Why did Putin invade Ukraine? A theory of degenerate autocracy
American Journal of Political Science, EarlyView.Abstract Many dictatorships end up with a series of disastrous decisions such as Hitler's attack on the Soviet Union or Saddam Hussein's aggression against Kuwait. Even if a certain policy choice is not ultimately fatal for the regime, such as Mao's Big Leap Forward or the Pol Pot's collectivization drive, they typically involve both a miscalculation ...

Practicality and Application of the Algebraic Side-Channel Attack
, 2018 Algebraic Side-Channel Attack (ASCA) is a side-channel attack that models the cryptographic algorithm and side-channel leakage from a system as a set of equations, then solves for the secret key.

A different algebraic analysis of the ZUC stream cipher
, 2011 Existing algebraic analyses of the ZUC cipher indicate that the cipher should be secure against algebraic attacks. In this paper, we present an alternative algebraic analysis method for the ZUC stream cipher, where a combiner is used to represent the ...

State recovery attack on ACORN v3 in nonce-reuse setting
Tongxin xuebao, 2020 Based on differential-algebraic method and guess-and-determine technique,the state recovery attack of ACORN v3 was presented when one pair of key and Nonce was used to encrypt two messages.The time complexity of the attack was 2122.5c,where c was the ...

Survey on Visualization of Information Diffusion over Networks
Computer Graphics Forum, EarlyView.Abstract Information Diffusion (ID) describes how a value (e.g., a pathogen, a rumor, a packet) spreads through an underlying “medium” network of elements (e.g., a social or computer network). Understanding the information diffusion process is essential to predicting trends, controlling misinformation, and enhancing decision‐making as well as ...

Algebraic Precomputations in Differential and Integral Cryptanalysis [PDF]
, 2010 International audienceAlgebraic cryptanalysis is a general tool which permits one to assess the security of a wide range of cryptographic schemes. Algebraic techniques have been successfully applied against a number of multivariate schemes and stream ...

Attack Tree Metrics are Operad Algebras
2024 IEEE 37th Computer Security Foundations Symposium (CSF)Attack Trees (ATs) are a widely used tool for security analysis. ATs can be employed in quantitative security analysis through metrics, which assign a security value to an AT. Many different AT metrics exist, and there exist multiple general definitions that aim to study a wide variety of AT metrics at once.

Comparative Study of Algebraic Attacks
IARJSET, 2016 Cryptographic schemes have an algebraic structure and can be described as multivariate polynomial equations. Even though algebra is the default tool in the cryptanalysis of asymmetric cryptosystems, there has been recently an increase in interest in the use of algebraic cryptanalysis techniques in the analysis of symmetric cryptosystems. The basic idea

Journal of Sleep Research, EarlyView.ABSTRACT Lucid dreaming, defined as the experience of becoming aware of dreaming while dreaming, offers a unique window into a state of consciousness characterised by a blending of the sensory vividness of REM sleep with the self‐awareness of wakefulness. While past functional imaging has shed light on the neural activity supporting lucid dreaming, the
