Ad Hoc Multi-Input Functional Encryption
cryptographic protocols multi input functional encryption
2019/4/8
Consider sources that supply sensitive data to an aggregator. Standard encryption only hides the data from eavesdroppers, but using specialized encryption one can hope to hide the data (to the extent ...
Multi-Input Functional Encryption for Inner Products: Function-Hiding Realizations and Constructions without Pairings
Functional Encryption multi-input inner-product
2017/10/9
We present new constructions of multi-input functional encryption (MIFE) schemes for the inner-product functionality that improve the state of the art solution of Abdalla et al. (Eurocrypt 2017) in tw...
5Gen-C: Multi-input Functional Encryption and Program Obfuscation for Arithmetic Circuits
obfuscation multi-input functional encryption
2017/9/1
Program obfuscation is a powerful security primitive with many applications. White-box cryptography studies a particular subset of program obfuscation targeting keyed pseudorandom functions (PRFs), a ...
Practical Trade-Offs for Multi-Input Functional Encryption
multi-input functional encryption order-revealing encryption
2016/6/20
Multi-input functional encryption is a paradigm that allows an authorized user to compute a certain function ---and nothing more--- over multiple plaintexts given only their encryption. The particular...
Semantically Secure Order-Revealing Encryption: Multi-Input Functional Encryption Without Obfuscation
functional encryption multilinear maps
2016/1/6
Deciding “greater-than” relations among data items just given their encryptions is at the heart of
search algorithms on encrypted data, most notably, non-interactive binary search on encrypted data.
...
We construct a general-purpose multi-input functional encryption scheme in the private-key
setting. Namely, we construct a scheme where a functional key corresponding to a function
f enables a user ...
Multi-Input Functional Encryption with Unbounded-Message Security

2015/12/21
Multi-input functional encryption (MIFE) was introduced by Goldwasser et al. (EUROCRYPT 2014)
as a compelling extension of functional encryption. In MIFE, a receiver is able to compute a joint functi...

The notion of multi-input functional encryption (MI-FE)
was recently introduced by Goldwasser et al. [EUROCRYPT’14] as a
means to non-interactively compute aggregate information on the joint
privat...
\emph{Functional encryption} (FE) is a powerful primitive enabling fine-grained access to encrypted data. In an FE scheme, secret keys (``tokens'') correspond to functions; a user in possession of a c...
We introduce the problem of Multi-Input Functional Encryption, where a secret key SK_f can correspond to an n-ary function f that takes multiple ciphertexts as input. Multi-input functional encryption...
