Abstract
Systems, methods and devices for adding key chain and key derivative functions (KDF) support for Network time protocol (NTP) authentication using password based key derivation functions-NTP (PBKDF-NTP) are disclosed. In one embodiment, a method includes generating time bound multiple short lived keys instead of long lived keys for NTP security which ensures that attacker will not get enough time to crack the key values. The usage of time bound multiple short lived keys instead of long lived keys for NTP security will ensure that attacker will not get enough time to crack the key values within key lifetime. Hence man-in-middle attack can be avoided in NTP.
