Inner-Product Functional Encryption with Fine-Grained Access Control [PDF]
, 2020 We construct new functional encryption schemes that combine the access control functionality of attribute-based encryption with the possibility of performing linear operations on the encrypted data.

Functional Encryption for Pattern Matching with a Hidden String
Cryptography, 2021 We propose a new functional encryption for pattern matching scheme with a hidden string. In functional encryption for pattern matching (FEPM), access to a message is controlled by its description and a private key that is used to evaluate the description

Transactions on Cryptographic Hardware and Embedded Systems, 2021 Functional encryption is a new paradigm for encryption where decryption does not give the entire plaintext but only some function of it. Functional encryption has great potential in privacy-enhancing technologies but suffers from excessive computational ...

Mergeable Functional Encryption [PDF]
, 2017 In this paper we put forward a new generalization of Functional Encryption (FE) that we call Mergeable FE (mFE). In a mFE system, given a ciphertext \(c_1\) encrypting \(m_1\) and a ciphertext \(c_2\) encrypting \(m_2\), it is possible to produce in an oblivious way a ciphertext encrypting the merged string \(m_1||m_2\) under the security constraint ...

Decentralizing Inner-Product Functional Encryption [PDF]
, 2019 International audienceMulti-client functional encryption (MCFE) is a more flexible variant of functional encryption whose functional decryption involves multiple ciphertexts from different parties.

Deniable Functional Encryption [PDF]
, 2016 Deniable encryption, first introduced by Canetti et al. [14], allows a sender and/or receiver of encrypted communication to produce fake but authentic-looking coins and/or secret keys that "open" the communication to a different message. Here we initiate its study for the more general case of functional encryption FE, as introduced by Boneh et al. [12],

Attribute-based functional encryption on lattices [PDF]
, 2012 We introduce a broad lattice manipulation technique for expressive cryptography, and use it to realize functional encryption for access structures from post-quantum hardness assumptions.

Bootstrapping Homomorphic Encryption via Functional Encryption.
IACR Cryptol. ePrint Arch., 2023 Homomorphic encryption is a central object in modern cryptography, with far-reaching applications. Constructions supporting homomorphic evaluation of arbitrary Boolean circuits have been known for over a decade, based on standard lattice assumptions. However, these constructions are leveled, meaning that they only support circuits up to some a-priori ...

From Single-Input to Multi-Client Inner-Product Functional Encryption [PDF]
, 2019 International audienceWe present a new generic construction of multi-client functional encryption (MCFE) for inner products from single-input functional inner-product encryption and standard pseudorandom functions.
