Generic constructions of integrated PKE and PEKS

In this paper we investigate the topic of integrated public-key encryption (PKE) and public-key encryption with keyword search (PEKS) schemes (PKE-PEKS as shorthand). We first formalize the strongest security notion to date for PKE-PEKS schemes, named joint CCA-security. We then propose two simple constructions of jointly CCA-secure PKEPEKS schemes from anonymous (hierarchical) identity-based encryption schemes. Besides, we also define the notion of consistency for PKE-PEKS schemes, as well as revisit its related notions (including consistency of PEKS schemes, robustness and collision-freeness of IBE schemes), which may be of independent interest. ∗ State Key Laboratory of Information Security, Institute of Information Engineering, Chinese Academy of Sciences, Beijing 100093, China.
