Publication number: 20220292228Abstract: 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.Type: ApplicationFiled: October 31, 2020Publication date: September 15, 2022Applicant: Google LLCInventors: Scott D.

Publication number: 20220292226Abstract: An IC chip can provide silicon root of trust (RoT) functionality. In described implementations, the IC chip includes a processor, an interconnect, and multiple peripheral devices. These comportable circuit components are designed to facilitate interoperability and consistent, expected communications for security circuitry. Each peripheral device includes an interface that adheres to a common framework for interacting with the processor and with other peripheral devices. The interface includes an interconnect interface coupling the peripheral device to the interconnect and an inter-device interface coupling the peripheral device to at least one other peripheral device. The peripheral device is realized based on a peripheral device design code that indicates inter-device signaling in accordance with an inter-device scheme of an interface specification.Type: ApplicationFiled: October 31, 2020Publication date: September 15, 2022Applicant: Google LLCInventors: Scott D.

Patent number: 10547871Abstract: The disclosure provides an approach for edge-aware spatio-temporal filtering. In one embodiment, a filtering application receives as input a guiding video sequence and video sequence(s) from additional channel(s). The filtering application estimates a sparse optical flow from the guiding video sequence using a novel binary feature descriptor integrated into the Coarse-to-fine PatchMatch method to compute a quasi-dense nearest neighbor field. The filtering application then performs spatial edge-aware filtering of the sparse optical flow (to obtain a dense flow) and the additional channel(s), using an efficient evaluation of the permeability filter with only two scan-line passes per iteration. Further, the filtering application performs temporal filtering of the optical flow using an infinite impulse response filter that only requires one filter state updated based on new guiding video sequence video frames.Type: GrantFiled: May 5, 2017Date of Patent: January 28, 2020Assignees: Disney Enterprises, Inc., ETH Zurich (Eidgenoessische Technische Hochschule Zurich)Inventors: Tunc Ozan Aydin, Florian Michael Scheidegger, Michael Stefano Fritz Schaffner, Lukas Cavigelli, Luca Benini, Aljosa Aleksej Andrej Smolic
