Pervasive devices interacting in open and dynamic spaces with each others require a mechanism that allows them acting autonomously in a secure way and protecting their resources. Trust is fundamental to establish communication with other users, because the identity is often uncertain and on one's own does not provide trust information, for instance, could(More)
User adaptive systems in the context of pervasive computing can only unveil their power if based on a generic middleware managing private data and context information in combination with flexible device access and control. However, managing those data poses severe privacy problems both legally and from a trust perspective. Therefore we propose a home(More)
Smartcards and PKCS #11 are an appealing solution for combined storage and certificate management at the enduser level. Many applications use PKCS #11 primitives for security reasons: a popular browser, like Netscape Navigator contain a PKCS #11 cryptographic module that plays a critical role in secure web surfing and e-mail signing and encryption.(More)
Trust is considered as a fundamental aspect for inter-domain relationships. We have reviewed existing trust models and their drawbacks when they are applied to pervasive environments. We present PTM, a new decen-tralised trust management model for pervasive computing environments. PTM overcomes the challenges posed by dynamic open environments, making use(More)
— Cloud computing allows accessing resources across Internet transparently: requiring no expertise in, or control over the underlying infrastructure. There is an increasing interest in sharing media files with family and friends. However, UPnP or DLNA were not designed for media distribution beyond the boundaries of a local network and manage media files(More)
In pervasive computing environments, mobile devices communicate via wireless links without requiring any fixed infrastructure. These devices must be able to discover and share services dynamically. In this paper, we propose a new service discovery middleware specifically designed for this kind of environments. This middleware is composed of a service(More)
