Research on Non-interactive Construction based on Fuzzy Conditional Proxy Re-encryption

In a conditional proxy re-encryption (C-PRE) scheme, a semi-trusted proxy can transform Alice’s ciphertext into Bob’s ciphertext without learning the underlying plaintext, if the ciphertext satisfies a certain condition. To achieve more fine-grained delegation on conditions, Fang, Wang and Ge introduced the notion of fuzzy conditional proxy re-encryption (FC-PRE), whereby the conditions is viewed a set of descriptive
