Title:
Efficient CCA-secure Threshold Public-Key Encryption Scheme
Authors: Xi-Jun Lin, Lin Sun
Abstract:In threshold public-key encryption, the decryption key is divided into n shares, each one of which is given to a different decryption user in order to avoid single points of failure. In this study, we propose a simple and efficient non-interactive threshold public-key encryption scheme by using the hashed Diffie-Hellman assumption in bilinear groups. Compared with the other related constructions, the proposed scheme is more efficient.
