New Research Identifies Major TTE Network Vulnerability

A new attack discovered by the University of Michigan and NASA exploits a trusted network technology to create unexpected and potentially catastrophic behavior. The technology — time-triggered ethernet (TTE) — is widely used in critical infrastructures such as spacecraft, aircraft, energy-generation systems, and industrial control systems.

“We wanted to determine what the impact would be in a real system,” said Baris Kasikci , the Morris Wellman Faculty Development Assistant Professor of Computer Science and Engineering. “If someone executed this attack in a real spaceflight mission, what would the damage be?”
