Patent ID: 8479021

Claim:
A method for generating an n-bit result comprising: receiving, by a secure containment device (SCD), a request to generate the n-bit result, wherein the request comprises an n-bit generator input and a master secret identifier and wherein the request is sent from an application executing on a host system using a first input/output (I/O) interface; disabling, by the SCD, all I/O interfaces on the SCD between the host system and the SCD after receiving the request from the host system; after disabling all the I/O interfaces on the SCD between the host system and the SCD: providing, by the SCD, the n-bit generator input and the master secret identifier to a secured hardware token over a second I/O interface; receiving, by the SCD, the n-bit result from the secured hardware token over the second I/O interface; enabling, by the SCD, at least the first I/O interface after the n-bit result is generated; and providing by the SCD, after enabling the first I/O interface, the n-bit result to the application using the first I/O interface.
