Multi-key Authenticated Encryption with Corruptions: Reductions Are Lossy [PDF]
, 2017 We study the security of symmetric encryption schemes in settings with multiple users and realistic adversaries who can adaptively corrupt encryption keys. To avoid confinement to any particular definitional paradigm, we propose a general framework for multi-key security definitions. By appropriate settings of the parameters of the framework, we obtain

Multi-Key Homomorphic Encryption Scheme with Multi-Output Programmable Bootstrapping
Mathematics, 2023 Multi-key Homomorphic Encryption (MKHE) scheme can homomorphically evaluate ciphertexts encrypted by different keys, which can effectively protect the privacy information of data holders in the joint computing of cloud services.

Accelerated Multi-Key Homomorphic Encryption via Automorphism-Based Circuit Bootstrapping
IEEE AccessIn FHEW-like bootstrapping, blind rotation is based on the CMUX Gate (The CMux gate is a controlled selector gate that uses a control input to choose between two data inputs for the output), and blind rotation based on automorphism (A bijective ...

Multi-key and Multi-input Predicate Encryption (for Conjunctions) from Learning with Errors
Journal of CryptologyAbstractWe put forward two natural generalizations of predicate encryption (PE), dubbed multi-key and multi-input PE. More in details, our contributions are threefold. Definitions. We formalize security of multi-key PE and multi-input PE following the standard indistinguishability paradigm, and modeling security both ...

Multikey Verifiable Homomorphic Encryption
IEEE Access, 2022 A homomorphic encryption (HE) scheme is an advanced encryption technology which allows any user receiving ciphertexts to perform computations over them in a public manner. An important application of an HE scheme is a private delegating computation where
