PlonKup: Reconciling PlonK with plookup
Pearson, Luke; Fitzgerald, Joshua; Masip Ardévol, Héctor; Ballés Muñoz, Marta; Muñoz Tapia, José Luis
In 2019, Gabizon, Williamson, and Ciobotaru introduced PlonK – a fast and flexible ZK-SNARK with an updatable and universal structured reference string. PlonK uses a grand product argument to check permutations of wire values, and exploits convenient interactions between multiplicative subgroups and Lagrange bases. The following year, Gabizon and Williamson used similar techniques to develop plookup – a ZK-SNARK that can verify that each element from a list of queries can be found in a public lookup table. In this paper, we present PlonKup, a fully succinct ZK-SNARK that integrates the ideas from plookup into PlonK in an efficient w

Mientras que esas definiciones reflejan los requisitos básicos de IoT, las nuevas definiciones de IoT dan más valor a la necesidad de redes ubicuas y autónomas de objetos donde la identificación y la integración de servicios desempeñan un papel importante e inevitable.

Moodle y Google Workspace, integración y convivencia en la UPC
Alcober Segura, Jesús Ángel
En la UPC hay una larga tradición de utilizar Moodle, con su plataforma Atenea, desde hace varios años. A partir del mes de marzo pasado, a la par de la pandemia, se incorporó para todos los estudiantes y profesorado Google Workspace (antigua G Suite), con todas sus herramientas de correo, calendario, archivos, chat, videoconferencia, ... Desde entonces se ha usado tanto Moodle como Google Workspace de forma paralela. Desde la UPC se ve necesario analizar las posibilidades de integración o convivencia de ambos entornos que dan servicio a la docencia, y en esta sesión se explicará qué posibilidades se están vislumbrando. Es una sesión también para abrir el debate en torno a este tema candente

Tips and tools to automate OMNeT++ simulations and to facilitate post data management tasks
Lemus Cárdenas, Leticia; Astudillo León, Juan Pablo; Barbecho Bautista, Pablo Andrés; Aguilar Igartua, Mónica
Nowadays, network simulators are frequently used by researchers to work with different kind of communication networks. In this context, the objective of this work is to introduce the user to the main used simulation tools for wireless networks, in particular vehicular ad hoc networks (VANETs). In this report, we gather some useful tools and tips for researchers, including installation and operation of OMNET++, SUMO and VEINS. We think this information will be useful for new users and will save them a lot of time and effort at the beginning of their research works. For this, we have used a widely known distribution of Linux (Ubuntu 16.X). We describe how to integrate simulators OMNET++, VEINS, and SUMO to test vehicular communication protocols and services in an urban environment. This tutorial includes a virtual machine as additional material to help researchers. Our final objective is to assist researchers with their tasks associated to the development of novel proposals that require to perform simulations to show the benefits of their approaches.
Report with tips and tools for PhD students who need to start working with tools like OMNeT++, SUMO; OpenStreetMaps. We collect here a list of tips to help them to speed up the learning process. Also, we introduce the researcher to machine learning techniques focusing on neural networks. We give tools, references and useful examples to start with. Finally, we also comment how to use latex editors easily.

IPv6 Mesh over BLUETOOTH(R) Low Energy using IPSP
Gómez Montenegro, Carlos; Darroudi, Seyed Mahdi; Savolainen, Teemu; Spoerk, Michael
RFC 7668 describes the adaptation of 6LoWPAN techniques to enable IPv6 over Bluetooth low energy networks that follow the star topology. However, recent Bluetooth specifications allow the formation of extended topologies as well. This document specifies mechanisms that are needed to enable IPv6 mesh over Bluetooth Low Energy links established by using the Bluetooth Internet Protocol Support Profile. This document does not specify the routing protocol to be used in an IPv6 mesh over Bluetooth LE links.

Deliverable DJRA1.3: Tool prototype for creating and stitching multiple network resources for virtual infrastructures
Cervelló Pastor, Cristina; Monje Hernández, Álvaro; Óskarsson, Ásgeir
This document reports the final results of JRA1.2 Activity in the development of a tool prototype for creating sets ofvirtual resourcesinFEDERICA.The prototype goal is to simplify and automate part of the work for NOC.The tool may also serve,with different privileges, a FEDERICA user to operate on his/her slice. The tool described here was designed with the objective of providing an interactive application with a graphical interface to operate on resources for the NOC and the end users (researchers). The tool simplify the creation and configuration of resources in a slice and it is a mandatory step to ensure scalability of the NOC effort. It offers an interactive Graphical User Interface that translates the users’ actions to commands in the substrate (networknodesandV-nodes)andslice elements(VirtualMachines).User accounts may be created for the NOC and for researchers, each with specific privileges to enable different sets of capabilities. The NOC account has full access to all the resources in the substrate, while each user’account has full access only to the virtual resources in his/her slice. The tool has been developed using the Java programming language as Open Source code and relies on the open source Globus® Toolkit. Testing has been performed in a laboratory environment and on some FEDERICA substrate equipment (1switch, 2VMwareServers) in their standard configuration. For testing the router, web services and GUI an additional computer was used, using a public IP address.
This document describes the prototype FEDERICA Slice Tool developed for the virtualization of network elements in FEDERICA and for creating and stitching network resources over this virtual infrastructure. An SNMP-based resource discovery prototype is also introduced as a new functionality to be integrated in the tool.The deliverable also presents aviability study for the use of traffic prioritization in the FEDERICA infrastructure and some network performance measurements on a real slice within FEDERICA.
