Abstract
A method for attesting use of an interactive component during a boot process, comprising the steps of: reading, in response to determining use of the interactive component, associated interactive input; determining whether the input should be trusted; and in response to determining that the input should be trusted, processing the input to create a trusted cryptographic value, further comprising: matching, in response to a subsequent interactive input being read, the subsequent interactive input with one or more of the trusted cryptographic values in order to determine whether the subsequent interactive input is trusted.
