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
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. The 31 regular papers presented in this volume were carefully reviewed and selected from 69 submissions. They cover diverse areas of combinatorical algorithms, complexity theory, graph theory and combinatorics, combinatorial optimization, cryptography and information security, algorithms on strings and graphs, graph drawing and labelling, computational algebra and geometry, computational biology, probabilistic and randomised algorithms, algorithms for big data analytics, and new paradigms of computation.
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.
