Title:
CCA Secure IB-KEM from the Computational Bilinear Diffie-Hellman Assumption in the Standard Model
Authors: Yu Chen, Liqun Chen, Zongyang Zhang
Abstract:In this paper, we propose several selective-identity chosen-ciphertext attack secure iden- tity based key encapsulation (IB-KEM) schemes that are provably secure under the computational bilinear Diffie-Hellman (CBDH) assumption in the standard model. Our schemes compare favor- ably to previous results in efficiency. With delicate modification, our schemes can be strengthened to be full-identity CCA secure easily.
