Low-Latency Masked Gadgets Robust against Physical Defaults with Application to Ascon
Transactions on Cryptographic Hardware and Embedded SystemsLow-latency masked hardware implementations are known to be a difficult challenge. On the one hand, the propagation of glitches can falsify their independence assumption (that is required for security) and can only be stopped by registers.

Towards Globally Optimized Masking: From Low Randomness to Low Noise Rate
Transactions on Cryptographic Hardware and Embedded Systems, 2019 We improve the state-of-the-art masking schemes in two important directions. First, we propose a new masked multiplication algorithm that satisfies a recently introduced notion called Probe-Isolating Non-Interference (PINI).

Symbols of Climate Action: Audit Labor and the Production of Carbon Credits
Economic Anthropology, EarlyView.ABSTRACT Voluntary carbon markets (VCMs) are promoted as tools for financing climate mitigation, yet their effectiveness and credibility remain contested. This article examines how carbon credits are produced and destabilized as symbols of climate action, emphasizing the forms of ecological and audit labor that sustain their legitimacy.

Unnatural Causes: Cryptocurrencies, Carbon Credits, and the rise of Neoliberalism from Below
Economic Anthropology, EarlyView.ABSTRACT Klima is a carbon‐backed cryptocurrency running as a decentralized autonomous organization (DAO). In 2021, it had accumulated 9 million metric tons of digital carbon credits and reached a market value of more than US$1 billion. In 2023, its treasury stored twice as many carbon credits, but its spot price was a tiny fraction compared to 2021 ...
