Group-based Proxy Re-encryption scheme

Chunbo Ma, Jun Ao, and Jianhua Li

Abstract

Recently, proxy re-encryption scheme received much attention. In this paper, we propose a proxy re-encryption used for divert ciphertext from one group to another. The scheme is bidirectional and any member can independently decrypt the ciphertexts encrypted to its group. We discuss the security of the proposed scheme and show that our scheme withstands chosen ciphertext attack in standard model.
