袁源副研究员：Blowup of the entropy-bounded classical solutions to the nonisentropic compressible Navier-Stokes equations
非等熵 可压缩 纳维-斯托克斯方程 熵界经典解 爆炸
2023/4/11
This talk concerns the instantaneous blowup of entropy-bounded classical solutions to the vacuum free boundary problem or the Cauchy problem of nonisentropic compressible Navier-Stokes equations.
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Classical and adelic Eisenstein series
古典 阿德利 爱森斯坦系列 经典函数
2023/5/6
In this talk, we discuss “Hecke summation” for the classical Eisenstein series E_k in an adelic setting. The connection between classical and adelic functions is made by explicit calculations of local...
Randomly Rotate Qubits Compute and Reverse --- IT-Secure Non-Interactive Fully-Compact Homomorphic Quantum Computations over Classical Data Using Random Bases
Homomorphic encryption Quantum cryptography Information-theoretic security
2019/9/16
Homomorphic encryption (HE) schemes enable processing of encrypted data and may be used by a user to outsource storage and computations to an untrusted server. A plethora of HE schemes has been sugges...
Quantum Alice and Silent Bob: Qubit-based Quantum Key Recycling with almost no classical communication
quantum cryptography quantum key recycling
2019/8/2
We introduce a Quantum Key Recycling (QKR) protocol that needs no classical communication from Alice to Bob. Alice sends only a cipherstate, which consists of qubits that are individually measured by ...
Improved Classical Cryptanalysis of the Computational Supersingular Isogeny Problem
Post-quantum cryptography supersingular elliptic curves isogenies
2019/3/21
Two recent papers have made significant advances towards a better understanding of the concrete hardness of the computational supersingular isogeny (CSSI) problem; this problem underlies the supersing...
Classical zero-knowledge arguments for quantum computations
zero knowledge quantum computation
2019/3/1
We show that every language in BQP admits a classical-verifier, quantum-prover zero-knowledge argument system which is sound against quantum polynomial-time provers and zero-knowledge for classical (a...
Classical Proofs for the Quantum Collapsing Property of Classical Hash Functions
hash functions quantum attacks
2018/11/13
Hash functions are of fundamental importance in theoretical and in practical cryptography, and with the threat of quantum computers possibly emerging in the future, it is an urgent objective to unders...
We present an improved version of the one-way to hiding (O2H) lemma by Unruh, J ACM 2015. Our new O2H lemma gives higher flexibility (arbitrary joint distributions of oracles and inputs, multiple repr...

Quantum FHE (Almost) As Secure as Classical
fully homomorphic encryption learning with errors quantum computation
2018/4/12
Fully homomorphic encryption schemes (FHE) allow to apply arbitrary efficient computation to encrypted data without decrypting it first. In Quantum FHE (QFHE) we may want to apply an arbitrary quantum...
XHX - A Framework for Optimally Secure Tweakable Block Ciphers from Classical Block Ciphers and Universal Hashing
Provable security ideal-cipher model tweakable block cipher
2017/11/13
Tweakable block ciphers are important primitives for designing cryptographic schemes with high security. In the absence of a standardized tweakable block cipher, constructions built from classical blo...
Cryptanalysis against Symmetric-Key Schemes with Online Classical Queries and Offline Quantum Computations
post-quantum cryptography classical query model meet-in-the-middle
2017/10/9
In this paper, quantum attacks against symmetric-key schemes are presented in which adversaries only make classical queries but use quantum computers for offline computations. Our attacks are not as e...
