SAT-based lazy formal analysis method for security protocols
A SAT-based security protocol formalization analysis method named SAT-LMC is proposed.The method introduces optimized the initial state and transformational rules with “lazy” idea.The efficiency of detection is significantly improved.Moreover,by adding ...

Dynamic deployment of context-aware access control policies for constrained security devices [PDF]
Securing the access to a server, guaranteeing a certain level of protection over an encrypted communication channel, executing particular counter measures when attacks are detected are examples of security requirements.

This paper presents a detection algorithm for sensor attacks and a resilient state estimation scheme for a class of uniformly observable nonlinear systems. An adversary is supposed to corrupt a subset of sensors with the possibly unbounded signals, while

Using Linearizing Sets to Solve Multivariate Quadratic Equations in Algebraic Cryptanalysis
In this paper we describe a class of cryptographic guess-and-determine attacks which is based on the notion of a linearizing set. A linearizing set-based attack is applied to a system of Multivariate Quadratic equations (MQ) over $GF(2)$ field, which ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Strengthening Crypto-1 Cipher Against Algebraic Attacks
In the last few years, several studies addressed the problem of data security in Mifare Classic. One of its weaknesses is the low random number quality. This causes SAT solver attacks to have lower complexity.

SAT Attacks on ARX Ciphers with Automated Equations Generation [PDF]
We propose a novel and simple approach to algebraic attack on block ciphers with the SAT-solvers. As opposed to a standard approach, the equations for key expansion algorithms are not included in the formulas that are converted to satisfiability problem. The lack of equations leads to finding the solution much faster.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Understanding Database Reconstruction Attacks on Public Data [PDF]
In 2020 the U.S. Census Bureau will conduct the Constitutionally mandated decennial Census of Population and Housing. Because a census involves collecting large amounts of private data under the promise of confidentiality, traditionally statistics are ...
