Abstract:
This memo describes the Autokey security model for authenticating servers
to clients using the Network Time Protocol (NTP) and public key cryptography. Its design is
based on the premise that IPsec schemes cannot be adopted intact, since that would
preclude stateless servers and severely compromise timekeeping accuracy. In
addition, Public Key Infrastructure (PKI) schemes presume authenticated time values are always
available to enforce certificate lifetimes; however, cryptographically verified timestamps
require interaction between the timekeeping and authentication functions.
