摘要：
Recently, proxy re-encryption scheme received much attention. A proxy re-encryption used for divert ciphertext from one group to another without revealing underlying plaintext is proposed in this paper. The scheme is bidirectional and any member can independently decrypt the ciphertext encrypted to its group. The security of the proposed scheme is discussed and proofs are given to show that the scheme withstands chosen ciphertext attack in standard model.
