Access-Controlled Inner Product Function-Revealing Encryption [PDF]

IACR Communications in Cryptology
We extend the concept of access control for functional encryption, introduced by Abdalla et al. (ASIACRYPT 2020), to function-revealing encryption (Joy and Passelègue, SCN 2018). Here "access control" means that function evaluation is only possible when a specified access policy is met.

Inner product functional encryption based on the UOV scheme

Journal of Mathematical Cryptology
We analyze the efficiency and security of the inner product functional encryption (IPFE) protocol introduced in 2021 by Debnath, Mesnager, Dey, and Kundu, specifically when instantiated with UOV.

Improved (Hierarchical) Inner-Product Encryption from Lattices [PDF]

, 2013
Inner-product encryption (IPE) provides fine-grained access control and has attractive applications. Agrawal, Freeman, and Vaikuntanathan (Asiacrypt 2011) proposed the first IPE scheme from lattices by twisting the identity-based encryption (IBE) scheme by Agrawal, Boneh, and Boyen (Eurocrypt 2010).

Privacy-Preserving Traceable Functional Encryption for Inner Product

CoRR
Functional encryption introduces a new paradigm of public key encryption that decryption only reveals the function value of encrypted data. To curb key leakage issues and trace users in FE-IP, a new primitive called traceable functional encryption for inner product (TFE-IP) has been proposed. However, the privacy protection of user's identities has not

Multi-input Inner-Product Functional Encryption from Pairings [PDF]

, 2017
We present a multi-input functional encryption scheme (MIFE) for the inner product functionality based on the k-Linear assumption in prime-order bilinear groups. Our construction works for any polynomial number of encryption slots and achieves security against unbounded collusion, while relying on standard polynomial hardness assumptions.

Predicate encryption for multi‐inner‐products [PDF]

Security and Communication Networks, 2012
ABSTRACTPredicate encryption is a new primitive that supports flexible control over access to encrypted data. We study predicate encryption systems, evaluating a wide class of predicates. Our systems are more expressive than the existing attribute‐hiding systems in the sense that the proposed constructions support not only all existing predicate ...

Functional Encryption for Inner Product Functionality [PDF]

, 2022
Denne oppgaven inneholder konstruksjon av funksjonelle krypteringsalgoritmer for mindre generelle funksjoneller, men som enda er uttrykksfulle nok for praktiske scenarier. Oppgaven er avgrenset til å kun bruke indre produkt som funksjonell. Kryptering av en vector x ved å bruke en vector y som nøkkel, vil kun avsløre .

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.

Inner-Product Matchmaking Encryption: Bilateral Access Control and Beyond Equality

IET Information Security, 2023
We present an inner-product matchmaking encryption (IP-ME) scheme achieving weak privacy and authenticity in prime-order groups under symmetric external Diffie–Hellman (SXDH) assumption in the standard model.
