Сравнительный анализ методов аутентификации в беспроводных нательных сетях
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 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 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.
Abstract :Telehealth systems demand standardized solutions to be cost effective and to take advantage of middleware operation and interoperability. The plug-&-play and standard-based platform that, either as individual elements or as components, can be incorporated in a simple way into different homecare environments.Many company, not traditionally involved in medical markets, increasing pressure for a standard for Personal Health Devices (PHD). As a result: ISO/IEEE11073 (X73) standards is adapting from Intensive Unit Care (ICU) scope, focused on the Point-Of-Care (PoC), to Personal Health Devices (PHD), focused on ubiquitous environments, implementing high quality sensors, supporting wireless technologies and providing a faster and more reliable communication network resources. This X73-PHD version is for the homecare challenge and might appear the best-positioned international standards to reach this goal. In this article, a X73 compliant agentand manager communication for homecare platform, as a proof of concept, will be explaining all steps implemented as well as on demand agent specific protocol plugins downloaded to X73 Manager.
This book constitutes the refereed post-conference proceedings of the 29th International Workshop on Combinatorial Algorithms, IWOCA 2018, held in Singapore, Singapore, in July 2018.
