Imagine using an online banking app to deposit money into your account. Like all information sent over the internet, those communications could be corrupted by noise that inserts errors into the data.
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Many-body localization and quantum many-body scars: The strong and weak form of ergodicity breaking
多体定位 量子多体疤痕 遍历性断裂 强弱形式
2023/4/23
The fate of an isolated quantum many-body system has attracted much attention in the past decade. One of the most important issues is whether such a system can reach thermalization under its own dynam...
As machine-learning models become larger and more complex, they require faster and more energy-efficient hardware to perform computations. Conventional digital computers are struggling to keep up.
Engineers use artificial intelligence to capture the complexity of breaking waves（图）
人工智能 破浪 复杂性 模型预测 海洋气候模拟

Breaking and Fixing Anonymous Credentials for the Cloud (Full Version)
Attribute-based credentials Privacy-preserving authentication Strong authentication
2019/9/23
In an attribute-based credential (ABC) system, users obtain a digital certificate on their personal attributes, and can later prove possession of such a certificate in an unlinkable way, thereby selec...
Breaking the Bluetooth Pairing – The Fixed Coordinate Invalid Curve Attack
Bluetooth elliptic curve cryptosystem Diffie-Hellman
2019/9/19
Bluetooth is a widely deployed standard for wireless communications between mobile devices. It uses authenticated Elliptic Curve Diffie-Hellman for its key exchange. In this paper we show that the aut...
Breaking the Lightweight Secure PUF: Understanding the Relation of Input Transformations and Machine Learning Resistance
Physically Unclonable Function Machine Learning Modelling Attack
2019/7/15
Physical Unclonable Functions (PUFs) and, in particular, XOR Arbiter PUFs have gained much research interest as an authentication mechanism for embedded systems. One of the biggest problems of (strong...
Breaking Tweakable Enciphering Schemes using Simon's Algorithm
TES Simon's algorithm Quantum period finding algorithm
2019/6/19
The threat of the possible advent of quantum computers has motivated the cryptographic community to search for quantum safe solutions. There have been some works in past few years showing the vulnerab...
Assuring security of the Internet of Things (IoT) is much more challenging than assuring security of centralized environments, like the cloud. A reason for this is that IoT devices are often deployed ...
Finding a Nash Equilibrium Is No Easier Than Breaking Fiat-Shamir
TFNP PPAD Nash Equilibrium
2019/5/23
The Fiat-Shamir heuristic transforms a public-coin interactive proof into a non-interactive argument, by replacing the verifier with a cryptographic hash function that is applied to the protocol’s tra...
One Fault is All it Needs: Breaking Higher-Order Masking with Persistent Fault Analysis
fault attacks masking persistent
2019/1/9
Persistent fault analysis (PFA) was proposed at CHES 2018 as a novel fault analysis technique. It was shown to completely defeat standard redundancy based countermeasure against fault analysis. In thi...
Breaking the Binding: Attacks on the Merkle Approach to Prove Liabilities and its Applications
proof of liabilities Maxwell protocol summation Merkle tree
2018/11/30
Proofs of liabilities are used for applications, function like banks or Bitcoin exchanges, to prove the sums of money in their dataset that they should owe. The Maxwell protocol, a cryptographic proof...
OCB2 is a widely standardized mode of operation of a blockcipher that aims at providing authenticated encryption. A recent report by Inoue and Minematsu (IACR EPRINT report 2018/1040) indicates that O...
