Security monitoring for wireless sensor nodes

Abstract

Security monitoring for wireless sensor nodes. Specifically, the method and wireless sensor network disclosed herein entail the retrieval and analysis of log information immutably consolidated in one or more wireless sensor nodes, to detect intrusions (i.e., attacks) on the wireless sensor node(s) by unauthorized entities. The log information in any given wireless sensor node may record events, pertaining to pairing activities, connection activities, and/or data transfer activities, between the given wireless sensor node and other devices (including both authorized devices and unauthorized devices (if any)). Further, upon detection of an intrusion based on the analysis of log information, one or more actions designed to reactively address the intrusion may be performed. Moreover, a proactive approach for preventing the phishing of static passcodes used in the pairing authentication process across Bluetooth and/or Bluetooth Low Energy (BLE) wireless communications is proposed.
