From an information security perspective, protecting sensitive data requires utilizing algorithms which resist theoretical attacks. However, treating an algorithm in a purely mathematical fashion or in other words abstracting away from its physical (hardware or software) implementation opens the door to various real-world security threats. In the modern age of electronics, cryptanalysis attempts to reveal secret information based on cryptosystem physical properties, rather than exploiting the theoretical weaknesses in the implemented cryptographic algorithm. The correlation power attack (CPA) is a Side-Channel Analysis attack used to reveal sensitive information based on the power leakages of a device. In this paper, we present a power Hacking technique to demonstrate how a power analysis can be exploited to reveal the secret information in AES crypto-core. In the proposed case study, we explain the main techniques that can break the security of the considered crypto-core by using CPA attack. Using two cryptographic devices, FPGA and 8051 microcontrollers, the experimental attack procedure shows that the AES hardware implementation has better resistance against power attack compared to the software one. On the other hand, we remark that the efficiency of CPA attack depends statistically on the implementation and the power model used for the power prediction.

The Belgian textile wallcovering has the following background. The unique oceanic climate is optimized for flax. Beginning in the thirteenth century, British wool was produced for export to Britain or neighboring countries. Since the 15th century, Flemish paintings were influenced by color implementations, and these colors have influenced the developments of tapestry and art. Since that time, tapestry and paintings combined with paper technologies and Oriental civilizations, such as silk, that had been developed through trade ports, have been transformed into the form of current wallcoverings. Belgium produces the highest quality textile wallcovering using natural materials i.e., a combination of irregular and modern materials, and the implementation of different colors. The Belgian textile wallcovering is also a good representation of nature at the Heimtextil 2018, It provides a wide range of colors while retaining the best styles for wallcoverings in Belgium. The characteristics of Belgian wall coverings are: First, the high proportion of achromatic colors, especially the white ones, are analyzed for current trends. Second, it expresses the characteristics of materials by using only one material. This not only shows a high level of understanding of natural materials, but also shows a high level of development in terms of processing technology. Thirdly, linen was made into a formative expression using wrinkle processing and by printing geometric patterns, the rough texture of natural materials was expressed in harmony with modern patterns.

The Oroqen (鄂伦春) traditional costume refers to what the nomadic Oroqen people used to wear before they settled into fixed communities. With very limited contact with the outside world and with limited resources, the clothing material was virtually entirely animal hide. With settlement, especially after 1996, animal hide clothing has declined among the Oroqen. As an important part of Oroqen tradition and culture, the Oroqen people keep endevoring to promote costume design through competition and exhibitions. Therefore, this paper seeks to present an insightful understanding of Oroqen culture and the formative features of their general clothing. We explored the formative features of Oroqen animal hide clothing based on an analysis of actual artifacts and literature. As a result, the characteristics of Oroqen hide clothing were found in five types - coats, trousers, hats, shoes, gloves. For the decoration, embroidery and applique were their way of decoration, and Mother Nature was their source of pattern design.

This paper provides a review of wearable textile strain sensors that can measure the deformation of the body surface according to the movements of the wearer. In previous studies, the requirements of textile strain sensors, materials and fabrication methods, as well as the principle of the strain sensing according to sensor structures were understood; furthermore, the factors that affect the sensing performance were critically reviewed and application studies were examined. Textile strain sensors should be able to show piezoresistive effects with consistent resistance-extension in response to the extensional deformations that are repeated when they are worn. Textile strain sensors with piezoresistivity are typically made using conductive yarn knit structures or carbon-based fillers or conducting polymer filler composite materials. For the accuracy and reliability of textile strain sensors, fabrication technologies that would minimize deformation hysteresis should be developed and processes to complement and analyze sensing results based on accurate understanding of the sensors' resistance-strain behavior are necessary. Since light-weighted, flexible, and highly elastic textile strain sensors can be worn by users without any inconvenience so that to enable the users to continuously collect data related to body movements, textile strain sensors are expected to become the core of human interface technologies with a wide range of applications in diverse areas.

Industrial innovation in Britain, during the eighteenth and nineteenth centuries, stimulated the introduction of the factory system and the migration of people from rural agricultural communities to urban industrial societies. The factory system brought elevated levels of economic growth to the purveyors of capitalism, but forced people to migrate into cities where working conditions in factories were, in general, harsh and brutal, and living conditions were cramped, overcrowded and unsanitary. Industrial developments, known collectively as the 'Industrial Revolution', were driven initially by the harnessing of water and steam power, and the widespread construction of rail, shipping and road networks. Parallel with these changes, came the development of purchasing 'middle class', consumers. Various technological ripples (or waves of innovative activity) continued (worldwide) up to the early-twenty-first century. Of recent note are innovations in digital technology, with associated developments, for example, in artificial intelligence, robotics, 3-D printing, materials technology, computing, energy storage, nano-technology, data storage, biotechnology, 'smart textiles' and the introduction of what has become known as 'e-commerce'. This paper identifies the more important early technological innovations, their influence on textile manufacture, distribution and consumption, and the changed role of the designer and craftsperson over the course of these technological ripples. The implications of non-ethical production, globalisation and so-called 'fast fashion' and non-sustainability of manufacture are examined, and the potential benefits and opportunities offered by new and developing forms of social media are considered. The message is that hand-crafted products are ethical, sustainable and durable.
