abstract = {The great variety of consumer electronic devices with support of wireless communications combined with the emerging Cloud Computing paradigm is paving the way to real anytime/anywhere computing. In this context, many services, such as music or video streaming, are delivered to the clients using Cloud-based providers. However, service continuity when moving across different terminals is still a major challenge. This paper proposes a novel middleware architecture that allows security sessions initiated from one device to be seamlessly transferred to a second one, as might be desirable in the enjoyment of long running media.},

abstract = {There are lots of devices and services inside a home which have to be managed. OSGi platforms alleviate this management by installing some services on a gateway located at home. A service provider might manage those services as part of a package of services. In general, OSGi platforms are connected to centralized repositories facilitating the maintenance by service providers. However, when various service providers work on a given gateway the number of services and components installed in it increases. This sometimes leads to inconsistencies as duplicate components that might cause performance problems or service interruptions. This paper presents a system for analyzing and automatically optimizing the components deployed on a OSGi home gateway.},

abstract = {Privacy is a very complex and subjective concept with different meaning to different people. The meaning depends on the context. Moreover, privacy is close to the user information and thus, present in any ubiquitous computing scenario. In the context of identity management (IdM), privacy is gaining more importance since IdM systems deal with services that requires sharing attributes belonging to users’ identity with different entities across domains. Consequently, privacy is a fundamental aspect to be addressed by IdM to protect the exchange of user attributes between services and identity providers across different networks and security domains in pervasive computing. However, problems such as the effective revocation consent, have not been fully addressed. Furthermore, privacy depends heavily on users and applications requiring some degree of flexibility. This paper analyzes the main current identity models, as well as the privacy support presented by the identity management frameworks. After the main limitations are identified, we propose a delegation protocol for the SAML standard in order to enhance the revocation consent within healthcare scenarios.},

abstract = {Mobile Internet access is becoming more and more pervasive in the new 4G scenarios, where WiMAX is to play a crucial role. WiMax has advantages when considering both energy consumption and bandwidth, when compared with HSDPA and LTE. However, we have found some limitations in IEEE 802.16 security support, which may limit authentication and authorization mechanisms for ubiquitous service development. In this article we analyze weaknesses and vulnerabilities we have found in WiMAX security. WiMax, with the adequate identity management support, could be invaluable for developing new pervasive computing services. We propose the introduction of identity management in WiMAX, as a pervious step to the definition of identity aware WiMax personalization of pervasive computing services.},

abstract = {The approach of users connected anytime, anywhere, has led to merging isolated islands of enriched services environments into the WEB, leaving the user free to choose among an huge number of services. In this context the introduction of ontologies and the creation of semantic Web services mainly focus on using reasoners and planning algorithms to achieve automation in basic processes as discovery, composition and invocation. Nevertheless, there is a problem in standardizing one unique ontology that rises in alignment issues between the domain-specific ontologies on which semantic web service description language eventually rely. Moreover, there is no standardized processes that properly face privacy problem when participants require a graduate disclosure of domain sensitive information. We argue in this paper that a negotiation layer that could connect service consumer and service provider is necessary in order to overcome such limitations. The use of SAML as transverse security language is proposed.},

First commercial services, enabled by ISDN, where mainly operated by Telcos, then IP enabled video conference and multiconference through the session description protocol (IETF RFC 4566). The common explanation why these services were not massively adopted was price, bandwidth limitation and poor usability. Today bandwidth has greatly improved thanks to ADSL penetration, and many free and commercial providers offer more usable video conference services. Still these services are not massively adopted by domestic users. We also base on the hypothesis that video conference integration with social networks and home networks, will dramatically improve usability and market, but we consider that both integration and usability will be greatly increased through flexible consumer electronics. In this article we explain the requirements of such a device, its architecture, and the advantages for users and technology adoption.},

Thus, we are moving a great part of our lives from the physical world to the online world, i.e. social interactions, business transactions, relations with government administrations, etc. However, while identity verification is easy to handle in the real world, there are many unsolved challenges when dealing with digital identity management, especially due to the lack of user awareness when it comes to privacy. Thus, with the aim to enhance the navigation experience and security in multiservice and multiprovider environments the user must be empowered to control how her attributes are shared and disclosed between different domains.With these goals on mind, we leverage the benefits of the Infocard technology and introduce this usercentric paradigm into the emerging NGN architectures. This paper proposes a way to combine the gains of a SAML federation between service and identity providers with the easiness for the final user of the Inforcard System using the well known architectural schema of IP Multimedia Subsystem.},

abstract = {The Future Internet architecture, based on the integration of existing networks and services, and the addition of many new devices like sensors, face a series of important technical challenges, one of them being the management of diverse user identities. The diversity and plethora of the services and procedures affected by the unassociated existing user identities stress the necessity for a holistic solution to deal with the different aspects of the identity management problem. Existing efforts propose limited identity solutions that can only be applied within well defined boundaries and cannot extend their functionality to support converged network environments and service operations across different administrative domains. This paper presents a Dynamic Identity Mapping Association N' Discovery System (DIMANDS) as a holistic identity solution for large scale heterogeneous network environments. This solution offers cross federation identity services and is based on a universal discovery mechanism which spans across different networks, layers and federations. It is also empowered with a unified trust framework which can collect and process diverse trust information to provide trust decisions on a widely accepted format.},

abstract = {Federation has emerged as a key concept for identity management, as it is the basis to reduce complexity in the companies and improve user experience. However, the problem of establishing identity federations in dynamic open environments, where it is desirable to speed up the processes of service provisioning and deprovisioning, has not been fully addressed. This paper reviews the existing frameworks for identity federation, analyzing the underlying trust mechanisms and its suitability to be applied in the mentioned environments. Finally, we propose a generic extension for the Security Assertion Markup Language (SAML) standard in order to facilitate the creation of federation relationships in a secure dynamic way between prior unknown parties.},

abstract = {In this article we present a system for sharing a conditional access module among different visualization devices. Current pay-TV systems require having conditional access modules and smart cards replicated at every visualization device willing to access pay-TV contents. In this article, we show how a home gateway, capable of securely distribute decryption keys, home visualization devices, an inexpensive descrambler, and a home network, enable a flexible solution to access pay-TV.},

DVB-H infrastructure provides a more appropriate content delivery framework that UMTS. Despite this fact, UMTS can play an important role for charging and key distribution for pay-per-view applications by means of the provider SIM smart card.},

abstract = {Trust has emerged as an important facet of inter-domain relationships. Trust management in fixed networks is not functional in ad hoc P2P networks, because these require an autonomous, user-centric and non-static trust management. The trust model is the basis of any security infrastructure. In this paper, we propose a trust-based middleware for secure digital content sharing between pervasive devices. Such middleware allows to enhance security support of pervasive devices. Likewise, we propose a suitable and efficient secure file exchange protocol, WSFEP, for content sharing. Both middleware and file sharing application have been successfuly integrated and tested on PDAs.},
