Beacons are small-sized embedded devices that periodically broadcasts radio frequency (RF) signals without establishing a connection so that any other Bluetooth-equipped device/s in the range can receive the broadcasted data, but some applications desired that data should be observed only by an authenticated receiver. The beacon specification does not have any authentication mechanism, anyone can observe broadcasted information. Beacon has very limited security provisions, as any observer can receive the signal and also easily get the message. This research defined an extension of Google Eddystone-UID for secured data broadcasting without affecting regular operations. The proposed “Extended Eddystone-UID Frame” assures secured broadcasting by performing the data cryptography and data integrity. The experiment concluded that the proposed frame does not add any extra bytes, therefore, it does not require any more time and energy, and it is capable to broadcast data securely at the same time and energy as standard protocol required.
