Researchers at Clemson University have received $1 million from the U.S. National Science Foundation to fortify computers and devices against cyberattacks associated with timekeeping.
The team says they will focus on global-positioning system (GPS) spoofing and attacks on Network Time Protocol (NTP).
"We want to provide secure timing solutions, by securing the two most commonly used time distribution approaches," says Clemson professor Yongqiang Wang.
The researchers will study how to counteract GPS spoofing by setting up a server at the university; every 10 seconds, two GPS receivers will sample secret code embedded in signals and upload them to the server, and users across the U.S. will be able to access those samples to verify the signals they are receiving came from the genuine satellite source.
The researchers also will combat NTP attacks by creating a complement to NTP, pulse synch protocol, as a secure way of cross-checking whether computers are closely synchronized under NTP.
