We present, for the first time, a general strategy for designing ARX symmetric-key primitives with provable resistance against single-trail differential and linear cryptanalysis. The latter has been a long standing open problem in the area of ARX design. The Wide-Trail design Strategy (WTS), that is at the basis of many S-box based ciphers, including the AES, is not suitable for ARX designs due to the lack of S-boxes in the latter. In this paper we address the mentioned limitation by proposing the Long-Trail design Strategy (LTS) -- a dual of the WTS that is applicable (but not limited) to ARX constructions. In contrast to the WTS, that prescribes the use of small and efficient S-boxes at the expense of heavy linear layers with strong mixing properties, the LTS advocates the use of large (ARX-based) S-Boxes together with sparse linear layers. With the help of the so-called long-trail argument, a designer can bound the maximum differential and linear probabilities for any number of rounds of a cipher built according to the LTS. To illustrate the effectiveness of the new strategy, we propose Sparx -- a family of ARX-based block ciphers designed according to the LTS. Sparx has 32-bit ARX-based S-boxes and has provable bounds against differential and linear cryptanalysis. In addition, Sparx is very efficient on a number of embedded platforms. Its optimized software implementation ranks in the top-6 of the most software-efficient ciphers along with Simon, Speck, Chaskey, LEA and RECTANGLE. As a second contribution we propose another strategy for designing ARX ciphers with provable properties, that is completely independent of the LTS. It is motivated by a challenge proposed earlier by Wallen and uses the differential properties of modular addition to minimize the maximum differential probability across multiple rounds of a cipher. A new primitive, called LAX is designed following those principles. LAX partly solves the Wallen challenge. [less ▲]

This paper address the design of a phase tracking block for the DVB-S2X user terminals in a satellite precoding system. The spectral characteristics of the phase noise introduced by the oscillator, the channel, and the thermal noise at the receiver are taken into account. Using the expected phase noise mask, the optimal parameters for a second-order PLL intended to track channel variations from the pilots are calculated. To validate the results a Simulink model was implemented considering the characteristics of the hardware prototype. The performance of the design was evaluated in terms of the accuracy and stability for the frame structure of superframe Format 2, as described in Annex E of DVB-S2X. [less ▲]

This thesis covers results from several areas related to symmetric cryptography, secure and efficient implementation and is divided into four main parts: In Part II, Benchmarking of AEAD, two articles will be presented, showing the results of the FELICS framework for Authenticated encryption algorithms, and multiarchitecture benchmarking of permutations used as construction block of AEAD algorithms. The Sparkle family of Hash and AEAD algorithms will be shown in Part III. Sparkle is currently a finalist of the NIST call for standardization of lightweight hash and AEAD algorithms. In Part IV, Cryptanalysis of ARX ciphers, it is discussed two cryptanalysis techniques based on differential trails, applied to ARX ciphers. The first technique, called Meet-in-the-Filter uses an offline trail record, combined with a fixed trail and a reverse differential search to propose long differential trails that are useful for key recovery. The second technique is an extension of ARX analyzing tools, that can automate the generation of truncated trails from existing non-truncated ones, and compute the exact probability of those truncated trails. In Part V, Masked AES for Microcontrollers, is shown a new method to efficiently compute a side-channel protected AES, based on the masking scheme described by Rivain and Prouff. This method introduces table and execution-order optimizations, as well as practical security proofs. [less ▲]

The present paper deals with the design, the repeatability, and the comparison to literature data of a new measuring device called “Rotameter” to characterize the rotational knee laxity or the tibia-femoral rotation (TFR). The initial prototype P1 of the Rotameter is shortly introduced and then modified according to trials carried out on a prosthetic leg and on five healthy volunteers, leading therefore to an improved prototype P2. A comparison of results obtained from P1 and P2 with the same male subject shows the enhancements of P2. Intertester and intratester repeatability of this new device were shown and it was observed that rotational laxities of left and right knees are the same for a healthy subject. Moreover, a literature review showed that measurements with P2 presented lower TFR values than other noninvasive devices.The measured TFR versus torque characteristic was quite similar to other invasive devices, which are more difficult to use and harmful to the patient. Hence, our prototype P2 proved to be an easy-to-use and suitable device for quantifying rotational knee laxity. A forthcoming study will validate the Rotameter thanks to an approach based on computed tomography in order to evaluate its precision. [less ▲]

Hyperbolic metamaterials (HMMs) are anisotropic optical materials supporting highly confined propagating electromagnetic modes. How- ever, it is challenging to tailor and excite these modes at optical frequencies by prism coupling because of the unavailability of high refractive index prisms for matching the momentum between the incident light and the guided modes. Here, we report on the mechanism of excitation of high-index Bloch plasmon polariton modes with sub-diffraction spatial confinement using a meta-grating, which is a combined structure of a metallic diffraction grating and a type II HMM. We show how a one-dimensional plasmonic grating without any mode in the infrared spectral range, if coupled to an HMM supporting high-index modes, can efficiently enable the excitation of these modes via coupling to far- field radiation. Our theoretical predictions are confirmed by experimental reflection measurements as a function of angle of incidence and excitation wavelength. We introduce design principles to achieve a full control of high-index modes in meta-gratings, thus enabling a better understanding of light–matter interaction in this type of hybrid structure. The exploitation of the spectral response of these modes can find applications in bio-chemical sensing, integrated optics, and optical sub-wavelength imaging. [less ▲]

Know your customer (KYC) processes place a great burden on banks, because they are costly, inefficient, and inconvenient for customers. While blockchain technology is often mentioned as a potential solution, it is not clear how to use the technology’s advantages without violating data protection regulations and customer privacy. We demonstrate how blockchain-based self-sovereign identity (SSI) can solve the challenges of KYC. We follow a rigorous design science research approach to create a framework that utilizes SSI in the KYC process, deriving nascent design principles that theorize on blockchain’s role for SSI.

This paper reports on a multilingual course developed and taught at the University of Luxembourg Language Centre in 2015. The Language Centre offers academic language support in English, French and German across the universities three faculties, where most study programmes are bi- or trilingual. The question of how to use existing multilingual resources and support the acquisition of multilingual competences has become increasingly important due to the Bologna agreement and internationalisation strategies at many European universities. However, while research on third language acquisition (Cenoz, Hufeisen, Jessner 2001; Hufeisen, Neuner 2003; Jessner 2008) and multilingualism in higher education (Jessner 2008, Hu 2015; Rindler Schjerve, Vetter 2012) is a common theme, little has been published that could guide language teachers in the design of multilingual courses. Teaching methods such as Intercomprehension with GALANET (Degache 1997) or Eurocom (Meissner 2004; Hufeisen, Marx 2007; Klein 2007) and European projects like CARAP (Candelier 2007) and MAGICC document the need for new concepts in language education very well. Informed by the results of a university wide needs analysis of language competences at the University of Luxembourg, the Language Centre developed a trilingual presentation skills course (FR/EN/GE) for MA students to support second and third language acquisition. In this paper, we will present our course design, comment on the running of the course and present findings from our teaching and student course evaluations that can be used to inform the future teaching of multilingual courses. Our aim is to provide insights into how multilingual courses can be successfully designed and run. Candelier, M. et al. (2007). CARAP.

This paper proposes a decentralized and self-organized agent system for dynamically load-balancing tasks arriving in the form of Bags-of-Tasks (BoTs) in large-scale decentralized systems. The approach is inspired by the emergent behavior of the sandpile model; a cellular automaton behaving at the edge of chaos. Depending on the state of the cellular automaton, rather different responses may occur when a new task is assigned to a resource. It may change nothing or generate avalanches that reconfigure the state of the system. The proportion between the abundance of avalanches and their sizes shows a power-law relation, a scale-invariant behavior that does not need to be tuned. That means that large –catastrophic– avalanches are very rare but small ones occur very often. Such a smart and emergent behavior fits well with the idea of non-clairvoyant scheduling, where tasks are load balanced into computing resources trying to maximize the performance but without assuming any knowledge on the tasks features. In order to study the viability of the approach, we have conducted an empirical experimentation which shows that the sandpile is able to find near-optimal schedules by reacting differently to different conditions of workloads and architectures.

This study introduced a fatigue-based approach to design and implement an indicator channel into an in-tank hydrogen valve. It was aimed at providing a mean to point out multiple early valve’s damages. To achieve the goal, the study was proposed to handle via three main phases. They included (i) the risk point determinations, (ii) the new valve design and the crack nucleation life estimations, as well as (iii) the simplified crack growth analyses. The obtained results firstly highlighted the construction of the test channel (TC), whose branches were located close to the predicted damage’s sites. The damages could be identified either when a crack reaches the TC (then forms a leakage) or indirectly via the crack propagations’ correlation. The results also pointed out that the TC-implemented valve could perform as similarly as the non-TC one in the non-treated condition. More importantly, this new structure was proved to have a capacity of satisfying the required minimal life of 1.5E5 cycles, depending on the combined uses of the specific material and the pre-treatment, among those considered. In addition, the results emphasized the complexity of the TC that could not be formed by the traditional manufacturing process. Hence, direct metal laser sintering was proposed for the associated prototype and the final TC was issued based on the fundamental requirements of the technique. Finally, it was suggested that practical experiments should essentially be carried out to yield more evidence to support the demonstrated results. [less ▲]

This chapter reports on the design, delivery and evaluation of an online research article writing course for doctoral students. The course format was a response to COVID-19 but was designed to be sustainable through enabling flexible, interactive, personalised and independent learning. Its five major components are independent learning tasks, online workshops, writing output, peer review and consultations. Moodle is used for resources and assignments; WebEx for workshops and consultations. Students independently use the e-coursebook to read the theory and submit tasks based on their own texts and articles in their discipline ahead of a workshop on the topic. Additionally, they periodically submit article drafts and engage in peer review. Consultations with the instructor further personalise learning. Having described the course, the chapter goes on to evaluate its affordances and issues by reporting student feedback and teachers’ experiences. It was found that students greatly appreciated the systematic work on their writing in tasks and workshops. However, workshop preparation was very time-consuming for teachers and students would prefer them to be ‘offline’. Furthermore, multidisciplinary peer reviewing and the need to write throughout the course were positively perceived, although requiring greater flexibility in submission times. Consultations were also rated as extremely useful. We conclude with recommendations regarding online course delivery and a blended adaptation for post-COVID purposes. [less ▲]

This paper describes and evaluates a multidisciplinary, online research writing course for PhD students. First, we explain our course rationale and set-up. The core principles are personalised, self-regulated and peer learning, and the optimal use of class time. This is achieved through the following components: an e-coursebook developed in-house; tasks preparing students for the workshops; workshops; writing and reflection; peer review; and individual consultations. Next, we review participants’ feedback from course evaluation surveys. Many students liked the online format although most would prefer the peer review and discussion of theory to happen ‘offline’. A key finding for course efficacy is that students greatly valued working with their own examples in the workshops. They saw this and independent learning tasks as the greatest drivers of their writing development. They also benefited from multidisciplinary peer review. As regards the writing and reflection, all students chose to write on their own and the writing reflection tool was deemed ineffective. We furthermore discuss our (teachers’) perceptions of the affordances and challenges of this course format. On the one hand, it allows workshops to be devoted to collaborative tasks, reflection and data-driven learning. On the other hand, preparing such workshops is very time-consuming, while the multiple components and regular task submissions carry a heavy administrative burden. The paper concludes with how lessons learnt have been implemented into the current course configuration. [less ▲]

This paper describes and evaluates an online research article writing course at the University of Luxembourg. Participants were self-referred PhD students from different disciplines. The aim of the ten-week course is to improve insight into the structural, stylistic and rhetorical features of research articles as well as the writing and publication process. It also provides tools for students to develop their own writing. We will situate our course rationale and design within the literature, then compare these to both the reality of managing and delivering the course online as well as participants’ feedback as reflected in 30 surveys. We will focus on the following results: • The practicability of including multiple pedagogical elements in an online course was challenging. We wanted to integrate both independent and collaborative work, production and reflection. However, results of the surveys and our own experience show that the multiplicity of elements was often seen as complex and difficult to manage and multiple submission deadlines problematic. • Students favoured working alone over working together and uptake of writing groups (Aitchison, 2009) was poor. Multi-disciplinary peer groups were, however, positively reviewed (cf. Hyland, 2012). • The flexibility of the online environment was seen as positive, yet many reported problems finding time to write. However, participants did see the benefit in having to write regularly. Tools of reflection did not score highly. • The personalisation of learning input scored highly in the survey, but this was time-consuming to implement. Whilst instructor-student consultations were offered to further personalise feedback, these had a low uptake (8/30). • We wanted to create a course which included guidance on the writing and publication process (Starfield & Paltridge, 2016) as well as increased genre awareness (Swales, 1990) to prepare students for publication. However, tasks on language and structure were rated more useful by more students than this content. • More participants commented on the benefit of working through their language issues in live sessions over learning how to address language issues through the corpus-tools that were integrated into the course (Charles, 2018). Through sharing this information, we hope to generate a discussion with the audience about ways to optimise online writing courses and manage some of the problems associated with online delivery.

Companies must be able to demonstrate that their way of doing business is compliant with relevant rules and regulations. However, the law often has open texture; it is generic and needs to be interpreted before it can be applied in a specific case. Entrepreneurs generally lack the expertise to engage in the regulatory conversations that make up this interpretation process. In particular, for the application domain of technological startups, this leads to legal risks. This research seeks to develop a robust module for legal interpretation. We apply informal logic to bridge the gap between the principles of interpretation in legal theory with the legal rules that determine the compliance of business processes. Accordingly, interpretive arguments characterized by argument schemes are applied to business models represented by value modeling (VDML). The specific outcome of the argumentation process (if any) is then summarized into a compliance pattern, in a context-problem-solution format. Two case studies in the application area of startups shows that the approach is able to express the legal arguments, but is also understandable for the target audience. The project is presented in two parts; Part I, the background, contains an introduction, literature review, motivational case studies, a survey on legal risks, and a modeling of business and legal aspects. Part II builds on the interdisciplinary facets of the first part to develop the Compliance Patterns Framework which is then validated with two case studies followed by a conclusion. [less ▲]
