获得准确、连续性好的电场分布数据是开展时间投影电离室（TPC）探测器模拟计算的重要基础。本文基于常用的有限元程序ANSYS，实现了TPC探测器3D电场计算及电场数据在探测器模拟程序GARFIELD中的读入。采用Quadratic Shepard插值法，对电场数据进行了插值处理。计算结果表明，Quadratic Shepard插值法能在周围插值点分布极端不均匀情况下获得较为准确的结果。Quadrat...
On equivalence between known families of quadratic APN functions
CCZ-equivalence EA-equivalence APN
2019/7/15
We study a question whether the currently known families of quadratic APN polynomials are pairwise different up to CCZ-equivalence. We reduce the list of these families to those CCZ-inequivalent to ea...

Jacobi symbol probability distribution statistical distance
2019/6/4
We develop exact formulas for the distribution of quadratic residues and non-residues in sets of the form a+X={(a+x)modn∣x∈X}a+X={(a+x)modn∣x∈X}, where nn is a prime or the product of two primes and X...
On the boomerang uniformity of quadratic permutations over $\mathbb{F}_{2^n}$
Vectorial functions Block ciphers Boomerang uniformity
2019/3/13
At Eurocrypt'18, Cid, Huang, Peyrin, Sasaki, and Song introduced a new tool called Boomerang Connectivity Table (BCT) for measuring the resistance of a block cipher against the boomerang attack which ...
Correlation of Quadratic Boolean Functions: Cryptanalysis of All Versions of Full MORUS
Quadratic Boolean function Disjoint quadratic form Correlation attack
2019/3/1
We show that the correlation of any quadratic Boolean function can be read out from its so-called disjoint quadratic form. We further propose a polynomial-time algorithm that can transform an arbitrar...
Despite recent advances in the area of pairing-friendly Non-Interactive Zero-Knowledge proofs, there have not been many efficiency improvements in constructing arguments of satisfiability of quadratic...
Decentralized Evaluation of Quadratic Polynomials on Encrypted Data
Decentralization FHE 2-DNF
