Abstract: We consider the problem of constructing a HIBE protocol which is secure in the full model against chosen ciphertext attacks without using random oracle. Known techniques (generic as well as non-generic) convert an (h + 1)-level CPA-secure HIBE protocol into an h-level CCA-secure HIBE protocol. Applied to known constructions, these result in an h-level CCA-secure HIBE whose security degradation is exponential in (h + 1). In this paper, we modify a recent construction of a CPA-secure HIBE to ... (Update)
