Optimización de redes mediante un mejor iBGP

This project seeks to achieve a systematic approach to internal BGP (iBGP) mesh design within an Autonomous System (AS). These meshes are an integral part of the operation of any large-scale network on the Internet. A good iBGP design within an AS is essential to take optimal advantage of the available paths.

The general objective of the project is to apply a systematic approach to the analysis of BGP traces to different reference cases, using the techniques previously developed, and incorporating other approaches, based on accessibility and distance to the different Autonomous Systems that make up the Internet, which today exceeds 70,000, and propose a methodology for Internet operators to optimize their networks. The project will seek a theoretical foundation for this behavior and connections with other existing lines of research.

The main impact of the proposal is to support the design of regional transit networks with methodological tools, derived from formal models.

Indeed, the methodology and set of tools developed makes available to operators optimized results that do not depend on acquiring infrastructure and/or additional and proprietary software, but on a methodologically assisted design to make the best use of standardized technology and ensure better access to the Internet by users in the region.

Seguridad en el enrutamiento utilizando tecnología Blockchain

The general objective of the project is to analyze the properties of blockchain and its specific application in the assignment and delegation of resources of the Internet infrastructure, as well as in the security of external BGP routing against Route Hijacking or similar attacks.

To carry out a route hijacking attack, no vulnerability or protocol flaw is exploited, but rather the fact that the BGP architecture is based on mutual trust is exploited. For this reason, these attacks are as old as the protocol itself, and today these failures continue to occur and the best strategy to provide routing security on the Internet continues to be investigated.

Current solutions such as RPKI are generating risks due to the centralization of critical information in the RIRs promoted by current management models. This work seeks to implement a model with a tamper-proof decentralized infrastructure (based on blockchain), where thanks to the deployment of a decentralized application (intelligent contract) it is possible to provide security in the allocation of Internet resources, and the subsequent use of that stored information to provide security to the BGP protocol.

Janus – Framework para Gestão de Identidades e Acesso Descentralizado em Arquiteturas Zero Trust Network Access para a Internet das Coisas

With the aim of providing a new approach to identity management, which gives device owners greater control over their assets and strengthens a zero-trust network, Instituto Atlântico proposes Janus, a project that consists of developing a framework that allows issuing and managing Blockchain decentralized identities (DIDs) for devices and users of Internet of Things [IoT] solutions in a universal and interoperable way on Zero Trust Network Access (ZTNA) architectures and easy to integrate with different IoT device management platforms such as AWS IoT Core, IBM Watson IoT, Fiware and others. Initially in this project, they will be integrated with the Brazilian open source platform for IoT solutions; the Dojot.

DIDs enable a standards-based, globally interoperable identity system that puts IoT device owners out of control. DIDs allow the creation of multiple identifiers to help manage anonymity, auditability, correlation between contexts, privacy, revocability, and traceability. A decentralized ID management system eliminates the need for any central government authority and paves the way for new models of trust between organizations and people, as it is based on the blockchain network, cryptography, and the Zero-Knowledge Proof Protocol ( ZKP). All this provides more transparency, improves communication and saves costs.

Janus intends to provide a framework that enables the development of a cracked access with authentication and authorization mechanism, allowing device donations to define access rules for users and devices, including data access and sharing, while ensuring confidentiality. of the data. users who can trade on IoT networks, in addition to protecting them from other types of attacks such as DDoS attacks.

Reducing the Digital Divide in Vulnerable Populations in the City of Córdoba Using WIFI and Unlicensed LTE Technology

The goal of the project is to reduce the digital divide in vulnerable areas of the city of Córdoba with little or no Internet access, using LTE base stations operating on unlicensed frequency bands for point-to-multipoint links. Thus, it seeks to enable access to the various services available online, including education, health, public services, and access to the Digital Neighbor (VeCi) and Digital Citizen (CIDI) platforms.

The project format allows its replication in different municipalities, as well as in other provinces. Its main focus is to reduce the digital divide. In this sense, any jurisdiction can develop a similar project adapted the characteristics of each city (example: by identifying its own citizen participation centers). The proposed technology only requires electricity for CPEs as it is uses LTE, can reach several places in just a few days, and can be adapted to different modalities and, therefore, to different geographical locations.

Community Communications Networks for Strengthening the Circular Economy and Social Exchange in La Macarena, Meta

Seeking to promote a transformation in the relationship fabric that bonds the actors of the agro-ecological and tourism sectors, this project proposes strengthening community initiatives and alternative economy processes in the municipality of La Macarena-Meta, prioritizing the participation of women and the strategic use of information technologies.

To do so, the project will work on the collective design of a community communications network and its social, financial, and technological components, leveraging the Community Networks Kit developed by Colnodo. It will also implement an open-source digital platform hosted on the community network to facilitate the exchange of local products and services based on solidarity and circular economy dynamics.

LibreRouter V2.0: Evolving Technological Sovereignty

This project seeks to provide continuity to the LibreRouter stack, a series of hardware, software, documentation, and audiovisual support designed to technically and socially facilitate the development, deployment, management, and expansion of community networks. LibreRouter was created with funding provided by FRIDA and was the first project to be selected in two regions (the second being Africa – FIRE). As a result of its success over the years, communities on all continents are choosing to use this technology today.

The goal of this project is to redesign LibreRouter with state-of-the-art technology, as this will allow: (i) avoiding the decreased availability of LibreRouter V1.0 components, which has a negative impact on its cost and production times; (ii) taking a qualitative leap in terms of performance and energy efficiency, so that, in the future, this can continue to be a high-performance option; and (iii) incorporating changes that have been identified over years of deployment experiences in various scenarios.

4G Community Network

In Mexico, approximately 12 million people do not have access to mobile or fixed bandwidth, and this substantially limits their chances of being informed and participating in the global economy and society. In terms of aggregate mobile coverage (including 2G, 3G, and 4G technologies), rural areas with less than 10,000 inhabitants are the most affected.

This project seeks to develop a community mobile communication system using 4G/LTE technology, open-source software, and reused hardware. It also includes a network management system that will be integrated into the system currently used by 2G/GSM community mobile telephone networks. From a technical and social perspective, innovation is not limited to reducing the digital divide for remote communities. Instead, innovation also includes doing this in a way that will allow the community to be its own communications system provider, encouraging their active participation in the operation, management, and transformation of technology into something that truly meets their needs.

Pilot Project for Television White Space Technology in Montes de María, Colombia

This initiative comprises the design, implementation, and maintenance of a telecommunications network using Television White Space Technology to provide connectivity services for eight public schools located in the rural areas of the municipality of Ovejas (and the communities settled in their surroundings), in the department of Sucre, Montes de María subregion, in Colombia.

This pilot project had three clearly defined functional goals:
1. To confirm the ability of the TVWS signal to coexist after installing the technology in a telecommunications base station, in the same location as the signal of five national television broadcasters, public and commercial radio services, microwave links, cell phone services, and trunking.
2. To verify the performance of the TVWS technology on site, confirming its ability to serve clients in rural, difficult-to-access areas (mountainous regions with dense foliage typical of the Colombian territory) and assess connection speed and latency.
3. To generate an impact on the education sector in the pilot project’s area of influence, assessing the functionality of the service in very difficult-to-access rural schools and evaluating the connection’s stability and quality compared to the use of collaborative tools and the consumption of audio and video content as well as video calls.

Data Protection System Based on Anonymization Techniques and in Accordance with Privacy Laws

Given that the trend among companies and government institutions is to deploy online and cloud services to modernize their business models, they may be vulnerable to intrusion attempts and data leaks.

This project proposes an innovative way to protect sensitive user data for different customers (private companies, government agencies, among others) through anonymization techniques and cloud computing. This solution advances existing state-of-the-art solutions for data leak mitigation and helps companies and government agencies comply with privacy laws.

This initiative will implement a cloud-based prototype to enable higher-capacity processing without burdening the computing capacity of local devices and servers in private businesses and government institutions. The project seeks to increase security and privacy levels in existing technological solutions, to ensure the self-sovereignty of data owners, and to provide a solution for companies, government institutions, and individuals to meet the requirements of privacy laws.

Promotion and Appropriation of Digital Rights to Guarantee Access to Information in Indigenous Languages

The expansion of community networks, the increasingly mandatory use of digital tools, and the rapid isolation caused by the Covid-19 pandemic have left indigenous communities vulnerable with respect to the protection of their personal and collective information.

This initiative seeks to enable the participation of indigenous peoples in digital environments, through the promotion and appropriation of digital rights, to guarantee access to information in indigenous languages in the Triqui, Mazateco, Mixe, and Zapoteco regions that are part of the cultures recognized in the Law on the Rights of the Peoples and Communities of the State of Oaxaca. This proposal provides tools to help mold digital (Internet) environments to indigenous needs and culture, by means of training workshops and a campaign in public and community media. The ultimate goal of this project is the governance of community data and the presence of linguistic diversity on the Internet, including the right of the indigenous peoples and communities of the Oaxacan entity to decide what is shared or maintained in cyberspace.
