Practical Inner Product Encryption with Constant Private Key
Applied Sciences, 2020 Inner product encryption, first introduced by Katz et al., is a type of predicate encryption in which a ciphertext and a private key correspond to an attribute vector and a predicate vector, respectively.

(Inner-Product) Functional Encryption with Updatable Ciphertexts. [PDF]
J Cryptol, 2023 AbstractWe propose a novel variant of functional encryption which supports ciphertext updates, dubbed ciphertext-updatable functional encryption. Such a feature further broadens the practical applicability of the functional encryption paradigm and allows for fine-grained access control even after a ciphertext is generated.

More Efficient Constructions for Inner-Product Encryption [PDF]
Lecture Notes in Computer Science, 2016 We propose new constructions for inner product encryption – IPE1 and IPE2, both secure under the eXternal Diffie-Hellman assumption (SXDH) in asymmetric pairing groups. The first scheme has constant-size ciphertexts whereas the second one is weakly attribute hiding. IPE2 is derived from the identity-based encryption scheme of Jutla Roy (Asiacrypt 2013),

On the Practical Security of Inner Product Functional Encryption [PDF]
Lecture Notes in Computer Science, 2015 Functional Encryption (FE) is an exciting new paradigm that extends the notion of public key encryption. In this work we explore the security of Inner Product Functional Encryption schemes with the goal of achieving the highest security against practically feasible attacks.
