Improved Distinguishing Attacks on HC-256 [PDF]

, 2009
The software-efficient stream cipher HC-256 was proposed by Wu at FSE 2004. Due to its impressive performance, the cipher was also a well-received entrant to the ECRYPT eSTREAM competition. The closely related stream cipher HC-128, also designed by Wu, went on to find a place in the final portfolio of the eSTREAM contest.

Cryptanalysis of the Hillery-Buzek-Berthiaume quantum secret-sharing protocol

, 2008
The participant attack is the most serious threat for quantum secret-sharing protocols. We present a method to analyze the security of quantum secret-sharing protocols against this kind of attack taking the scheme of Hillery, Buzek, and Berthiaume (HBB) [

Cryptanalysis on the HHSS Obfuscation Arising From Absence of Safeguards

IEEE Access, 2018
Indistinguishability Obfuscation (iO) is a hopeful tool which obfuscates a program with the least-possible leakage, and produces various applications including functional encryption and deniable encryption. Recently, Halevi et. al.

Machine Learning Attacks‐Resistant Security by Mixed‐Assembled Layers‐Inserted Graphene Physically Unclonable Function

Advanced Science, 2023
Mixed layers of octadecyltrichlorosilane (ODTS) and 1H,1H,2H,2H‐perfluorooctyltriethoxysilane (FOTS) on an active layer of graphene are used to induce a disordered doping state and form a robust defense system against machine‐learning attacks (ML attacks)

Synesthesia: Detecting Screen Content via Remote Acoustic Side Channels

, 2019
We show that subtle acoustic noises emanating from within computer screens can be used to detect the content displayed on the screens. This sound can be picked up by ordinary microphones built into webcams or screens, and is inadvertently transmitted to ...

Why Quantum Bit Commitment And Ideal Quantum Coin Tossing Are Impossible [PDF]

, 1997
There had been well known claims of unconditionally secure quantum protocols for bit commitment. However, we, and independently Mayers, showed that all proposed quantum bit commitment schemes are, in principle, insecure because the sender, Alice, can ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
