Decentralized Inner-Product Encryption with Constant-Size Ciphertext

open access: yesApplied Sciences, 2022
With the rise of technology in recent years, more people are studying distributed system architecture, such as the e-government system. The advantage of this architecture is that when a single point of failure occurs, it does not cause the system to be ...

Practical Inner Product Encryption with Constant Private Key

open access: yesApplied 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 encryption from ring learning with errors [PDF]

open access: yesCybersecurity, 2020
The functional encryption scheme designed using the lattice can realize fine-grained encryption and it can resist quantum attacks. Unfortunately, the sizes of the keys and ciphertexts in cryptographic applications based on learning with errors are large,

More Efficient Constructions for Inner-Product Encryption [PDF]

open access: yesLecture 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]

open access: yesLecture 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.

Unbounded Inner-Product Functional Encryption with Succinct Keys [PDF]

open access: yesLecture Notes in Computer Science, 2019
We define the Unbounded Inner-Product functionality in the context of Public-Key Functional Encryption, and introduce schemes that realize it under standard assumptions. In an Unbounded Inner-Product Functional Encryption scheme, a public key allows anyone to encrypt unbounded vectors, that are essentially mappings from Nāˆ— to Zp.

Verifiable Inner Product Encryption Scheme [PDF]

open access: yes, 2020
In the standard setting of functional encryption (FE), we assume both the Central Authority (CA) and the encryptors to run their respective algorithms faithfully. Badrinarayanan et al. [ASIACRYPT 2016] proposed the concept of verifiable FE, which essentially guarantees that dishonest encryptors and authorities, even when colluding together, are not ...

Efficient functional encryption for inner product with simulation-based security

open access: yesCybersecurity, 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]

open access: yesEAI 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 ...
