This project demonstrates enhanced awareness of the "provenance" / origin of data traversing the network from originator to consumer (e.g. sensor to shooter) in the presence of cyber-attacks, ensuring that the data can be trusted, has not been modified or manipulated, and has been authenticated for use in real-time decision making. Work in this project complements Program Element (PE) 0602213A (C3I Applied Cyber) / Project 2CY (Information Trust Technology). Work in this project is performed by the Command, Control, Computers, Communications, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) Center.

Program detail

Mission & acquisition strategy

This Program Element (PE) matures and demonstrates technologies for offensive and defensive cyber operations in tactical environments. Projects optimize devices, techniques, services, software and algorithms to enable cyber situational understanding and Cyber Electromagnetic Activities (CEMA). For offensive cyber, efforts demonstrate integrated electronic attack (EA) and CEMA hardware and software to execute force protection (FP), EA, electronic surveillance (ES), signals intelligence (SIGINT), electronic warfare (EW) and cyber missions in a dynamic, distributed and coordinated fashion.
