Abstract：

Cloud　is　a　computing　paradigm　for　allowing　data　owners　to　outsource　their　data　to　enjoy　on-demand　services　and　mitigate　the　burden　of　local　data　storage.　However,　secure　sharing　of　data　via　cloud　remains　an　essential　issue　since　the　cloud　service　provider　is　untrusted.　Fortunately,　asymmetric-key　encryption,　such　as　identity-based　encryption　(IBE)　and　attribute-based　encryption　(ABE),　provides　a　promising　tool　to　offer　data　confidentiality　and　has　been　widely　applied　in　cloud-based　applications.　In　this　paper,　we　summarize　the　common　properties　of　most　of　IBE　and　ABE　and　introduce　a　cryptographic　primitive　called　ElGamal　type　cryptosystem.　This　primitive　can　be　used　to　derive　a　variety　of　ABE　schemes.　To　illustrate　the　feasibility,　we　present　generic　constructions　of　revocable　attribute-based　encryption　and　dual-policy　attribute-based　encryption　with　formal　definitions　and　security　proofs.　By　applying　our　proposed　generic　constructions,　we　also　present　instantiations　of　these　schemes.　Furthermore,　we　demonstrate　the　high　performance　of　the　proposed　schemes　via　experiments.　©　ICST　Institute　for　Computer　Sciences,　Social　Informatics　and　Telecommunications　Engineering　2019.
