Abstract
A trusted device includes a secure interface and a host interface, the secure interface being isolated from the host interface by an isolated environment. A trusted source provisions the trusted device via the secure interface to include private information, such as private user information and cryptographic data. When the trusted device is connected to an untrusted host device via the host interface, the untrusted host device transmits a request regarding the private information to a write file of the host interface. A processor of the isolated environment retrieves the request and generates an output, such as an encrypted output, that is responsive to the request from the untrusted host device. The trusted device transmits the output to a read file of the host interface, thus making the output available to the untrusted host device via the host interface. The untrusted host device then receives the output via the host interface.
