Provable Security Against a Differential Attack

open access: yesDAIMI Report Series, 1994
The purpose of this paper is to show that there exist DES-like iterated ciphers, which are provably resistant against differential attacks. The main result on the security of a DES-like cipher with independent round keys is Theorem 1, which gives an upper bound to the probability of <em>s</em>-round differentials, as defined in <em> ...

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Why Provable Security Matters? [PDF]

open access: yes, 2003
Recently, methods from provable security, that had been developped for the last twenty years within the research community, have been extensively used to support emerging standards. This in turn has led researchers as well as practitioners to raise some concerns about this methodology.

Organizational Sensemaking Theory Perspective of Developing AI‐Driven Strategies for Sustainability Initiatives

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Although artificial intelligence (AI) is increasingly being touted to assist organizations, AI integration for sustainability efforts has been limited AND sporadic and tends to follow an ad hoc strategy. The existing literature therein focuses on the technological capabilities of AI, overlooking how organizations make sense of and ...

Efficient identification protocol provably secure in standard model

open access: yesTongxin xuebao, 2009
Based on the hardness assumption of the collusion attack algorithm with k traitors (K-CAA) in a gap Diffie-Hellman (GDH) group, a new and efficient identification protocol is proposed.
