CCA-Secure Inner-Product Functional Encryption from Projective Hash Functions
Lecture Notes in Computer Science, 2017 International audienceIn an inner-product functional encryption scheme, the plaintexts are vectors and the owner of the secret key can delegate the ability to compute weighted sums of the coefficients of the plaintext of any ciphertext.

Registered (Inner-Product) Functional Encryption
2023Registered encryption (Garg et al. TCC'18) is an emerging paradigm that tackles the key-escrow problem associated with identity-based encryption by replacing the private-key generator with a much weaker entity known as the key curator. The key curator holds no secret information, and is responsible to: (i) update the master public key whenever a new ...

Multi random projection inner product encryption, applications to proximity searchable encryption for the iris biometric [PDF]
Information and Computation, 2023 Biometric databases collect people’s information and allow users to perform proximity searches (finding all records within a bounded distance of the query point) with few cryptographic protections.

Asymmetric Searchable Encryption from Inner Product Encryption
2016Asymmetric searchable encryption(ASE) enables one to retrieve encrypted data stored on an untrusted server without revealing the contents. Now, beyond single keyword search, more and more attention have already been paid to the problem of multi-keyword search. However, existing schemes are mainly based on composite-order bilinear groups. In this paper,

Identity-Based Broadcast Encryption for Inner Products
The Computer Journal, 2018In the identity-based broadcast encryption (IBBE), only these users whose identities are chosen in the ciphertext computing can decrypt the encrypted message. In this paper, we introduce an extension of IBBE, namely Identity-Based Broadcast Encryption for Inner Product (IBBE-IP), where message encryption is replaced by inner product encryption (IPE ...

Simple Functional Encryption Schemes for Inner Products
2015Functional encryption is a new paradigm in public-key encryption that allows users to finely control the amount of information that is revealed by a ciphertext to a given receiver. Recent papers have focused their attention on constructing schemes for general functionalities at expense of efficiency.

Compact Inner Product Encryption from LWE
2018Predicate encryption provides fine-grained access control and has attractive applications. In this paper, We construct an compact inner product encryption scheme from the standard Learning with Errors (LWE) assumption that has compact public-key and achieves weakly attribute-hiding in the standard model.
