The constant rank theorem was initially developed by Caffarelli-Friedman in 1985 in two-dimensions for convex solutions of semilinear equations. Later, Korevaar-Lewis extended the result to higher dim...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Dynamic copula-based nonparametric estimation of rank-tracking probabilities with longitudinal data
动态copula 纵向数据秩 跟踪概率 非参数估计
2023/5/10
The rank-tracking probability (RTP) is a useful statistical index for measuring the ``tracking ability'' of longitudinal disease risk factors in biomedical studies. A flexible nonparametric method for...

Predicate Encryption Bilinear Maps Probabilistic Rank
2019/9/19
In predicate encryption for a function ff, an authority can create ciphertexts and secret keys which are associated with `attributes'. A user with decryption key KyKy corresponding to attribute yy can...
探讨RANKL/RANK通路对神经母细胞瘤（neuroblastoma，NB）SH-SY5Y细胞系细胞侵袭和转移的作用机制。方法：通过pcDNA3.1+-RANKL和siRNA-RANKL转染NB SH-SY5Y细胞系过表达或沉默外源基因RANKL；细胞增殖实验(cell counting kit-8，CCK-8)检测外源基因RANKL转染NB SH-SY5Y细胞系对细胞增殖的影响；划痕试验检测外...
We describe a variation of the Schnorr-Lyubashevsky approach to devising signature schemes that is adapted to rank based cryptography. This new approach enables us to obtain a randomization of the sig...
A set S⊆Fn2S⊆F2n is called degree-dd zero-sum if the sum ∑s∈Sf(s)∑s∈Sf(s) vanishes for all nn-bit Boolean functions of algebraic degree at most dd. Those sets correspond to the supports of...

code-based cryptography rank-metric codes interleaving
2018/12/19
A repair of the Faure-Loidreau (FL) public-key code-based cryptosystem is proposed.The FL cryptosystem is based on the hardness of list decoding Gabidulin codes which are special rank-metric codes. We...
Poly-Logarithmic Side Channel Rank Estimation via Exponential Sampling
Side Channel Rank Estimation Key Enumeration
2018/11/13
Rank estimation is an important tool for a side-channel evaluations laboratories. It allows estimating the remaining security after an attack has been performed, quantified as the time complexity and ...
DRANKULA: a McEliece-like rank metric based cryptosystem implementation
Code-based cryptography Public key cryptography Cryptosystem
2018/8/28
We present and analyze the performance of DRANKULA, a McEliece-like cryptosystem implementation using \textit{rank metric} instead of Hamming distance. Namely, we use the scheme proposed by Loidreau i...
