Revizor: Testing Black-Box CPUs Against Speculation Contracts [PDF]
IEEE Micro, 2021 Speculative execution attacks such as Spectre and Meltdown exploit microarchitectural optimizations to leak information across security domains. These vulnerabilities often stay undetected for years because we lack the tools for systematic analysis of ...

The Sixth Mass Extinction: fact, fiction or speculation?
Biological Reviews of The Cambridge Philosophical Society, 2022 There have been five Mass Extinction events in the history of Earth's biodiversity, all caused by dramatic but natural phenomena. It has been claimed that the Sixth Mass Extinction may be underway, this time caused entirely by humans.

Hardware-Software Contracts for Secure Speculation [PDF]
IEEE Symposium on Security and Privacy, 2020 Since the discovery of Spectre, a large number of hardware mechanisms for secure speculation has been proposed. Intuitively, more defensive mechanisms are less efficient but can securely execute a larger class of programs, while more permissive ...

Distrust or Speculation? The Socioeconomic Drivers of U.S. Cryptocurrency Investments
Social Science Research Network, 2022 Employing representative data from the U.S. Survey of Consumer Payment Choice, we disprove the hypothesis that cryptocurrency investors are motivated by distrust in fiat currencies or regulated finance.

Speculation: a political economy of technologies of imagination
Economy and Society, 2020 This introduction explores how to build a critical analysis of post-crisis capitalism by moving beyond Marx, Foucault and Callon's approaches. This is crucially important because powerful technocratic institutions and the discipline of economics are ...

SafeSpec: Banishing the Spectre of a Meltdown with Leakage-Free Speculation [PDF]
Design Automation Conference, 2018 Speculative attacks, such as Spectre and Meltdown, target speculative execution to access privileged data and leak it through a side-channel. In this paper, we introduce (SafeSpec), a new model for supporting speculation in a way that is immune to the ...

Speculative Authorization [PDF]
IEEE Transactions on Parallel and Distributed Systems, 2013 As enterprises aim towards achieving zero latency for their systems, latency introduced by authorization process can act as an obstacle towards achieving their goal. We present \emph{\underline{Sp}eculative \underline{A}uthorizatio\underline{n}} (SPAN), a prediction technique to address the problem of latency in enterprise authorization systems.

SpecMCTS: Accelerating Monte Carlo Tree Search Using Speculative Tree Traversal
IEEE Access, 2021 Monte Carlo Tree Search (MCTS) algorithms show outstanding strengths in decision-making problems such as the game of Go. However, MCTS requires significant computing loads to evaluate many nodes in the decision tree to make a good decision. Parallelizing
