Passive–Only Key Recovery Attacks on RC4 [PDF]

, 2007
We present several weaknesses in the key scheduling algorithm of RC4 when the secret key contains an initialization vector - a cryptographic scheme typically used by the WEP and WPA protocols to protect IEEE 802.11 wireless communications. First, we show how the previously discovered key recovery attacks can be improved by reducing the dependency ...

Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

THEORETICALLY UNBREAKABLE CIPHERS AS THEY SHOULD BE UNDERSTOOD

Современные информационные технологии и IT-образование, 2018
Perfectly-secret ciphers according to the Claude Shannon's theory, which are considered as unbreakable, and more specifically random keystream ciphers, are discussed. An analysis of the sources mentioned in the reference list showed that all of them come

Clinical Spectrum and Outcomes of SOX1 Antibody‐Associated Paraneoplastic Neurological Syndromes: A Chinese Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background SOX1 antibody‐positive paraneoplastic neurological syndromes (PNS) exhibit significant population‐specific clinical heterogeneity. While Western cohorts predominantly manifest Lambert‐Eaton myasthenic syndrome (65%–80%), comprehensive clinical characterization and treatment response data in Asian populations remain critically ...

Quantum key-recovery attacks on FBC algorithm

Quantum Information Processing
With the advancement of quantum computing, symmetric cryptography faces new challenges from quantum attacks. These attacks are typically classified into two models: Q1 (classical queries) and Q2 (quantum superposition queries). In this context, we present a comprehensive security analysis of the FBC algorithm considering quantum adversaries with ...

A Simple Key-Recovery Attack on McOE-X [PDF]

, 2012
In this paper, we present a key-recovery attack on the online authenticated encryption scheme McOE-X proposed by Fleischmann et al. at FSE 2012. The attack is based on the observation that in McOE-X the key is changed for every block of message that is encrypted in a deterministic way.

Improved Meet-in-the-Middle Attacks on Generic Feistel Constructions

IEEE Access, 2019
In this paper, we present improved meet-in-the-middle key-recovery attacks on six-round and seven-round Feistel constructions separately. The attacks are based on Guo et al.'s work which appends one round to the five-round distinguisher to attack the six-

Key recovery attack on Circulant UOV/Rainbow

JSIAM Letters, 2019
Summary: UOV and Rainbow are multivariate signature schemes, which are known to be efficient and secure enough against known attacks under suitable parameter selections, and have been expected to be post-quantum cryptography. Recently, new variants of UOV and Rainbow, called Circulant UOV and Circulant Rainbow respectively, were proposed by \textit{Z ...
