Publication number: 20240113867Abstract: A distributed control system includes an electronic control unit to establish secure communication with a distributed control module. Upon determination that a previously negotiated session key is stored on the electronic control unit, the electronic control unit transmits encrypted communications with the distributed control module using the previously negotiated session key, negotiates a new session key with the distributed control module, and stores the new session key. Upon determination that the previously negotiated session key is not stored on the electronic control unit, the electronic control unit negotiates the new session key with the distributed control module. After negotiating the new session key with the distributed control module, the electronic control unit ceases transmission of unencrypted communications with the distributed control module, transmits encrypted communications with the distributed control module using the new session key, and stores the new session key.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Applicants: General Electric Company, BAE Systems Controls Inc.Inventors: Jeffrey S. Gilton, Matthew B. Pfenninger, Douglas R. Nichols, Russell Seidel

Publication number: 20240111872Abstract: A method for initializing an engine control system of an aircraft may include authenticating a boot loader, authenticating a manifest in response to authentication of the boot loader wherein the manifest contains hashes of one or more software components, and in response to authentication of the manifest, loading a first set of software components from among the one or more software components onto a non-transitory computer-readable medium, calculating a hash of each software component of the first set of software components, authenticating the first set of software components by comparing the calculated hash of each software component of the first set of software components to the hash of a corresponding software component in the manifest, and executing the first set of software components in response to authentication of the one or more software components. Devices and systems are also provided for initializing an engine control system of an aircraft.Type: ApplicationFiled: September 30, 2022Publication date: April 4, 2024Applicants: General Electric Company, BAE Systems Controls Inc.Inventors: Jeffrey S.

Patent number: 11934527Abstract: A method is disclosed and includes authenticating a first stage boot loader and authenticating a second stage boot loader in response to authentication of the first stage boot loader. The method also includes executing the second stage boot loader in response to authentication of the second stage boot loader. Executing the second stage boot loader includes loading an operating system, a first set of machine-readable instructions, and first configuration information associated with the first set of machine-readable instructions onto a non-transitory computer-readable medium, wherein the first set of machine-readable instructions and the first configuration information are associated with one or more priority partitions. Executing the second stage boot loader includes authenticating the operating system and the first set of machine-readable instructions.Type: GrantFiled: September 24, 2020Date of Patent: March 19, 2024Assignee: General Electric CompanyInventors: Jeffrey S. Gilton, Matthew B. Pfenninger, Douglas R. Nichols, Mark E Hingsbergen
