A new unidirectional single-hop Identity-Based Conditional Proxy Re-Encryption (IBCPRE) scheme that not only captures the property of IBPRE, ...
Suppose an IBPRE scheme without random oracles is se- cure against chosen-plaintext attacks (CPA) based on an IBE scheme (e.g., [24]), and its original ...
Later, the authors in [41] proposed IB-PRE without random oracles. A further proposed scheme in [36] extended the IB-PRE to support a conditional reencryption ...
In this paper, we propose two identity-based proxy re-encryption schemes, which are both proved secure in the standard model. The first one is efficient in both ...
We propose the first construction of an efficient CPRE scheme without pairing, satisfying chosen ciphertext security under the computational Diffie Hellman (CDH) ...
Identity-based conditional proxy re-encryption (IBCPRE) is a type of proxy re-encryption (PRE) scheme in the identity-based public key cryptographic setting.
