Provably Secure Authenticated Encryption
, 2018 Authenticated Encryption (AE) is a symmetric key cryptographic primitive that ensures confidentiality and authenticity of processed messages at the same time. The research of AE as a primitive in its own right started in 2000. The security goals of AE were captured in formal definitions in the tradition in the tradition of provable security (such as ...

Another Look at Provable Security [PDF]
, 2012 Many cryptographers believe that the only way to have confidence in the security of a cryptographic protocol is to have a mathematically rigorous proof that the protocol meets its stated goals under certain assumptions. However, it is often difficult to assess what such proofs really mean in practice especially if the proof is non-tight, the underlying

Business Strategy and the Environment, EarlyView.ABSTRACT Why do firms facing similar sustainability pressures differ substantially in circular economy implementation? Existing research provides limited insight into how institutional pressures are internally interpreted and translated into organizational action. Drawing on institutional theory, paradox theory, and the dynamic capabilities perspective,

The Circular Economy—A New Resilience Paradigm?
Business Strategy and the Environment, EarlyView.ABSTRACT The circular economy (CE) has traditionally been positioned as a central instrument of the sustainability paradigm. Yet escalating geopolitical volatility and supply chain fragility have elevated resilience to a parallel strategic imperative, and the conceptual integration of CE and resilience remains underexplored.

Who Qualifies to Assure? The Professional and Managerial Capture of Sustainability Assurance
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how the qualification of assurors in sustainability and environmental reporting assurance (SERA) is constructed and why it remains fiercely contested. Drawing on actor–network theory (ANT) and qualitative evidence from regulators, NGOs, assurors and reporting companies in India, we conceptualise ‘qualification’ as a ...

White-Box Tweakable Block Cipher and Hardware-Binding Scheme Under Tweak-Unique Mode
InformationWhite-box cryptography protects secret keys in untrusted execution environments but remains vulnerable to code lifting attacks. Hardware-binding offers a practical countermeasure by coupling cryptographic implementations with specific devices, yet a ...

On Provable Security for Complex Systems
, 2016 We investigate the contribution of cryptographic proofs of security to a systematic security engineering process. To this end we study how to model and prove security for concrete applications in three practical domains: computer networks, data outsourcing, and electronic voting.

Short Signatures, Provable Security, Generic Attacks and Computational Security of Multivariate Polynomial Schemes such as HFE, Quartz and Sflash [PDF]
, 2004 The object of this paper is the concrete security of recent multivariate signature schemes. A major challenge is to reconcile some "tricky" ad-hoc constructions that allow to make short signatures, with regular provable security.
