abstract = {DLNA can be considered as a good candidate for sharing protected contents among authorized devices. There is a important penetration of DLNA certified devices, and it offers link protection. We identify problems on DLNA's link protection, DTCP-IP, and we propose to improve the authentication and key derivation mechanism. DLNA sharing can be extended to include pre and post acquisition protection content at the price of inexpensive descrambler.},

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.},

abstract = {In this paper we present a system to enable pay-per- view services in mobile handhelds which takes benefits of both DVB-H and UMTS networks. 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 = {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 an unknown user be trustworthy? Nowadays, these devices have a so limited security support. So, we propose a simple trust management model to enhance such support, allowing them interact in ad hoc networks and peer-to-peer applications in a secure way. In this paper, our main contribution is a mathematical and a probabilistic model, as well as demonstrating the model feasibility, since it has been assessed through the prototype implementation, which has been tested in a Pocket PC},
