Encasing Block Ciphers to Foil Key Recovery Attempts via Side Channel

Providing efficient protection against energy consumption based side channel attacks (SCAs) for block ciphers is a relevant topic for the research community, as current overheads are in the 100× range. Unprofiled SCAs exploit information leakage from the outmost rounds of a cipher; we propose a solution encasing it between keyed transformations amenable to an efficient SCA protection. Our solution can be employed as a drop in replacement for an unprotected implementation, or be retrofit to an existing one, while retaining communication capabilities with legacy insecure endpoints. Experiments on a Cortex-M4 μC, show performance improvements in the range of 60×, compared with available solutions

Side-channel security of superscalar CPUs: Evaluating the Impact of Micro-architectural Features

Side-channel attacks are performed on increasingly complex targets, starting to threaten superscalar CPUs supporting a complete operating system. The difficulty of both assessing the vulnerability of a device to them, and validating the effectiveness of countermeasures is increasing as a consequence. In this work we prove that assessing the side-channel vulnerability of a software implementation running on a CPU should take into account the microarchitectural features of the CPU itself. We characterize the impact of microarchitectural features and prove the effectiveness of such an approach attacking a dual-core superscalar CPU

New York City Street Theater: Gender, Performance, and the Urban from Plessy to Brown

This dissertation investigates the ordinary, public performances of fictional female characters in novels set on the streets of Manhattan during the years of legal segregation in the United States. I examine a range of actions from bragging to racial passing, and I argue these ordinary performances are central to our ability to interpret race, gender, and class relations. I detect race, class, and gender-based impulses to segregate and exclude others that overlap with the motives guiding the national, legal edict to segregate people by race. These guiding inclinations, legible through the history of Manhattan\u27s grid, zoning laws, and the city officials\u27 treatment of the poor, for example, are also the tendencies directing fictional characters in the texts I explore. By considering fictional performances against the backdrop of actual history, I ask how and why both real and imagined people aim to squelch singularity or uniqueness in themselves or others. I argue that while some performances deaden the fictional actors, others suggest there are alternative modes of acting through which one might be empowered by abjection despite it

North-east childhoods : regional identity in children's novels of the North East of England

This thesis explores how children's writers have participated in the process of representing and constructing the identity of the North East of England. It argues that there exists a dominant North-East aesthetic which has become deeply embedded within British children's fiction, and that several of its key motifs (labour, industry and decline; traditional gender roles and landscape) recur frequently within portrayals of the region in writing for the young. This aesthetic contributes to a perception of the region as both marginal and marginalised, and masks realities about the North East. Following an overview of children's literature set in the region, from the late nineteenth to the early twenty-first centuries, the focus moves to the work of Robert Westall, a major children's writer who was born in Tyneside and set much of h'is fiction within the region. The Westall chapters draw on the Robert Westall Collection at Seven Stories: The Centre for Children's Books. The more recent work of North-East writer David Almond is considered in the closing chapters which also draw on unpublished material and interviews for this thesis. Key works discussed: Robert Westall, Falling into Glory, Fathom Five, The Kingdom by the Sea, The Machine Gunners, A Time of Fire, The Wind Eye, The Watch House; David Almond, Clay, The Fire-Eaters, Heaven Eyes, Kit's Wilderness, My Dad's a Birdman, The Savage, Secret Heart, Skellig.EThOS - Electronic Theses Online ServiceArts and Humanities Research Council : Newcastle University : Seven Stories: the Centre for Children's BooksGBUnited Kingdo

Into the past : nationalism and heritage in the neoliberal age

This thesis examines the ideological nexus of nationalism and heritage under the social conditions of neoliberalism. The investigation aims to demonstrate how neoliberal economics stimulate the irrationalism manifest in nationalist idealisation of the past. The institutionalisation of national heritage was originally a rational function of the modern state, symbolic of its political and cultural authority. With neoliberal erosion of the productive economy and public institutions, heritage and nostalgia proliferate today in all areas of social life. It is argued that this represents a social pathology linked to the neoliberal state’s inability to construct a future-orientated national project. These conditions enhance the appeal of irrational nationalist and regionalist ideologies idealising the past as a source of cultural purity. Unable to achieve social cohesion, the neoliberal state promotes multiculturalism, encouraging minorities to embrace essentialist identity politics that parallel the nativism of right-wing nationalists and regionalists. This phenomenon is contextualised within the general crisis of progressive modernisation in Western societies that has accompanied neoliberalisation and globalisation. A new theory of activist heritage is advanced to describe autonomous, politicised heritage that appropriates forms and practices from the state heritage sector. Using this concept, the politics of irrational nationalism and regionalism are explored through fieldwork, including participant observation, interviews and photography. The interaction of state and activist heritage is considered at the Wewelsburg 1933-1945 Memorial Museum in Germany wherein neofascists have re-signified Nazi material culture, reactivating it within contemporary political narratives. The activist heritage of Israeli Zionism, Irish Republicanism and Ulster Loyalism is analysed through studies of museums, heritage centres, archaeological sites, exhibitions, monuments and historical re-enactments. These illustrate how activist heritage represents a political strategy within irrational ideologies that interpret the past as the ethical model for the future. This work contends that irrational nationalism fundamentally challenges the Enlightenment’s assertion of reason over faith, and culture over nature, by superimposing pre-modern ideas upon the structure of modernity. An ideological product of the Enlightenment, the nation state remains the only political unit within which a rational command of time and space is possible, and thus the only viable basis for progressive modernity

The gilded Buddha - The traditional art of the Newar metal casters in Nepal

This book celebrates in words and images the traditional metal crafts practised for over a thousand years by the creators of religious Buddhist statues in Nepal. The skills of these artisans are nurtured with deep respect for tradition, regarding religion, iconography and technology. Wax modellers, mould makers, casters, fire-gilders and chasers are among the specialists of the Newar ethnic group, whose work is characterised to this day by a melding of age-old technology, great skill, religious observance and contemplation. There are numerous books and exhibition catalogues dedicated to Buddhist art and iconography but little was available about the craft of the artists who turn the religious imagery into metal casts. This book fills this gap, with a thoroughly documented and historical account of the development of this “archaic” technology. The well-informed text and comprehensive photographic coverage constitute the only up-to-date account and full documentation of an art that is 1300 years old but dying out: the “ritual” production of Buddhist statues in the lost wax casting technique. The author, Dr. Alex Furger, is an archaeologist who has studied ancient metallurgy and metalworking techniques over the past four decades. He spent twenty-five years at the head of the Roman site of Augusta Raurica and lives in Basel (Switzerland). He is the author of over 130 articles in scientific journals and twelve books in the field of culture history. The fieldwork for this book led him repeatedly to Nepal, where he met and interviewed dozens of craftsmen in their workshops. This book is addressed to readers interested in culture history, travellers to Asia, collectors of statues of Buddha, (avocational) metalworkers, historians of technology, Buddhists, ethnologists, archaeologists, art historians, scholars of Asia and to libraries and museums

Maritime expressions:a corpus based exploration of maritime metaphors

This study uses a purpose-built corpus to explore the linguistic legacy of Britain’s maritime history found in the form of hundreds of specialised ‘Maritime Expressions’ (MEs), such as TAKEN ABACK, ANCHOR and ALOOF, that permeate modern English. Selecting just those expressions commencing with ’A’, it analyses 61 MEs in detail and describes the processes by which these technical expressions, from a highly specialised occupational discourse community, have made their way into modern English. The Maritime Text Corpus (MTC) comprises 8.8 million words, encompassing a range of text types and registers, selected to provide a cross-section of ‘maritime’ writing. It is analysed using WordSmith analytical software (Scott, 2010), with the 100 million-word British National Corpus (BNC) as a reference corpus. Using the MTC, a list of keywords of specific salience within the maritime discourse has been compiled and, using frequency data, concordances and collocations, these MEs are described in detail and their use and form in the MTC and the BNC is compared. The study examines the transformation from ME to figurative use in the general discourse, in terms of form and metaphoricity. MEs are classified according to their metaphorical strength and their transference from maritime usage into new registers and domains such as those of business, politics, sports and reportage etc. A revised model of metaphoricity is developed and a new category of figurative expression, the ‘resonator’, is proposed. Additionally, developing the work of Lakov and Johnson, Kovesces and others on Conceptual Metaphor Theory (CMT), a number of Maritime Conceptual Metaphors are identified and their cultural significance is discussed
