Preparation of fluorinated epoxy-phthalonitrile resins with excellent thermal stability and low dielectric constant
curing behavior fluorinated epoxy-phthalonitrile resins low dielectric constant thermal stability
2023/11/16
Fluoropolymers find applications in heat-resistant cables, chemical-resistant linings, electronic components, cladding materials, and weather-resistant films. Therefore, it is imperative to improve th...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Liouville Properties on gradient shrinking Ricci solitons with constant scalar curvature
常标量 曲率梯度收缩 Ricci孤子 Liouville性质
2023/11/13
In this talk we show that bounded harmonic functions are constant on gradient shrinking Ricci solitons with CSC by frequency function method. As an application, we show that the space of harmonic func...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Recent Developments in Constant Mean Curvature Hypersurfaces
恒定 平均曲率 超曲面
2023/4/13
We will survey some recent existence theory of closed constant mean curvature hypersurfaces using the min-max method. We hope to discuss some old and new open problems on this topic as well.

2019/9/16
Abstract. There is a large gap between theory and practice in the complexities of sieving algorithms for solving the shortest vector problem in an arbitrary Euclidean lattice. In this paper, we work t...
How to leverage hardness of constant degree expanding polynomials over R to build iO
public-key cryptography Obfuscation
2019/9/16
In this work, we introduce and construct DD-restricted Functional Encryption (FE) for any constant D≥3D≥3, based only on the SXDH assumption over bilinear groups. This generalizes the notion of 33-res...
Formal Verification of a Constant-Time Preserving C Compiler
Compilation Formal verification Constant-time security
2019/8/19
Timing side-channels are arguably one of the main sources of vulnerabilities in cryptographic implementations. One effective mitigation against timing side-channels is to write programs that do not pe...

Lattice-Based Cryptography Cryptanalysis BLISS
2019/8/7
As one of the most efficient lattice-based signature schemes, and one of the only ones to have seen deployment beyond an academic setting (e.g., as part of the VPN software suite strongSwan), BLISS ha...
A new implementation of Falcon is presented. It solves longstanding issues in the existing reference code: the new implementation is constant-time, it does not require floating-point hardware (though ...
Privacy of Stateful RFID Systems with Constant Tag Identifiers
RFID scheme security privacy
2019/7/18
There is a major interest in designing RFID schemes based on symmetric-key cryptography and ensuring efficient tag identification. These requirements taken together often lead to a decrease in the deg...

Side-channel Attack Post-quantum Cryptography Code-based Cryptography
2019/7/15
In the last few years, post-quantum cryptography has received much attention. NIST is running a competition to select some post-quantum schemes as standard. As a consequence, implementations of post-q...
Onion Ring ORAM: Efficient Constant Bandwidth Oblivious RAM from (Leveled) TFHE
Homomorphic Encryption Oblivious RAM
2019/6/24
Oblivious RAM (ORAM) is a cryptographic primitive that allows a client to hide access pattern to its data encrypted and stored at a remote server. Traditionally, ORAM algorithms assume the server acts...
