Purpose: This paper aims to propose a structured threat information expression (STIX)-based data representation for privacy-preserving data analysis to report format and semantics of specific data types and to represent sticky policies in the format of embedded human-readable data sharing...

Analyzing the decay properties of the Green's function for a particular Schrödinger operator on L2(R) we show that in a suitable sense there is no diffusion when the energy is near the bottom of the spectrum.

Tabular and graphical representations are used to communicate security risk assessments for IT systems. However, there is no consensus on which type of representation better supports the comprehension of risks (such as the relationships between threats, vulnerabilities and security controls)....

Determining the transition matrix of a discrete Markov process from sequential forecasts of smoothed density functions is an important element of many problems in decision theory and economics. Recent theoretical results have demonstrated that the Perron-Frobenius eigenfunction of a Markov risk...

This study addresses various issues in the study of interdependent cyber security, and sheds light on the economic and policy implications of increasing security interdependence. We investigate the impact of a policy arrangement affecting security interdependence on agents' regulated and...

Blockchains and Byzantine Fault Tolerance form the basis of decentralized currencies and ledgers such as Bitcoin, Ripple, ZeroCash, and Ethereum. A large slate of literature has focused on the currency aspects (e.g. anonymity, independence from central banks, etc.). We argue that, as-far-as...
