2023/12/1
Today, estimating of biological productivity or carbon-depositing ability of forests is going on the global level, and its increase is one of the major factors of climate stabilization. In recent year...
Predicate Encryption from Bilinear Maps and One-Sided Probabilistic Rank
Predicate Encryption Bilinear Maps Probabilistic Rank
2019/9/19
In predicate encryption for a function ff, an authority can create ciphertexts and secret keys which are associated with `attributes'. A user with decryption key KyKy corresponding to attribute yy can...
Unbounded Dynamic Predicate Compositions in Attribute-Based Encryption
attribute-based encryption predicate encryption nested policy
2019/3/4
We present several transformations that combine a set of attribute-based encryption (ABE) schemes for simpler predicates into a new ABE scheme for more expressive composed predicates. Previous proposa...
Function Private Predicate Encryption for Low Min-Entropy Predicates
public-key cryptography ZIPE
2019/1/4
In this work, we propose new predicate encryption schemes for zero inner-product encryption (ZIPE) and non-zero inner-product encryption (NIPE) predicates from prime-order bilinear pairings, which are...
Large Universe Subset Predicate Encryption Based on Static Assumption (without Random Oracle)
Predicate Encryption Adaptive Security Standard Model
2018/12/11
In a recent work, Katz et al. (CANS'17) generalized the notion of Broadcast Encryption to define Subset Predicate Encryption (SPE) that emulates \emph{subset containment} predicate in the encrypted do...
Realizing Chosen Ciphertext Security Generically in Attribute-Based Encryption and Predicate Encryption
Attribute-Based Encryption Predicate Encryption
2018/11/16
We provide generic and black box transformations from any chosen plaintext secure Attribute-Based Encryption (ABE) or One-sided Predicate Encryption system into a chosen ciphertext secure system. Our ...
Adaptively Simulation-Secure Attribute-Hiding Predicate Encryption
predicate encryption partially-hiding simulation-based adaptive security
2018/11/13
This paper demonstrates how to achieve simulation-based strong attribute hiding against adaptive adversaries for predicate encryption (PE) schemes supporting expressive predicate families under standa...
On the Inner Product Predicate and a Generalization of Matching Vector Families
Predicate Encryption Inner Product Encoding Matching Vector Families
2018/11/7
Our main result is a simple lower bound that allows us to show that known encodings for many predicates considered in the cryptographic literature such as greater than and threshold are essentially op...
Multi-client Predicate-only Encryption for Conjunctive Equality Tests
multi-client functional encryption predicate-only encryption privacy-preserving multi-client monitoring
2018/6/5
We propose the first multi-client predicate-only encryption scheme capable of efficiently testing the equality of two encrypted vectors. Our construction can be used for the privacy-preserving monitor...
New Lower Bounds on Predicate Entropy for Function Private Public-Key Predicate Encryption
Predicate Encryption Public-Key Function Privacy
2018/3/6
We present function private public-key predicate encryption schemes from standard cryptographic assumptions, that achieve new lower bounds on the min-entropy of underlying predicate distributions. Exi...
CCA-secure Predicate Encryption from Pair Encoding in Prime Order Groups: Generic and Efficient
Predicate Encryption CCA Security Pair Encoding Scheme
2017/7/6
Attrapadung (Eurocrypt 2014) proposed a generic framework called pair encoding to simplify the design and proof of security of CPA-secure predicate encryption (PE) instantiated in composite order grou...
Subtleties in Security Definitions for Predicate Encryption with Public Index
predicate encryption with public index predicate key-encapsulation mechanism semantic security definition
2017/5/26
We take a critical look at established security definitions for predicate encryption (PE) with public index under chosen-plaintext attack (CPA) and under chosen-ciphertext attack (CCA). In contrast to...
Encrypt-Augment-Recover: Computationally Function Private Predicate Encryption in the Public-Key Setting
Predicate Encryption Public-Key Function Privacy
2017/4/17
We solve the open problem of constructing \emph{computationally function private} public-key predicate encryption schemes. Existing public-key constructions for predicate encryption satisfy a \emph{st...

2017/3/9
Wee (TCC'14) and Attrapadung (Eurocrypt'14) introduced predicate and pair encodings, respectively, as a simple way to construct and analyze attribute-based encryption schemes, or more generally predic...
