The neXtECU, is a viable drop-in replacement controller option for control units. The advantages of the neXtECU are not only that it can be implemented on multiple vehicle platforms, but that it will also provide protection for the data it sends and stores. It is essential to adapt and implement cybersecurity protocols into the neXtECU for Army ground vehicles because of the exponential growth of technology and an increased rate of cyber-attacks by U.S. adversaries both foreign and domestic. Currently fielded engine controllers have limited to no cybersecurity protection which leaves them open for Malware, phishing, and possibly clandestine equipment. AT MSU we are helping to test the controllers.
