Sharon Goldberg Finds Flaw in Computers’ Timekeeping

Working with students Aanchal Malhotra (GRS’19), Isaac Cohen (CAS’16), and Erik Brakke (CAS’16) last spring, Goldberg discovered a potential vulnerability in the Network Time Protocol (NTP), the software and rules that synchronize clocks on computers.

Other apps, from bitcoin systems to website authentication and login protocols, also could be breached.

“If NTP breaks, many other computing applications break as well,” says Goldberg.
