Patent attributes
A secure provisioning manifest used to authenticate and securely communicate with peripherals attached to a computer is provided with techniques to withdraw the authentication and terminate the secure communications with any peripheral when operating parameters for the peripheral indicate that there is a security threat associated with 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 establish a secure encrypted session for communicating with each peripheral attached to the computer when a peripheral is authenticated and able to establish a secure encrypted session. The secure I/O module uses current and known operating parameters for each peripheral to periodically determine if a peripheral has been compromised by a security threat.
