Trust in the P2p Distribution of Virtual Goods

Distribution of virtual goods over the IP based infrastructure offered by the Internet requires efficient techniques w.r.t. to the utilization of the existing resources. One approach here applies methods from the peer to peer domain to ensure that the required traffic mostly is situated in the cost efficient last mile. This paper presents this approach and discusses the security implications. The proposed security and trust architecture includes solutions for integrity protection of data as well as for software on the device, exclusion of manipulated nodes from the network, and isolation between applications by different stakeholders residing in parallel on the same platform. All solutions can be build on existing secure hardware anchors as provided by the Trusted Platform Module (TPM) and its certification infrastructure.
