To stay ahead of the next cyber threat we’re always creating new innovations and patenting new products. Many of our patents are listed below:

Providing Trusted Virtual Secure Cryptoprocessors for Guests

Patent Number: 11,645,101
Provision of a virtual secure cryptoprocessor (VSC) for a guest virtual machine (VM), part of a first guest, of a hypervisor of a computer system, includes (i) storing guest VM state and VSC state together in an encrypted virtual hard disk drive file, (ii) storing a decryption key in a sealed partition, of a second guest, sealed against a physical secure cryptoprocessor, (iii) based on verifying that a host computing environment of the computer system is in a trusted state and on booting the hypervisor thereon, unsealing the sealed partition of the second guest, the unsealing providing the decryption key, and decrypting the encrypted virtual hard disk drive file using the decryption key, where the decrypting decrypts the stored guest VM state for execution of the guest VM and decrypts the VSC state to provide the VSC for use by the guest VM.

Inventor:  Joel Upham and Richard Turner

CODE PROTECTION

Patent Number: 11,550,883
A method that includes receiving a request to execute bytecode that corresponds to secured program code, the secured program code including an encrypted version of the bytecode. Based on receiving the request to execute the bytecode, the method resolves the request, the resolving including identifying a location on disk of the secured program code. Based on resolving the request, a license file for decrypting the encrypted version of the bytecode for execution is assessed, the license file including an encrypted key-value. The encrypted key-value is used in decrypting the encrypted version of the bytecode to obtain decrypted bytecode, where the decrypting places the decrypted bytecode in working memory, and the decrypted bytecode is executed.

Inventor: Adam Meily

Behavioral Biometric Feature Extraction and Verification

Patent Number: 11,449,746
Description: Behavioral verification of user identity includes building a deep neural network for gait-based behavioral verification of user identity. The building includes receiving movement data describing movement, in multiple dimensions, of computer system(s) of user(s), the movement data including sensor data acquired from sensor(s) of the computer system(s). The building further includes performing pre-processing of the movement data to provide processed movement data for processing by a deep neural network to extract local patterns and training the deep neural network using the processed movement data. The method also includes providing the trained deep neural network for gait-based behavioral verification of user identity based on determinate vectors output from the trained deep neural network.

Processor Core Isolation for Execution of Multiple Operating Systems on a Multicore Computer System

Patent Number: 11,397,587
Description: Process core isolation for execution of multiple operating systems on a multicore computer system includes booting first and second operating systems (OSs) on a computer system that includes a plurality of processor cores across physical central processing unit(s) (CPUs). Booting the first OS boots the first OS on a first subset of the processor cores. Booting the second OS, different from the first OS, boots the second OS on a second subset of the processor cores. The first and second subsets are mutually exclusive, where a first processor core of a physical CPU of the physical CPUs is included in the first subset and a second processor core of the physical CPU is included in the second subset, and where the first and second OSs execute concurrently on the computer system, and each of the first and second OS executes on only its respective subset of processor core(s).
Awarded: July 26, 2022
Inventors: Rian Quinn, Connor James Davis, Harlan Philip White, Erin Grace Riley Hensel

Dedicating Hardware Devices to Virtual Machines in a Computer System (Beam)

Patent Number: 10,938,784
Description: Dedicating Hardware Devices to Virtual Machines includes dedicating, by a hypervisor executing on a computer system, a set of hardware devices of the computer system to a first virtual machine of the hypervisor, the first virtual machine executing a guest operating system, and the set of hardware devices for use by the guest operating system in execution of the guest operating system, and dedicating network device hardware of the computer system to a second virtual machine of the hypervisor, the second virtual machine being a different virtual machine than the first virtual machine, wherein network communication between the guest operating system and a network to which the computer system is connected via the network device hardware occurs via the second virtual machine.
Awarded: March 2, 2021
Inventors: Christopher Patterson, Rian Quinn, Katherine Temkin, Harlan White

On-GPU Compositioning of Graphical Data From Multiple Domains
Patent Number: 10,572,207
Description: On-GPU Compositioning of Graphical Data From Multiple Domains is a technique for combining application windows from different VMs onto a single graphics card, and doing that combination on the graphics card itself. Previously the combination occurred on the CPU itself before being transmitted to the graphics card, incurring a significant performance penalty.
Awarded: February 25, 2020
Inventors: Jonathan Farrell, Rodney Forbes, Maurice Gale, Brendan Kerrigan, Rian Quinn, Sandy Stutsman

Entity Resolution-Based Malicious File Detection
Patent Number: 10,754,950
Description: Entity Resolution-Based Malicious File Detection uses advanced machine learning and artificial intelligence techniques to automatically model normal behavior of document viewers to quickly identify suspect documents before they compromise a network. TAFFI is a user-friendly endpoint defense solution that the Department of Defense and other transition partners can use to protect their systems against malware-laden documents.

Deployment and Installation of Updates in a Virtual Environment

Patent Number: 9,996,374
Description: An update is deployed to a guest virtual machine of a hypervisor during runtime of the guest virtual machine. An executing thread of the guest virtual machine is identified and execution of the thread is redirected to a function to open a handle to a file, of the guest virtual machine, to which data of the update is to be written. The data is provided to a component of the guest virtual machine, and then execution of the thread is redirected to a function to write the data provided to the component to the file.
