Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Integrability and constructions of the peakon systems
peakon系统 可积性 构造 Camassa-Holm方程
2023/11/13
Since the discovery of Camassa-Holm equation, because of the special properties that peakon gets, it has received considerable attention in modern Mathematics and Physics. Many new integrable dynamic ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On constructions of Lax representations: some examples
松弛表示 构造 非线性数学物理方程 KdV方程
2023/4/24
著名数学家Peter Lax 在1968年将重要的非线性数学物理方程---KdV方程表示为一个算子方程， 即给出了KdV方程的Lax表示或Lax对。Lax对在孤立子理论的发展中扮演者重要角色，可以看成是研究可积系统的出发点。但如何构造一个给定非线性系统的Lax表示却是非常困难的问题。本报告在概述Lax表示历史的基础上，以Boris Kupershmidt提出的两个非线性发展型方程为具体例子，介绍L...
Subversion-Resistant Commitment Schemes: Definitions and Constructions
Commitment schemes subversion security common reference string model
2019/9/23
A commitment scheme allows a committer to create a commitment to a secret value, and later may open and reveal the secret value in a verifiable manner. In the common reference string model, commitment...
Inclusory constructions in the Māori languages of Aotearoa and the Southern Cook Islands
Cook Islands Māori coordination inclusory constructions Māori Oceanic Linguistics
2019/10/10
This paper discusses Lichtenberk’s notion of inclusory constructions as manifested in two closely related East Polynesian languages of the realm of New Zealand: New Zealand Māori and Cook Islands Māor...
In order to study the resistance of a block cipher against boomerang attacks, a tool called the Boomerang Connectivity Table (BCT) for S-boxes was recently introduced. Very little is known today about...

2019/8/27
Over the last few years there has been a surge of new cryptographic results, including laconic oblivious transfer, (anonymous/ hierarchical) identity-based encryption, trapdoor functions, chosen-ciphe...
Code Constructions for Physical Unclonable Functions and Biometric Secrecy Systems
Information theoretic security key agreement physical unclonable functions

The two-terminal key agreement problem with biometric or physical identifiers is considered. Two linear code constructions based on Wyner-Ziv coding are developed. The first construction uses random l...
Estimating Gaps in Martingales and Applications to Coin-Tossing: Constructions and Hardness
information theory foundations distributed cryptography
2019/7/8
Consider the representative task of designing a distributed coin-tossing protocol for nn processors such that the probability of heads is X0∈[0,1]X0∈[0,1], and an adversary can reset one processor to ...
Security-Efficiency Tradeoffs in Searchable Encryption -- Lower Bounds and Optimal Constructions
searchable encryption lower bound
2019/6/13
Besides their security, the efficiency of searchable encryption schemes is a major criteria when it comes to their adoption: in order to replace an unencrypted database by a more secure construction, ...
Exploring Constructions of Compact NIZKs from Various Assumptions
non-interactive zero-knowledge pairing homomorphic equivocal commitment
2019/6/4
A non-interactive zero-knowledge (NIZK) protocol allows a prover to non-interactively convince a verifier of the truth of the statement without leaking any other information. In this study, we explore...
