abstract = {Adhoc networking was initially designed for military application area. But adhoc networks have been found also appealing for autonomous computing. The adhoc mode of IEEE 802.11 (Independent Basic Service Set (IBSS) has not been successful due to several reasons. Within this article we explore and compare two alternatives for adhoc network formation in heterogeneous environments: Wi-Fi P2P also known as Wi-Fi Direct, and Wi-Fi Hotspot. The comparison shows that there are usability, security and performance reasons to favor Hotspot for application development.},

abstract = {IoT, crowd sensing and smart cities will be a traffic challenge. New communication paradigms as asynchronous messaging carry and forward, scheduled delivery and temporary storage will be needed to manage network resources dynamically. Since traditional end to end security will require keeping security associations among devices for a long time draining valuable resources, we propose and evaluate the use of proxy re-encryption protocols in these scenarios as a solution for reliable and flexible security.},

abstract = {This paper focus in an emerging concept called Elastic Personal Computing that is the ability to distribute data processing among multiple personal devices that constitute a mobile cloud. Among the most complex challenges is to provide data layer for the system to exchange input data transparently among nodes considering the data partitioning is application specific. Implementing data layers with replication and load distribution strategies is not feasible due to mobility, intermittent availability and the distributed character of mobile cloud systems. This article reasons about the problem and presents a P2P based data layer for distributed computing using personal devices.},

abstract = {Privacy is close to the user information and thus, present in any ubiquitous computing scenario. In this sense, privacy in identity management is gaining more importance, since IdM systems deal with services that requires sharing attributes belonging to users' identity with different entities across security domains. However, the effective revocation consent -considered as a privacy rule in sensitive scenarios- has not been fully addressed. This article builds on the flexible event-based user consent-revocation mechanism defined in [4] for health care scenarios. In this article we analyze the network dimensioning to calculate the overhead of activating/deactivating attributes and privileges, as subscription and notification event messages exchanged. We consider two main simulation scenarios: a large hospital, and a small-medium hospital.},

abstract = {During the past years we have assisted to the huge diffusion of Cloud based Services, but security and privacy are still an issue in the Cloud due to a problem of trust endemic in the Cloud paradigm; users who have subscribed some kind of Cloud service must fully trust their providers. In this paper we propose a new, yet simple way to guarantee privacy for end user's data and operations. We propose to use an application inside an STB as single point of concentration for user's Cloud services accounts. Thus, a higher degree of privacy could be achieved by splitting user's data and operations over multiple identities and even over multiple providers' networks. In this article we depict, as example, the case of on-line storage and synchronization service.},

abstract = {Video conference services have been there for quite a long time. 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.},

abstract = {Mobile and online DTV encourages new scenarios and applications to dynamically share content or delegate services between user's personal devices and networks. This requires the establishment of federations in a dynamic way, emerging the trust management as an important facet for that. Such trust management should be autonomous, user-centric, and dynamic to cope with forthcoming applications. This article addresses the mentioned requirements, by defining a SAML-compliant enhanced client to support federated environments for cooperation in mobile DTV scenarios. Such client is extended with a trust layer inside consumer electronic devices' software.},

abstract = {With the rapid evolution of networks and the widespread penetration of mobile devices with increasing capabilities, that have already become a commodity, we are getting a step closer to ubiquity. 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.},

DLNA sharing can be extended to include pre and post acquisition protection content at the price of inexpensive descrambler.},
