Abstract
A secure provisioning manifest used to authenticate and securely communicate with peripherals attached to a computer is provided with techniques to learn about a new peripheral not authorized to be attached to the computer and possibly gain authorization for the peripheral. A secure I/O module, that is separate from an operating system and transaction software executed by a processor of the computer, uses the secure provisioning manifest to authenticate and establish a secure encrypted session for communicating with each peripheral authorized to be attached to the computer. When an unauthorized peripheral is found, identifying information for the peripheral is transmitted to an enterprise provisioning server with a request to authorize the peripheral.
