Abstract
A method for key refreshment in a wireless network system using a salt. The method includes receiving, from each of a plurality of secondary nodes communicably coupled to a primary node, a current session number. The current session numbers are compared to a session number at the primary node to identify a mismatch, and a salt is generated responsive to identifying the mismatch. The method further includes sending the salt to each of the plurality of secondary nodes having a current session number matching the session number at the primary node.
