Privacy-Enhanced Machine Learning with Functional Encryption [PDF]

Lecture Notes in Computer Science, 2019
Functional encryption is a generalization of public-key encryption in which possessing a secret functional key allows one to learn a function of what the ciphertext is encrypting.

Encrypted data ordering with functional encryption

2018 4th International Conference on Recent Advances in Information Technology (RAIT), 2018
For security and privacy, often the user's data are stored on a cloud storage server in an encrypted form. Such data however, are required to be processed in terms of search queries, aggregation, clustering or classification. For better data analysis, the stored data on the server and a result of the processed data should be in lexicographic order. The

Two-Input Functional Encryption for Inner Products from Bilinear Maps [PDF]

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2018
Functional encryption is a new paradigm of public-key encryption that allows a user to compute $f(x)$ on encrypted data $CT(x)$ with a private key $SK_f$ to finely control the revealed information.

Functional Encryption with Oblivious Helper

Proceedings of the 2017 ACM on Asia Conference on Computer and Communications Security, 2017
Functional encryption is a nice tool that bridges the gap between usability and privacy when providing access to huge databases: while being encrypted, aggregated information is available with a fine-tuned control by the owner of the database who can specify the functions he allows users to compute on the data.

A Definitional Framework for Functional Encryption

2015 IEEE 28th Computer Security Foundations Symposium, 2015
Functional encryption (FE) is a powerful generalization of various types of encryption. We investigate how FE can be used by a trusted authority to enforce access-control policies to data stored in an untrusted repository. Intuitively, if (functionally) encrypted data items are put in a publicly-readable repository, the effect of the encryption should ...

Embedding Lemmas for Functional Encryption

2018 International Symposium on Information Theory and Its Applications (ISITA), 2018
Functional encryption is an extension of the ordinary public key encryption where decryption results vary depending on the functions (or key attributes) associated to secret keys. In this paper, we show an embedding lemma for functional encryption, which provides a sufficient criterion for implication from one FE to FE with another function class.

Function-Revealing Encryption

2018
Multi-input functional encryption is a paradigm that allows an authorized user to compute a certain function-and nothing moreover multiple plaintexts given only their encryption. The particular case of two-input functional encryption has very exciting applications, including comparing the relative order of two plaintexts from their encrypted form ...

M-Sel: A Message Selection Functional Encryption from Simple Tools [PDF]

Lecture Notes in Computer Science
In this paper, we put forward a new practical application of Inner-Product Functional Encryption (IPFE) that we call Message Selection functional encryption (M-Sel) which allows users to decrypt selected portions of a ciphertext.
