Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Estimating Factor-Based Spot Volatility Matrices with Noisy and Asynchronous High-Frequency Data
噪声 异步高频 数据估算 因子 现货波动率 矩阵
2023/5/4
With noisy and asynchronous high-frequency data collected for an ultra-large number of assets, we estimate high-dimensional spot volatility matrices satisfying a low-rank plus sparse structure. A loca...
On the Commitment Capacity of Unfair Noisy Channels
Commitment capacity unconditionally secure cryptography unfair noisy channels
2019/5/28
Noisy channels are a valuable resource from a cryptographic point of view. They can be used for exchanging secret-keys as well as realizing other cryptographic primitives such as commitment and oblivi...
Non-Malleable Secret Sharing in the Computational Setting: Adaptive Tampering, Noisy-Leakage Resilience, and Improved Rate
secret sharing non-malleability leakage resilience computational security
2019/2/27
We revisit the concept of *non-malleable* secret sharing (Goyal and Kumar, STOC 2018) in the computational setting. In particular, under the assumption of one-to-one one-way functions, we exhibit a *c...
Key Encapsulation from Noisy Key Agreement in the Quantum Random Oracle Model
key exchange key encapsulation mechanism post-quantum cryptography
2018/11/13
A multitude of post-quantum key encapsulation mechanisms (KEMs) and public key encryption (PKE) schemes implicitly rely on a protocol by which Alice and Bob exchange public messages and converge on se...

How to Securely Compute with Noisy Leakage in Quasilinear Complexity
Side-Channel Attacks Noisy Leakage Model Provable Security
2017/9/25
Since their introduction in the late 90's, side-channel attacks have been considered as a major threat against cryptographic implementations. This threat has raised the need for formal leakage models ...
Approximate Polynomial Common Divisor Problem Relates to Noisy Multipolynomial Reconstruction
Approximate polynomial common divisor problem noisy multipolynomial reconstruction polynomial lattice
2017/4/17
In this paper, we investigate the hardness of the approximate polynomial common divisor problem, which is regarded as a polynomial analogy of the approximate integer common divisor problem. In order t...
Passwords bootstrap symmetric and asymmetric cryptography, tying keys to an individual user. Biometrics are intended to strengthen this tie. Unfortunately, biometrics exhibit noise between repeated re...
