Optimal Bounded-Collusion Secure Functional Encryption
Bounded-Key Functional Encryption Correlated Garbling
2019/3/22
We construct private-key and public-key functional encryption schemes secure against adversaries that corrupt an a-priori bounded number of users and obtain their functional keys, from minimal assumpt...
Impossibility of Simulation Secure Functional Encryption Even with Random Oracles
functional encryption simulation-based security random oracle model
2016/12/8
In this work we study the feasibility of achieving simulation security in functional encryption (FE) in the
random oracle model. Our main result is negative in that we give a functionality for which ...
Adaptively Secure Functional Encryption for Finite Languages from DLIN Assumption
Functional encryption Attribute-based encryption DFA
2016/1/23
In this paper, we present Functional Encryption (FE) schemes for finite languages from standard static assumption, viz., Decisional Linear (DLIN) assumption. These finite languages are described by ...
Dual System Encryption via Doubly Selective Security: Framework, Fully-secure Functional Encryption for Regular Languages, and More
Dual system encryption Functional encryption for regular languages Attribute-based encryption
2016/1/9
Dual system encryption techniques introduced by Waters in Crypto’09 are powerful approaches
for constructing fully secure functional encryption (FE) for many predicates. However,
there are still som...
A Punctured Programming Approach to Adaptively Secure Functional Encryption
public-key cryptography Functional Encryption Obfuscation
2016/1/8
We propose the first construction for achieving adaptively secure functional encryption (FE) for poly-sized circuits (without complexity leveraging) from indistinguishability obfuscation (iO). Our red...
Simulation-Based Secure Functional Encryption in the Random Oracle Model
Functional Encryption Random Oracle Model Simulation-Based Security
2016/1/6
One of the main lines of research in functional encryption (FE) has consisted in studying the security notions for FE and their achievability. This study was initiated by [Boneh et al. -- TCC'11, O'Ne...
Generic Conversions from CPA to CCA secure Functional Encryption
Functional encryption Predicate encryption Delegation
2015/12/30
In 2004, Canetti-Halevi-Katz and later Boneh-Katz showed
generic CCA-secure PKE constructions from a CPA-secure IBE. Goyal
et al. in 2006 further extended the aforementioned idea implicitly to provi...
Fully Secure Functional Encryption for Inner Products, from Standard Assumptions
Functional encryption adaptive security standard assumptions
2015/12/29
Functional encryption is a modern public-key paradigm where
a master secret key can be used to derive sub-keys SKF associated
with certain functions F in such a way that the decryption operation
re...
Fully Secure Functional Encryption with General Relations from the Decisional Linear Assumption
Functional Encryption Attribute-Based Encryption Predicate Encryption
2010/11/10
This paper presents a fully secure functional encryption scheme for a wide class of relations, that are specified by non-monotone access structures combined with inner-product relations. The security ...
Fully Secure Functional Encryption：Attribute-Based Encryption and (Hierarchical) Inner Product Encryption
Secure Functional Encryption Attribute-Based Encryption Inner Product Encryption
2010/3/16
In this paper, we present two fully secure functional encryption schemes. Our rst result
is a fully secure attribute-based encryption (ABE) scheme. Previous constructions of ABE
were only proven to...
