In this paper, we coin the notion of dual receiver proxy re-encryption. In dual receiver proxy re-encryption, the delegator's ciphertext is re-encrypted using a single re-encryption key such that it can be decrypted by two-independent delegatees. To realize the dual receiver re-encryption, the traditional proxy re-encryption scheme requires two re-encryption keys to be generated, one for each delegatee and re-encryption should be done independently producing independent ciphertexts for each delegatee. This approach is computationally inefficient and requires larger bandwidth for ciphertext transmission. In the proposed dual receiver proxy re-encryption scheme based on bilinear mapping, only a single re-encryption key, only one re-encryption operation and only one ciphertext enables two delegatees to decrypt the common ciphertext independently. We prove the IND-CPA security of the proposed dual receiver proxy re-encryption scheme based on the DDH assumption. The proposed dual receiver proxy re-encryption scheme can be used in applications where a common ciphertext needs to be re-encrypted for two delegatees. |
