Abstract
An IC chip can provide silicon root of trust (RoT) functionality. In described implementations, the IC chip includes a processor, an alert handler, and multiple peripheral devices, which generate alert indications. The alert handler processes the alert indications, which have security implications. The alert handler includes multiple alert receiver modules to communicate with the multiple peripheral devices. The alert handler also includes a controller, multiple accumulation units, multiple escalation timers, and multiple escalation sender modules. These components can be organized into a hierarchy of increasing escalation severity. In operation, the controller classifies an alert and flexibly implements an adaptable alert handler path that is established through the escalation components responsive to the classification and based on a source of the alert. A path can conclude with an escalation sender module commanding an escalation handler to implement a security countermeasure. The flexible paths can therefore handle different types of alerts.
