Abstract
A secure device operating with a secure tamper-resistant platform including a tamper-resistant hardware platform and a virtual primary platform operating with a low level operating system performing an abstraction of resources of the hardware platform, and a secondary platform with a high level operating system providing a further abstraction of resources to applications in which respective internal hosts are embedded, the secure device including an internal host domain including the internal hosts, the secure device including a plurality of physical and/or logical input/output interfaces through which external hosts can access the internal hosts, the virtual primary platform being configured to set interactions between the external hosts and the internal hosts, wherein the internal host domain includes a further set of virtual hosts each configured to operate as a proxy between an input/output interface and an application, each input/output interface being configured to address only one among the virtual hosts.
