Lattice-based Zero-Knowledge Proofs: New Techniques for Shorter and Faster Constructions and Applications
lattice-based cryptography zero-knowledge proof CRT packing, ring signature
2019/5/9
We devise new techniques for design and analysis of efficient lattice-based zero-knowledge proofs (ZKP). First, we introduce one-shot proof techniques for non-linear polynomial relations of degree k≥2...
New Techniques for Efficient Trapdoor Functions and Applications
Trapdoor functions Lossy trapdoor functions Computational Diffie-Hellman assumption
2018/11/13
Prior to our work, all constructions of deterministic encryption based even on the stronger DDH assumption incurred a quadratic gap between the ciphertext and plaintext sizes. Moreover, all DDH-based ...
New Techniques for Obfuscating Conjunctions
obfuscation conjunctions learning parity with noise
2018/11/7
We abstract the Bishop et al. scheme to obtain an equivalent yet more efficient "dual'' scheme that can handle conjunctions over exponential size alphabets. This scheme admits a straightforward proof ...
New techniques for multi-value homomorphic evaluation and applications
lwe-based FHE multi-value bootstrapping homomorphic LUT
2018/6/25
In this paper, we propose a new technique to perform several homomorphic operations in one bootstrapping call over a multi-value plaintext space. Our construction relies on the FHEW-based gate bootstr...
In this paper, we consider a scenario where a sender transmits ciphertexts to multiple receivers using a public-key encryption scheme, and at a later point of time, wants to retrieve the plaintexts, w...
A Review of Existing 4-bit Crypto S-box cryptanalysis Techniques and Two New Techniques with 4-bit Boolean Functions for Cryptanalysis of 4-bit Crypto S-boxes
public-key cryptography BFs
2017/12/1
4-bit Linear Relations play an important role in Cryptanalysis of 4-bit Bijective Crypto S-boxes. 4-bit finite differences also a major part of cryptanalysis of 4-bit substitution boxes. Count of exis...
New Techniques for Structural Batch Verification in Bilinear Groups with Applications to Groth-Sahai Proofs
Batch verification bilinear maps Groth-Sahai proofs
2017/8/29
Bilinear groups form the algebraic setting for a multitude of important cryptographic protocols including anonymous credentials, e-cash, e-voting, e-coupon, and loyalty systems. It is typical of such ...
New techniques for trail bounds and application to differential trails in Keccak
differential cryptanalysis trail weight bounds
2017/2/28
We present new techniques to efficiently scan the space of high-probability differential trails in bit-oriented ciphers. Differential trails consist in sequences of state patterns that we represent as...
Land cover classification: Some new techniques, new source data
Environmental variables Global Land Cover AVHRR Satellite Imagery
2016/5/20
Land cover classifications have advanced from using single Landsat Multispectral Scanner scenes to using "full resolution" AVHRR time series. Three current approaches to global land cover study with A...
AC-DC rectifier and storage capacitors take up 25% or more of chip area for cost-sensitive passive RFID tags. In this work, we show that these components can be eliminated by utilizing a RF-only circu...
New Techniques for SPHFs and Efficient One-Round PAKE Protocols
Authenticated Key Exchange Blind Signatures Smooth Projective Hash Functions
2016/1/3
Password-authenticated key exchange (PAKE) protocols allow two players to agree on a shared high entropy secret key, that depends on their own passwords only. Following the Gennaro and Lindell's appro...
This paper presents a novel unifying framework for electronic voting in
the universal composability model that includes a property which is new to universal
composability but well-known to voting sy...
New techniques in nuclear medicine for tumor detection
New techniques nuclear medicine tumor detection Tumor imaging
2010/1/6
Widespread studies on tumor diagnosis has led to the development of techniques with greater sensitivity and improved specificity for detection of occult and small subclinical tumors. Tumor imaging by ...
On Photographs and Phonographs: New Techniques of Recording and their Influence on Mach’s Conception of Knowledge

2008/4/1
I examine some aspects of Mach’s concern for photographs and phonographs. I start with the phonographs, and I examine in particular Mach’s reference to this device in his account of the development of...
