Abstract

Disclosed are physical unclonable functions ('PUFs') that provide both a hardware timestamp and an encryption key. The timestamp is more accurate than traditional timestamps generated by software calls to the computing device's operating system, while the encryption key can be used for, among other things, securing time-synchronization packets sent across a network. By combining timestamp generation with encryption key generation, the PUFs provide enhanced security while being cheaper to build and to operate than the specialized cryptographic hardware that they replace.
