Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rational points and homogeneous spaces over function fields of curves
曲线函数场 有理点 齐次空间
2023/4/17
In the last decade, there has been a growing interest in the study of rational points on homogeneous spaces of linear algebraic groups defined over fields having good arithmetical properties other tha...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Number of rational points of difference varieties in finite difference fields
有限差分域 差分簇 有理点数
2023/4/13
A difference field is a field with a distinguished automorphism. Automorphisms of a finite field are powers of the Frobenius map. In this talk, I will discuss how to estimate the number of rational po...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rational solutions of KP and BKP hierarchies through Toda lattice
户田晶格 KP BKP 层次结构 合理解
2023/4/27
The full Kostant-Toda lattice defined on simple Lie algebras can be viewed as finite version of KP type hierarchies. In this talk I will show you how to explicitly construct (all) rational solutions o...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：μ-basis for a tensor product rational surface with respect to one variable
张量积 有理曲面 变量 μ基
2023/4/28
The method of moving planes and moving quadrics expresses the implicit equation of a rational parametric surface as a compact determinant. Efficient computation of the moving planes and moving quadric...
Sucker punch makes you richer: The threat of rational miners
blockchain double-spending attack incentive
2019/6/26
Honest majority is a vital assumption of Bitcoin-style blockchains. However, recent 51% attacks render this assumption unrealistic in practice. In this paper, we analyse two possible 51% attacks launc...
Temporary Censorship Attacks in the Presence of Rational Miners
blockchain samrt contract bribery
2019/6/26
Smart contracts allow for exchange of coins according to program rules. While it is well known that so called bribery contracts can influence the incentive mechanism of a Nakamotostyle consensus, we p...
On Kummer Lines With Full Rational 2-torsion and Their Usage in Cryptography
Montgomery curves Edwards curves Kummer lines
2018/11/16
A paper by Karati and Sarkar at Asiacrypt'17 has pointed out the potential for Kummer lines in genus one, by observing that its SIMD-friendly arithmetic is competitive with the status quo. A more rece...
Weak Compression and (In)security of Rational Proofs of Storage
information theory proofs of storage rational security
2018/5/28
We point out an implicit unproven assumption underlying the security of rational proofs of storage that is related to a concept we call weak randomized compression.

2018/5/17
The rational polynomial coefficients (RPC) model is a generalized sensor model, which can achieve high approximation accuracy. And it is widely used in the field of photogrammetry and remote sensing. ...
But Why does it Work? A Rational Protocol Design Treatment of Bitcoin
Blockchain Protocols Rational Protocol Design Bitcoin
2018/2/8
An exciting recent line of work has focused on formally investigating the core cryptographic assumptions underlying the security of Bitcoin. In a nutshell, these works conclude that Bitcoin is secure ...
Parameterization of Edwards curves on the rational field Q with given torsion subgroups
Edwards curve twisted Edwards curve torsion subgroups
2018/1/29
This paper presents the basic concepts of the Edwards curves, twisted Edwards curves and the point addition laws on these curves. The main result is the parameterization of the Edward curve with the g...
Trust models are widely used in various computer science disciplines. The main purpose of a trust model is to continuously measure trustworthiness of a set of entities based on their behaviors. In thi...
Perfectly Secure Message Transmission Scheme against Rational Adversaries

2017/4/12
Secure Message Transmission (SMT) is a two-party cryptographic scheme by which a sender securely and reliably sends messages to a receiver using nn channels. Suppose that an adversary corrupts at most...
Rational Proofs against Rational Verifiers
rational proof delegation of computation game theory
2017/3/27
Rational proofs, introduced by Azar and Micali (STOC 2012), are a variant of interactive proofs in which the prover is rational, and may deviate from the protocol for increasing his reward. Guo et al....
