Adaptive System for Collaborative Online Laboratories

Group activities are important aspects of the traditional laboratory experience. A framework using Semantic Web technologies supports collaborative strategies for online laboratories as well.

Interoperability between Heterogeneous Federation Architectures: Illustration with SAML and WS-Federation

Digital identity management intra and inter information systems, and, service oriented architectures, are the roots of identity federation. This kind of security architectures aims at enabling information system interoperability. Existing architectures, however, do not consider interoperability of heterogeneous federation architectures, which rely on different federation protocols. In this paper, we try to initiate an in-depth reflection on this issue, through the comparison of two main federation architecture specifications: SAML (Security Assertion Markup Language) and WS-Federation. We firstly propose an overall outline of identity federation. We furthermore address the issue of interoperability for federation architectures using a different federation protocol. Afterwards, we compare SAML and WS-Federation. Eventually, we define the ways of convergence, and therefore, of interoperability.

Remote laboratories: Proposed guidelines

In this paper, we provide a literature review of modern remote laboratories. According to this state-of-the-art, we explain why remote laboratories are at a technological crossroad, whereas they were slugging for a decade. From various observations based on our review, we try to identify possible evolutions for the next generation of remote laboratories.

Complex federation architectures: stakes, tricks & issues

In this article, we expose the basics of distributed identity management systems and characterize what makes an identity federation architecture a singular one. We depict the evolutions and current trends of the interconnection of information systems by exposing what could be a global identity management system issued from the convergence of multiple identity federations. Thereby, we expose the expected functionalities of such an architecture and we also describe the basic distributed identity management mechanisms necessary for their deployment. Then, we discuss about privacy concerns and why some of these functionalities should be implemented carefully.

PRIVACY FOR RFID-ENABLED DISTRIBUTED APPLICATIONS - Design Notes

The concern of this paper is RFID systems coupled with distributed applications. We do not treat known RFID attacks, we rather focus on the best way to protect the identity mapping, i.e. the association of a tag identifier, which can be obtained or deduced from the tags or communications including the tags, and the real identity of its carrier. We rely on a common use case of a distributed application and a modelling approach.

The User-Centric Vision Matches Credentials Exchanges

The users must face two main concerns in their digital lives, interactions and privacy, especially in identity federation architectures. Their environment and requestor client largely influence these concerns. A rich user environment issued from a user-centric vision on identity management architectures may be helpful for usability and privacy. In this paper we expose facts about the identity federation and the user digital life concepts. We then shape a user environment dedicated to identity management, and we establish some assumptions about future user environments and identity credentials implementations.

Reusability in practice for Remote Laboratories

In this paper, we present a new device brought online thanks to our Collaborative Remote Laboratories framework. Whereas previous devices integrated in our remote laboratory belongs to the domain of electronics, such as Vector Network Analyzers, the device at the concern in this paper is an antenna workbench. Because the middleware and framework for our environment were designed to be reusable, we wanted to illustrate these qualities by providing a completely new device in our Online Engineering catalog. After presenting the device to be put online, we will expose the software development efforts required in regards to the reusability of the solution.

Contribution in Adaptating Web Interfaces to any Device on the Fly: The HCI Proxy

Lot of work has been done on the adaptation of UIs. In the particular field of Web UI adaptation, many research projects aim at displaying web content designed for PCs on poorer supports. In this paper, we present previous work in the domain and then our proxy architecture, HCI proxy, to test solutions for the problem of adapting Web UIs for mobile phones, PDA and smartphones but also for TVs through browser‐embedding STBs, and this on the fly.
