Fast Centralized Authentication in Wi-Fi HaLow Networks
This paper discusses data interchange formats in the context of heterogeneous networks for the Internet of Things (IoT). The wide dissemination of IoT technologies into various industries, such as agriculture and mining, reveals data transfer issues in geographically remote locations due to absence of any network infrastructure. Several technologies like LoraWAN and NB-IOT offer extended communication ranges, however they still cannot fully solve the problem. In many cases satellite networks are the only available option for transmitting IoT data to a central collection point. Our research of satellite networks showed that as of today the Iridium Short Burst Data (SBD) network is one of the best technologies suited for IoT applications. However, the SBD imposes a significant limit on the size of transmitted messages, which turns data format selection into a vitally important task. We developed a simulation model as well as a heterogeneous Iridium-LoRAWAN prototype to compare different data exchange formats. Our experiments showed more than 4 times increase in the amount of data transferred with Protocol Buffers, compared to the widely used JSON format.
The paper describes a federated identity management infrastructure based on eduroam. This technology enables secure authentication using single netid for network and resources access in eduroam federation. Major protocols and technologies for transparent user authentication are covered. A way of authorization, based on membership in institutional groups and individual user membership is proposed. For user authentication a service provider sends an authentication request contained the encrypted user name and password to user's institute RADIUS server (identity provider). Identity provider is determined by the domain user name/ The authentication request is passed through th eduroam hierarchy of proxy RADIUS servers. If the service provider provides special access for a certain group of users, it also sends a request to group identity RADIUS-server. A request passes through a hierarchy of group RADIUS servers for group membership checking. Eduroam federation and group RADIUS servers hierarchies are based on the domain name system. The implementation of these mechanisms requires a slight modification of service provider RADIUS server for group support and do not require changes of the identity provider and eduroam federations RADIUS servers. Group support is fully compatible with the existing eduroam infrastucture, the both types of RADIUS servers with and without group support can operate simultaneously
The dg.o conference is the flagship conference of the Digital Government Society (DGS), and has positioned itself to be a top-ranking conference in this interdisciplinary academic field. It brings high quality research contributions and plays a major role in the advancement of knowledge in the field of digital government. The continue growing number of scholars and the growing number of members will continue to reinforce the position of DGS as a research and practice platform where researchers and practitioners can meet, exchange ideas, and build new relationships.
This book constitutes the joint refereed proceedings of the 20th International Conference on Next Generation Teletraffic and Wired/Wireless Advanced Networks and Systems, NEW2AN 2020, and the 13th Conference on Internet of Things and Smart Spaces, ruSMART 2020. The conference was held virtually due to the COVID-19 pandemic.
The 79 revised full papers presented were carefully reviewed and selected from 225 submissions. The papers of NEW2AN address various aspects of next-generation data networks, with special attention to advanced wireless networking and applications. In particular, they deal with novel and innovative approaches to performance and efficiency analysis of 5G and beyond systems, employed game-theoretical formulations, advanced queuing theory, and stochastic geometry, while also covering the Internet of Things, cyber security, optics, signal processing, as well as business aspects. ruSMART 2020, provides a forum for academic and industrial researchers to discuss new ideas and trends in the emerging areas.
The unprecedented proliferation of smart devices together with novel communication, computing, and control technologies have paved the way for A-IoT. This development involves new categories of capable devices, such as high-end wearables, smart vehicles, and consumer drones aiming to enable efficient and collaborative utilization within the smart city paradigm. While massive deployments of these objects may enrich people's lives, unauthorized access to said equipment is potentially dangerous. Hence, highly secure human authentication mechanisms have to be designed. At the same time, human beings desire comfortable interaction with the devices they own on a daily basis, thus demanding authentication procedures to be seamless and user-friendly, mindful of contemporary urban dynamics. In response to these unique challenges, this work advocates for the adoption of multi-factor authentication for A-IoT, such that multiple heterogeneous methods - both well established and emerging - are combined intelligently to grant or deny access reliably. We thus discuss the pros and cons of various solutions as well as introduce tools to combine the authentication factors, with an emphasis on challenging smart city environments. We finally outline the open questions to shape future research efforts in this emerging field.
The paper provides an overview and analysis of existing authentication methods in wireless body area networks (WBAN). The novel Bodycom technology is presented. We give a detailed comparative analysis showing advantages and disadvantages of each approach and propose the most appropriate authentication technology.
The article is devoted to identity federations of the research and educational networks. Research and educational networks contain a lot of informational and computing resources. These resources are in a dif-ferent organizational, administrative and public supervision. Scientific resources require authentication, for example, to monitor compliance with intellectual property rights, the definition of user rights, etc. Authorization methods with user authentication by his institution are commonly used. Identity federation is a group of institutions had an agreements on mutual access to their resources, developed a common policy and user identity framework, and implemented them on the organizational and technical level. Identity federation have operational team, steering group and user support service. Due to diversity and international level of the research identity federations cooperates to interfederation. The article describes eduroam and eduGAIN identity federations, based on different authentication technologies. Joint Supercomputer Center of Russian Academy of Sciences (JSCC RAS) is participant of the above projects. JSCC RAS works on creation of identity federation in the Russian research and education community and supports coop-eration with European projects. JSCC supports Eduroam in Russia that is open for participation of any research and education institution.
