WebConditional proxy re-encryption (CPRE) enables delegation of decryption rights, and is useful in many applications. In this paper, we present a ciphertext-policy attribute based CPRE scheme, together with a formalization of the primitive and its security proof. We further propose applying the scheme for fine-grained encryption of cloud data. WebKeywords: Conditional proxy re-encryption · Learning with errors · Fine-grained control 1 Introduction Proxy re-encryption (PRE) allows a semi-trusted proxy with a re-encryption key to transform a ciphertext intended for Alice (i.e. delegator) to another ciphertext intended for Bob (i.e.delegatee) without revealing the underlying plaintext [5].

WebConditional Proxy Broadcast Re-Encryption (CPBRE), which was proposed by Chu et al. [14], can further reduce the cost incurred by TR-PRE. Speci - cally, CPBRE allows a delegator to delegate the decryption rights of a broadcast encryption to a set of delegatees, and to specify a condition to control the re-encryption power of the proxy. In CPBRE ... WebWe will define universal conditional proxy re-encryption (UCPRE) in Section 3. Our UCPRE allows the proxy to transfer the ciphertext of the delegator under an encryption scheme into the ciphertext of the delegatee under a (possibly different) encryption scheme .
