Publication number: 20210133313Abstract: Integrity verification of a containerized application using a block device signature is described. For example, a container deployed to a host system is signed with a single block device signature. The operating system of the host system implements an integrity policy to verify the integrity of the container when the container is loaded into memory and when its program code executes. During such events, the operating system verifies whether the block device signature is valid. If the block device signature is determined to be valid, the operating system enables the program code to successfully execute. Otherwise, the program code is prevented from being executed. By doing so, certain program code or processes that are not properly signed are prevented from executing, thereby protecting the host system from such processes. Moreover, by using a single block device signature for a container, the enforcement of the integrity policy is greatly simplified.Type: ApplicationFiled: October 31, 2019Publication date: May 6, 2021Inventors: Md Nazmus Sakib, Jeffrey A. Sutherland, Deven Robert Desai, Jaskaran Singh Khurana, Scott Randall Shell, Jessica M. Krynitsky

Publication number: 20200355868Abstract: Accelerating photonic and opto-electronic technologies requires breaking current limits of modern chip-scale photonic devices. While electronics and computer technologies have benefited from “Moore's Law” scaling, photonic technologies are conventionally limited in scale by the wavelength of light. Recent sub-wavelength optical devices use nanostructures and plasmonic devices but still face fundamental performance limitations arising from metal-induced optical losses and resonance-induced narrow optical bandwidths. The present disclosure instead confines and guides light at deeply sub-wavelength dimensions while preserving low-loss and broadband operation. The wave nature of light is used while employing metal-free (all-dielectric) nanostructure geometries which effectively “pinch” light into ultra-small active volumes, for potentially about 100-1000× reduction in energy consumption of active photonic components such as phase-shifters.Type: ApplicationFiled: May 8, 2020Publication date: November 12, 2020Inventors: JUDSON D. RYCKMAN, NAZMUS SAKIB

Publication number: 20200274939Abstract: The present disclosure concerns systems and methods for generating application-control policies. A system may receive application-usage data for a set of devices. The application-usage data may identify binaries with which a user interacted. The system may determine one or more application-usage characteristics for one or more devices in the set of devices based at least in part on the application-usage data and may rely solely on data associated with the binaries with which the user interacted. The system may identify a set of candidate devices based on the one or more application-usage characteristics. The application-usage characteristics may include a measure of distinct applications used during a specified time period and a measure of variability of application usage across a set of specified time periods. The system may generate an application-control policy for the set of candidate devices based on application-usage data for the set of candidate devices.Type: ApplicationFiled: February 26, 2019Publication date: August 27, 2020Inventors: Md.

Patent number: 10268816Abstract: A system for changing policy information of a process is provided. When a process is to execute, the system stores policy information for the process in association with the process code. The system also creates a token for the process. The token provides evidence of the policy for the process and includes at least a reference to the stored policy information. The system provides the token to the process for use by the process as evidence of the policy for the process. When the process provides the token to a service provider, the service provider uses the reference to access the policy information for the process. While the process is executing, the system modifies the stored policy information. When the process subsequently provides the token to a service provider, the service provider uses the reference to access the modified policy information for the process.Type: GrantFiled: March 31, 2016Date of Patent: April 23, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Md.

Publication number: 20180103097Abstract: An application is installed on a computing device from an application package. An origin of the application (e.g., a managed installer for an enterprise, a reputation checking service) is propagated to files written to a storage device of the computing device as part of the installation, such as by writing origin information to the storage device as metadata associated with the file. The origin information for a file, in conjunction with a policy on the computing device specifying one or more trusted origins for applications on the computing device, is used to identify whether a particular action can be taken with and/or by the file. These actions can include, for example, execution of an application from an executable file. If the origin information for a file indicates an origin that is a trusted origin specified by the policy, then the action can be performed.Type: ApplicationFiled: October 7, 2016Publication date: April 12, 2018Applicant: Microsoft Technology Licensing, LLCInventors: Scott R.

Patent number: 9281902Abstract: Broadband access networks are driving the upgrade of DWDM networks from 10 Gb/s per channel to more spectrally-efficient 40 Gb/s or 100 Gb/s. Signal quality degradation due to linear and non-linear impairments are significant and error control coding and signal processing solutions play increasingly key roles in meeting increasing demand, providing improved quality of service, and reduced cost. It would be beneficial to reduce the power consumption of optical receivers for optical links exploiting for example LPDC encoding. Accordingly, the inventors have established a low complexity soft-decision front-end compatible with deployable LDPC codes in next-generation optical transmission systems. Beneficially the optical receiver design can be retro-fitted into deployed hard-decision based optical systems and replaces the 3-to-2 encoder of the prior art in the electrical portion of the receiver with a single gate design. Further, the design may act as a 2-bit Flash ADC in multimode fiber based optical receivers.Type: GrantFiled: April 24, 2013Date of Patent: March 8, 2016Assignee: The Royal Institution for the Advancement of Learning/ McGill UniversityInventors: Odile Liboiron-Ladouceur, Meer Nazmus Sakib
