Nov 7, 2022 · In a VFE scheme, both ciphertexts and function keys can be verified. The verifiability of VFE requires that: for each ciphertext ct which passes ...
A verifiable random function[MRV99] VRF = (Gen,Eval,Prove,Verify) consists of the following algorithms: • Gen(λ). The setup algorithm takes as input a security ...
Nov 9, 2016 · A verifiable functional encryption scheme is similar to a regular functional encryption scheme with two additional algorithms (\mathsf {VerifyCT} ...
We show that simulation-based verifiable functional encryption is unconditionally impossible even in the most basic setting where there may only be a single key ...
Nov 9, 2023 · Abstract. Joint computation on encrypted data is becoming increasingly crucial with the rise of cloud computing.
The potential applications of FE are numerous and include any setting where there exist designated entities that are entitled to functional views of encrypted ...
In this paper, we propose a SIM-based VFE scheme. To bypass the impossibility result, we introduce a trusted setup assumption.
