Faster homomorphic encryption is not enough: improved heuristic for multiplicative depth minimization of Boolean circuits
somewhat homomorphic encryption multiplicative depth Boolean functions
2019/8/27
In somewhat homomorphic encryption schemes (e.g. B/FV, BGV) the size of ciphertexts and the execution performance of homomorphic operations depends heavily on the multiplicative depth. The multiplicat...
A multi-start heuristic for multiplicative depth minimization of boolean circuits
boolean functions homomorphic encryption multiplicative depth
2017/6/1
In this work we propose a multi-start heuristic which aims at minimizing the multiplicative depth of boolean circuits. The multiplicative depth objective is encountered in the field of homomorphic enc...
How not to Prove Yourself: Pitfalls of the Fiat-Shamir Heuristic and Applications to Helios
fiat-shamir zero-knowledge random oracle model
2016/12/10
This paper is concerned with two variants of the transformation that appear but have not been clearly delineated in existing literature. Both variants start with the prover making a commitment. The st...
Most applicable lattice reduction algorithms used in practice are BKZ (Block-Korkine-Zolotarev) type algorithms as the blockwise generalizations of the LLL algorithm (Lenstra-Lenstra-Lovasz). Its orig...
Heuristic Tool for Linear Cryptanalysis with Applications to CAESAR Candidates
linear cryptanalysis authenticated encryption automated tools
2016/1/27
Differential and linear cryptanalysis are the general purpose
tools to analyze various cryptographic primitives. Both techniques have
in common that they rely on the existence of good differential o...
THE NEW HEURISTIC GUESS AND DETERMINE ATTACK ON SNOW 2.0 STREAM CIPHER
Cryptanalysis Stream cipher Guess Determine attack
2016/1/8
SNOW 2.0 is a word oriented stream cipher that has been selected as a standard stream cipher on ISO/IEC
18033-4. One of the general attacks on the stream ciphers is Guess and Determine attack. Heuris...
Development of a Heuristic Approach for Wayfinding and Navigation in a Street Network as a Geographic Space
GIS Development Networks Decision Support
2015/12/2
The purpose of this study is to explore human wayfinding behavior within a familiar street network in a purely qualitative manner. So, the most significant criteria of making decision in the network i...
Self-calibrating network analysis for panoramic cameras by heuristic simulation
Networks Panoramic Camera Calibration Bundle Additional Parameters
2015/8/24
Linear array CCD-based panoramic cameras have a high potential for measurement applications due to their design in acquiring 360 degree field of views and high information content with up to a Giga-pi...
Remote detection of cerebral pathologies in magnetic resonance imagery: an unsupervised heuristic approach
Remote sensing medical imagery segmentation pattern recognition detection of encephalic lesions
2015/8/24
In this work, the attention has been focused to the field of “medical imaging”. The problem of pattern recognition in remote sensing with medical application has been discussed in order to detect sign...
Heading judgments in minimal environments:The value of a heuristic when invariants are rare
Heading judgments minimal environments heuristic invariants
