Abstract
In a wireless mesh network having multiple network managers, the network managers maintain network security through the use of encryption keys and packet counters. To ensure that each network manager can authenticate communications with any node of the network, the authentication data is replicated in a disjoint manner in all network managers. Advantageously, network reliability is assured by providing redundant managers that can seamlessly maintain network operation even if multiple network managers fail; newly joining managers can obtain full authentication data for the network upon joining; and network throughput is increased by ensuring that any of the multiple managers can authenticate the communications of any network node. The disjoint replication of the authentication data across all network managers is performed with low data-rate manager-to-manager packets propagated through the network. The disjoint security methods and systems can advantageously be used in wireless battery monitoring systems, for example.
