There Are 10 Types of Vectors (and Polynomials): Efficient Zero-Knowledge Proofs of "One-Hotness" via Polynomials with One Zero
Zero-knowledge efficiency privacy-preserving protocols
2019/8/30
We present a new 4-move special honest-verifier zero-knowledge proof of knowledge system for proving that a vector of Pedersen commitments opens to a so-called "one-hot" vector (i.e., to a vector from...
On the Non-Existence of Short Vectors in Random Module Lattices
Lattice-based cryptography Fiat-Shamir signatures module lattices
2019/8/30
Recently, Lyubashevsky & Seiler (Eurocrypt 2018) showed that small polynomials in the cyclotomic ring Zq[X]/(Xn+1)Zq[X]/(Xn+1), where nn is a power of two, are invertible under special congruence cond...
On the Shortness of Vectors to be found by the Ideal-SVP Quantum Algorithm
Quantum Cryptanalysis Cyclotomic Ideal Lattices
2019/3/4
The hardness of finding short vectors in ideals of cyclotomic number fields (hereafter, Ideal-SVP) can serve as a worst-case assumption for numerous efficient cryptosystems, via the average-case probl...

RE-EMERGING MALARIA VECTORS IN RURAL SAHEL (NOUNA,BURKINA FASO):THE PALUCLIM PROJECT
Tele-epidemiology remote-sensing vectorial risk climate change larvicide’s strategy
2016/11/30
The Paluclim project applied the tele-epidemiology approach, linking climate, environment and public health (CNES, 2008), to rural malaria in Nouna (Burkina Faso). It was to analyze the climate impact...
When the Whole Is Less Than the Sum of Its Parts: How Composition Affects PMI Values in Distributional Semantic Vectors
Semantic Vectors PMI Values
2016/7/7
Distributional semantic models, deriving vector-based word representations from patterns of
word usage in corpora, have many useful applications (Turney and Pantel 2010). Recently, there
has been in...
