Position Paper: Secure Time Transfer for CPS
Abstract
To secure the future of “new clockwork,” research
must overcome the current vulnerabilities of cyber-physical
systems to malicious timing attacks. Such attacks can take a wide
range of forms—from physical to cyber to a mixture of both—
and can cause a wide range of impacts—from local outages to
system-wide failures. This paper presents four “needs” that, if
properly addressed, will lead to a better understanding of the
impact of malicious timing attacks on today’s CPS and offer a
secure time transfer protocol to defend future CPS from such
threats.
