| Abstract(in English) | Broadcast encryption with keyword search (BEKS) has been proposed (Attrapadung et al. at ASIACRYPT 2006/Chatterjee-Mukherjee at INDOCRYPT 2018) as a multi-receiver variants of public key encryption with keyword search (PEKS). In BEKS, no receiver anonymity is considered because the test algorithm takes a set of receivers as input, unlike to broadcast encryption. In this paper, we propose a generic construction of BEKS from anonymous and weakly robust 2-level hierarchical identity based encryption (HIBE). The proposed generic construction can be seen as an extension to the Fazio-Perera generic construction of anonymous broadcast encryption (PKC 2012) from anonymous and weakly robust identity based encryption (IBE) and the Boneh et al. generic construction of PEKS (EUROCRYPT 2004) from anonymous IBE. We also demonstrate that the Abdalla et al. generic transformation (TCC 2010/JoC 2018) for providing weak robustness to IBE works for HIBE with an appropriate parameter setting. |
