}, year={2014} }","ama":"Blömer J, Liske G.
