One of the world’s largest manufacturers of aviation, military and space technology, Boeing, announced that the patented new development, the essence of which is to protect the GPS receivers using the blockchain from tampering.
In an accompanying note to the patent, published on the website of the office of patents and trademarks USA, said the development is an onboard system for backup and protection against spoofing.
GPS spoofing allows you to “confuse” the transmitter by feeding him false signals. It is used to confuse sensors, distorting the data about the location of certain objects, whose coordinates are initially set correctly.
“In the backup will be stored reliable information received from the GPS, so the system becomes fault tolerant and will apply to all types of vehicles, including unmanned”, — reported in the explanatory note to the patent.
Thus, applying the blockchain technology to protect on-Board systems, Boeing expects to protect its equipment against false signals. If necessary, the backup data will be back again if the protection system detects spoofing attempts of coordinates.
