Multilinear Map via Scale-Invariant FHE: Enhancing Security and Efficiency
public-key cryptography multilinear maps
2015/12/22
Cryptographic multilinear map is a useful tool for constructing numerous secure protocols
and Graded Encoding System (GES) is an approximate concept of multilinear map. In multilinear
map context, t...
Oblivious Parallel RAM: Improved Efficiency and Generic Constructions
Cryptographic Protocols Oblivious RAM
2015/12/21
Oblivious RAM (ORAM) garbles read/write operations by a
client (to access a remote storage server or a random-access memory) so
that an adversary observing the garbled access sequence cannot infer a...
On the Efficiency of FHE-based Private Queries
Encrypted databases Homomorphic encryption Private queries
2015/12/18
Private query processing is a very attractive problem in the fields of both cryptography
and databases. In this work, we restrict our attention to the efficiency aspect of the problem,
particularly ...
Linear regression-based methods have been proposed as efficient means of characterising device leakage in the training phases of profiled side-channel attacks. Empirical comparisons between these and ...
Self-Updatable Encryption: Time Constrained Access Control with Hidden Attributes and Better Efficiency
Attribute-based encryption Predicate encryption
2014/3/6
Revocation and key evolving paradigms are central issues in cryptography, and in PKI in particular. A novel concern related to these areas was raised in the recent work of Sahai, Seyalioglu, and Water...
Improving security and efficiency for multi-authority access control system in cloud storage
Attribute-level revocation
2014/3/6
Multi-Authority Attribute-Based Encryption (MA-ABE) is an emerging cryptographic primitive for enforcing fine-grained attribute-based access control on the outsourced data in cloud storage. However, m...
Adaptively Secure Broadcast Encryption under Standard Assumptions with Better Efficiency
Public-key encryption Broadcast encryption
2014/3/11
In this paper, we present an efficient public-key broadcast encryption (PKBE) scheme with sub-linear size of public keys, private keys, and ciphertexts and prove its adaptive security under standard a...
Comparing the Pairing Efficiency over Composite-Order and Prime-Order Elliptic Curves
implementation Tate pairing optimal ate pairing software implementation composite-order group
2013/4/18
We provide software implementation timings for pairings over composite-order and prime-order elliptic curves. Composite orders must be large enough to be infeasible to factor. They are modulus of 2 up...
Classification of High-Order Boolean Masking Schemes and Improvements of their Efficiency
implementation / High-Order Masking High-Order Correlation Power Analysis (HO-CPA) High-Order CPA Immunity ($\mathsf{HCI}$) Mutual Information Metric (MIM)
2012/3/26
This article provides an in-depth study of high-order (HO) Boolean masking countermeasure against side-channel attacks. We introduce the notion of HO-CPA immunity as a metric to characterize a leakage...
In recent work, Ishai, Prabhakaran and Sahai (CRYPTO 2008) presented a new compiler (hereafter the IPS compiler) for constructing protocols that are secure in the presence of malicious adversaries wit...
On the Efficiency of Bit Commitment Reductions
secure two-party computation bit commitment string commitment oblivious transfer noisy channel information theory
2012/3/27
Two fundamental building blocks of secure two-party computation are oblivious transfer and bit commitment. While there exist unconditionally secure implementations of oblivious transfer from noisy cor...
Cryptography for Efficiency: Authenticated Data Structures Based on Lattices and Parallel Online Memory Checking
