Design of a Secure Disaster Notification System Using the Smartphone Based Beacon

Abstract

The number of disaster occurrences around the world based on the climate changes due to the global warming has been indicating an increase. To prevent and cope with such disaster, a number of researches have been actively conducted to combine the user location service as well as the sensor network technology into the expanded IoT to detect the disaster at early stages. However, due to the appearance of the new technologies, the scope of the security threat to the pre-existing system has been expanding. In this thesis, the D-SASS using the beacon to provide the notification service to the disaster-involved region and the safe service to the users is proposed. The LEA Algorithm is applied to the proposed system to design the beacon protocol collected from the smartphone to safely receive the notification information as well as to provide the confidentiality during the data transfer between smartphone and notification server.

A Dynamic Light-Weight Symmetric Encryption Algorithm for Secure Data Transmission via BLE Beacons

“…In the past, most studies on beacon security focused on protection of the sender's identity [41][42][43][44][45]. To our knowledge, apart from Google's Eddystone [43] which applies the Advanced Encryption Standard (AES) for data encryption in Eddystone-TLM (for broadcasting telemetry information about the beacon), there is limited or no other work on secured light-weight encryption of data transmitted via BLE beacon.…”
