Access-Controlled Inner Product Function-Revealing Encryption [PDF]
IACR Communications in CryptologyWe 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.

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
CoRRFunctional 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

Efficient functional encryption for inner product with simulation-based security
Cybersecurity, 2021 Functional encryption (FE) is a novel paradigm for encryption scheme which allows tremendous flexibility in accessing encrypted information. In FE, a user can learn specific function of encrypted messages by restricted functional key and reveal nothing ...

Biometric based Multi-Authority Inner Product Encryption for Electronic Health Record [PDF]
EAI Endorsed Transactions on Pervasive Health and Technology, 2020 INTRODUCTION: Attribute-based encryption enhances the security of electronic health records outsourced to the cloud. At thesame time, single authority attribute based encryption leads to user privacy breech and attribute management complexity.Multi ...

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 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.
