Abstract

Methods and systems for secure transmission of time synchronization packets by a master node (102) in a network environment (100) are described. The method includes generating, by a processor (108), a time packet marking of a predetermined bit size. The method further comprises encrypting, by the processor (108), the time packet marking using a lightweight encryption technique to generate a master signature. Further, the method comprises appending, by the processor (108), the master signature to an encrypted time synchronization packet generated by the master node (102) to obtain an extended encrypted packet, where the encrypted time synchronization packet includes a transmittal timestamp for time synchronization. The method further comprises transmitting, by the master node (102), the extended encrypted packet to a slave node (104) in the network environment (100) for time synchronization.
