In this paper, we study some RSA-based semantically secure encryption schemes (IND-CPA) in the standard model. We first derive the exactly tight one-wayness of Rabin-Paillier encr...

Threshold public-key encryption (TPKE) allows a set of users to decrypt a ciphertext if a given threshold of authorized users cooperate. Existing TPKE schemes suffer from either lo...

We put forward a new paradigm for building hybrid encryption schemes from constrained chosen-ciphertext secure (CCCA) key-encapsulation mechanisms (KEMs) plus authenticated symmet...

In this work, we present HIBE and ABE schemes which are “unbounded” in the sense that the public parameters do not impose additional limitations on the functionality of the sy...
