Fully homomorphic encryption is a promising crypto primitive to encrypt your data while allowing others to compute on the encrypted data. But there are many well-known problems with fully homomorphic encryption such as CCA security and circuit privacy problem. Despite these problems, there are still many companies are currently using or preparing to use fully homomorphic encryption to build data security applications. It seems that the full homomorphic encryption is very close to practicality…

Towards Secure Big Data Analysis via Fully Homomorphic Encryption Algorithms

It is aimed to anticipate how homomorphic encryption technology will be useful for secure Big Data processing, especially to improve the utility and performance of privacy-preserving machine learning.

Threat Modeling of Cloud based Implementation of Homomorphic Encryption

A novel and one of the early attempts to model such new attack surfaces on the implementation of homomorphic encryption and map them to STRIDE threat model which is proliferously used in the industry.

On the IND-CCA1 Security of FHE Schemes

This paper grouped the SHE schemes into broad categories based on their similarities and underlying hardness problems, and concluded that none of the proposed schemes were IND-CCA1-secure and that the known general constructions all had their shortcomings.

Sequestered Encryption: A Hardware Technique for Comprehensive Data Privacy

This work presents Sequestered Encryption (SE)—a hardware technique for data privacy that sequesters sensitive plaintext data into a small hardware root of trust and encrypts this data in all external microarchitectural structures, thereby rendering secret values inaccessible to software.

Colmade: Collaborative Masking in Auditable Decryption for BFV-based Homomorphic Encryption

This paper proposes a novel collaborative decryption protocol for the Brakerski-Fan-Vercauteren (BFV) homomorphic encryption scheme in a multiparty distributed setting, and puts it to use in…

Usage of Homomorphic Encryption Algorithms in Process Control

Two types of Cryptosystems are described, namely Paillier and Benaloh cryptosystem, and the scheme describing how the cryptos system works, mainly the encryption and decryption algorithms are presented.

Performance Evaluation of Fully Homomorphic Encryption for End-to-End Cryptographic Communication in Multihop Networks

According to the experimental results of this study, a more effective encryption method can be selected and transmitted according to the length of the transmitted message, number of intermediate nodes, and encryption setting.

Fast Vector Oblivious Linear Evaluation from Ring Learning with Errors

This work presents a conceptually simple VOLE protocol that derives its security from a standard assumption, namely Ring Learning with Errors (RLWE), while still achieving concrete efficiency comparable to the fastest VOLE protocols from non-standard coding assumptions.

Can homomorphic encryption be practical?

A proof-of-concept implementation of the recent somewhat homomorphic encryption scheme of Brakerski and Vaikuntanathan, whose security relies on the "ring learning with errors" (Ring LWE) problem, and a number of application-specific optimizations to the encryption scheme, including the ability to convert between different message encodings in a ciphertext.

Simple Encrypted Arithmetic Library - SEAL v2.1

The most recent version (v2.1) of Simple Encrypted Arithmetic Library - SEAL, a homomorphic encryption library developed by Microsoft Research, is introduced, and some of its core functionality is described.

Chosen-Ciphertext Secure Fully Homomorphic Encryption

Three fully homomoprhic encryption FHE schemes that are secure against non-adaptive chosen ciphertext attacks CCA1, and two instantiations of multi-key identity-based FHE: One from LWE in the random oracle model, and one from sub-exponentially secure indistinguishability obfuscation.

Fast Private Set Intersection from Homomorphic Encryption

This work uses fully homomorphic encryption to construct a fast PSI protocol with a small communication overhead that works particularly well when one of the two sets is much smaller than the other, and is secure against semi-honest adversaries.

Somewhat Practical Fully Homomorphic Encryption

This paper port Brakerski’s fully homomorphic scheme based on the Learning With Errors (LWE) problem to the ring-LWE setting, and provides a detailed, but simple analysis of the various homomorphic operations, such as multiplication, relinearisation and bootstrapping.

On Key Recovery Attacks Against Existing Somewhat Homomorphic Encryption Schemes

In his seminal paper at STOC 2009, Gentry left it as a future work to investigate (somewhat) homomorphic encryption schemes with IND-CCA1 security. At SAC 2011, Loftus et al. showed an IND-CCA1…

Labeled PSI from Fully Homomorphic Encryption with Malicious Security

This work builds upon the unbalanced PSI protocol of Chen, Laine, and Rindal in several ways, adds efficient support for arbitrary length items, construct and implement an unbalanced Labeled PSI Protocol with small communication complexity, and strengthens the security model using Oblivious Pseudo-Random Function (OPRF) in a pre-processing phase.

Proceedings of the 3rd ACM workshop on Cloud computing security workshop

The program of the workshop was complemented by three keynote lectures from renowned security experts: Tim Brown, SVP Chief Security Architect & Distinguished Engineer (CA Technologies, Security Business); Charlie Kaufman, Security Architect, Windows Azure (Microsoft); and John Manferdelli, Senior Principal Engineer and co-lead of the Intel Science and Technology Center for Secure Computing (Intel).
