When you picture an architect at work, how do you see them? Holding a pencil over a drawing board, maybe? How about the architects that designed the Morpheus Hotel in Macau; the Gherkin in London, or the Louvre in Abu Dhabi? Still imagining pencils? Architecture, like many other art forms, frequently mirrors the technological advancements of its time, and these are just some examples of the multitude of projects that have been reflecting the increasing integration of computer science in the architectural domain. Today, architects have at their disposal tools that allow them to design, and manage, large-scale and non-conventional design solutions that would have been nearly impossible to conceive using traditional design methods. However, designing with algorithms requires programming, a concept with which practitioners often struggle. For architecture to benefit from computation at large, we still need to close the existing comprehension gap between algorithmic design programs and their behaviour, making this representation method more akin to the traditional architectural practice. The Algorithmic Design Sketchbook proposal addresses this problem by coupling algorithmic design with complementary representation methods that are adequate for designing complex architectural projects, and supporting their synchronisation with a design tool that architects feel comfortable using. https://youtu.be/g_EwyEwf_nc |
IT'S PEOPLE - OR WHY WE NEED AN INTERDISCIPLINARY APPROACH TO CYBERSECURITY - Fabio Greiner | University of Zurich. Supported by SWITCH | Expand |
|---|
In recent years we have come to realise that cyber security not only requires technical measures, but also cooperation on the part of the users in order to make organisations more resilient against cyber-attacks. Changing user behaviour requires more than just one-time training, it demands a different skill set to what most experts in cyber security have. That's why the field is undergoing a transformation through inviting professionals from other disciplines to support security measures. In my master’s thesis I studied the collaboration of security awareness specialists with internal communications. The results from the interviews provided insight into how practiced interdisciplinarity can support security professionals in their daily work, and thus make organisations more secure. https://youtu.be/d3TDiQHaA8I

WHY YOUR INTERNET IS BAD! - Félix Gaudin | UC Louvain. Supported by Belnet | Expand |
|---|
During the Covid crisis I followed my course using Microsoft Teams. In many cases the video/audio quality was really bad, and yet none of the speed tests I ran showed any abnormality. What happened? At that time, speed test websites only measured throughput. Latency is measured as well, but as idle latency (without load on it). However, when you attend a class/meeting there are always other apps/people using your network. We need a way to measure working latency. The IETF has started to develop a new measurement technique called RPM to measure latency under working conditions. Our goal is to implement it in a browser so that every user will know why their connection is poor. Moreover, all current tests work with TCP connections. With TCP it is possible to send a large amount of data, but it's very hard to accurately measure latency or packet losses. Meanwhile, many cloud providers are moving towards HTTP/3 with the QUIC protocol. Therefore, we are developing our measurement tool with QUIC. https://youtu.be/IySU1TIualE

POWERING THE FUTURE: THE VALUE OF RENEWABLE ENERGY COMMUNITIES IN A DECARBONIZED WORLD - João Daniel Correia Brandão | Universidade do Porto - Faculdade de Engenharia. Supported by FCT|FCCN | Expand |
|---|
The transition to renewable energy is critical to mitigate the effects of climate change and achieve a sustainable future. One promising approach to advance this transition is through the development of Renewable Energy Communities (RECs). These communities are formed by groups of people or organisations that come together to produce, consume and share renewable energy locally. They are designed to promote local ownership, collaboration and innovation in the deployment of renewable energy technologies. To fully realise the potential of these communities, assessing their value and impact is essential. This assessment will provide insights into the benefits and challenges associated with RECs, and help identify best practices for their development and implementation. It will also evaluate the economic benefits of these communities, including the potential for job creation, increased economic activity and cost savings for participants. https://youtu.be/oFkGKTDpGqQ

BREAKING DOWN AI TO GET EXPLANATIONS - Karel Hynek | FIT CTU- Czech Technical University, Prague. Supported by CESNET. | Expand |
|---|
Research shows that Artificial Intelligence (AI) can be an effective tool for automated cyber threat hunting. However, the lack of explainability still prevents its mass deployment into commercial-grade tools. Due to AI complexity it's hard to get reasons behind its output, which are crucial for cyber security incident handling and response. We thus bring new design principles of AI by dividing complex monolithic models into small components with defined functionality. By observing the outputs and interaction of these components, we can get an insight into their internal behaviour and provide explanations and reasoning behind their output. The lack of explainability originates from AI's enormous complexity, which people cannot comprehend. We thus divide the complex AI into a component-based system, each component designed separately, like in the human brain. In the brain, there are parts responsible for vision and other parts for hearing for example. We know which part is responsible for what, dramatically increasing our understanding of such a complex system. Component-based models are solutions for AI model deployment in cyber security and other high-stakes areas where explanations are necessary. The division into components provides better control over the predictions and explains them. The improved explainability also reduces the chance of design errors, can improve model quality control and increases the overall trust of its users. Moreover, we can use reasoning to filter out obvious mistakes and increase AI reliability. https://youtu.be/Cbov_mjxyqE

DATA FUSION: THE KEY TO RELIABLE THREAT DETECTION - Richard Plný | Czech Technical University, Prague. Supported by CESNET. | Expand |
|---|
Secure computer networks rely on monitoring, threat detection and security operators who respond to automatically created alerts. Performance of current anomaly and threat detection methods is dependent on the network telemetry data they are developed on. However, in some cases network telemetry does not contain truthful information. An error can occur during transmission, or an attacker can spoof information to confuse threat detectors. As a result, many attacks may remain undetected and false alerts might overwhelm security personnel. We are currently exploring an approach that utilises a combination of several data sources to overcome imperfections. Many state-of-the-art detectors are based on Machine Learning (ML) technology, which can be easily confused. Attackers can alter traffic shape by sending additional data which is unnecessary for communication. Malicious traffic can be completely hidden by this technique and missed by the ML - an outgoing attack might not be detected at all. Data incompleteness is another problem. For example, no blocklist can ever contain every malicious IP address. Moreover, these IP addresses can change over time. Therefore the output of some detectors might not reflect reality. Current techniques, when used separately, are suffering from many pitfalls. https://youtu.be/z2_Gre0wNdA |
JETSTREAM 2.0: A MULTI-FPGA PCIE INFRASTRUCTURE SUPPORTING FPGA-TO-FPGA LINKS - Vladislav Válek | Brno University of Technology. Supported by CESNET | Expand |
|---|
In recent years there has been a major development in the field of cluster computing. These solutions often require many dedicated resources to communicate with each other, and bind their abilities in a collaborative manner. There is also a requirement to allow multiple users to use a single cluster without affecting each others' computations. Nowadays, the FPGAs provide an excellent scalability and programmability for this purpose, with the advantage of parallelism and achieved throughput. This talk introduces the design of a generalised streaming library for the PCI Express interface called JetStream 2.0. It is an enhancement of the previous generation, able to run at the data rates of PCI Express Gen3 x16, that means reaching the transfer speeds of up to 100Gbps. The architecture also supports sending data between two FPGA cards using a zero-copy mechanism - which bypasses the classical buffering of data in RAM and sends them directly to the addressed device. This solution is proposed as vendor independent, thus FPGA cards both from Intel and AMD/Xilinx can be used and also mixed on the host. https://youtu.be/DMPzoBAnln0 |

A Community of Practice (CoP) is a group of people who share a concern or a passion for something they do, learning how to do it better as they interact regularly. vCoP is an online CoP connected through technology and, in this instance, on an Enterprise Social Network (ESN). An ESN is a social network used in enterprise settings to bring together people who share the same interests - using the platform to engage and improve knowledge collectively. It is regarded as Enterprise 2.0. Coming together as a community and working as a unit may help encourage and strengthen the knowledge economy - decreasing isolation and increasing connection, communication and collaboration. https://youtu.be/9s4FXIE5vEM

WHAT CAN WE DO TO PROMOTE BUILT HERITAGE? - Margherita Soldaini | Università degli Studi di Firenze Dip.to di Architettura. Supported by GARR. | Expand |
|---|
Research has highlighted that although learning about cultural heritage still relies on text and pictures, physical objects are more effective, extending beyond conceptual experiences. Virtual representations of 3D objects cannot often support the attributes of physicality that may be valuable, for instance, in the reconstruction processes of a monument. Margherita's research proposes the creation of accessible digital archives and their dissemination and valorisation. The main case study will examine the Church of St. Augustine and the Oratory of Blessed Becchetti in Fabriano, Italy, abandoned after an earthquake in 2016. The church has undergone numerous restorations, but historical evidence allows insight in to its original forms. The digital archive will give easy access to the models of the reconstructive hypotheses, using innovations in research and development in the practice of cultural heritage to ensure high-resolution images, metadata and 3D models. These tools enable us to learn more about abandoned places through the dissemination of content and information, promoting the preservation of the architectural and artistic heritage. Models will be available for download, editing, and 3D printing for interdisciplinary uses, dedicated to visually impaired people, useful for the process of study and comprehensive tactile perception for students, curious people and scholars. https://youtu.be/xYr8Mjb7Di4

CRYPTOGRAPHY FOR CLOUD SECURITY - Martina Palmucci | Università degli Studi di Perugia. Supported by GARR. | Expand |
|---|
Nowadays, the amount of data stored on digital devices is huge and this trend is rising. Because of data protection regulation, and to deter attacks, sensitive data must be protected proactively. Furthermore, recent legislation, among which the General Data Protection Regulation (EU GDPR) and the Consumer Data Right (CDR), has started to mandate technical measures for data protection. In particular, the principle of “data minimisation” states that a data controller should limit the collection of personal information to what is directly relevant and necessary to accomplish a specified purpose. The principle of minimisation can be implemented by limiting access to certain categories of data according to the experts that have to use the data. This research project identified a technological gap related to the data minimisation principle. Although the GDPR legislation provides guidelines, it does not explicitly specify the required techno- logical tools to implement them. The project aims to fill that gap by developing a cryptographic scheme as a service integrated within a cloud system. An encrypted database offers intrinsic data security. Data is transformed into ciphertext (unreadable text) using a cryptographic procedure. Even when an attack on the database would be successful, the encryption techniques prevent hackers to analyze or decrypt your data to use it to their ad- vantage. Specifically, the cryptographic technique that is chosen is Attribute-Based Encryption (ABE). ABE encrypts a resource against attributes instead of concrete users. Only users that possess a correct combination of attributes will be able to decrypt the resource. ABE eases the implementation of access control rules to comply with the GDPR principles. Finally, the last part of the project consists of implementing the cryptographic scheme as a cloud service. Because the cloud is one of the most popular methods for storing data among large communities, we want to integrate the ABE system with cloud storage and other potential cloud services. The envisioned system will integrate the existing Role-Based Access Control (RBAC) system of a cloud system with ABE, allowing data to be encrypted using pre-existing privileges. https://youtu.be/GbnUsx65dVU
