Software dev. kit for latest Google Eddystone open beacon

April 15, 2016 // By Graham Prophet
An open beacon format from Google, Eddystone-EID is designed to protect user privacy and security in sensitive applications by preventing unauthorized access and guarding against various potential types of malicious attack. Wireless connectivity chip maker Nordic Semiconductor has released a software development kit (SDK) for the format.

As the beacon market grows so, says Nordic, does the need to protect user privacy and security. Google has announced a more secure version of its Eddystone beacon format - Eddystone-EID - and Nordic Semiconductor (Oslo, norway) announced that it has launched a full software development kit (SDK) plus supporting tools.


Like Eddystone, Eddystone-EID is capable of working across Android and iOS devices but is now designed to protect user privacy and security in sensitive applications by broadcasting secure beacon signals, including website address URLs, using what's termed a 'rotating ephemeral identifier'. This will allow Eddystone-EID beacon manufacturers to manage access to beacons to avoid unpermitted access, and guard against various potential types of malicious attack to which beacons can be prone including spoofing, malicious asset tracking, and replay attacks.


The Nordic Semiconductor 'nRF5 SDK for Eddystone' allows the immediate development of Eddystone-EID beacons to provide real-world context to users in proximity-based beacon applications. The Nordic nRF5 SDK for Eddystone also features a GATT configuration that allows Eddystone beacons to be configured from a smartphone.


The SDK is designed for Nordic's latest nRF52832 / nRF52 Series Bluetooth Smart Systems-on-Chips (SoCs). A future upgrade will also allow existing Nordic nRF51 Series or nRF52832-based Eddystone beacons to be updated to the latest Eddystone-EID secure capabilities via a straightforward over-the-air firmware update.


"Beacons are a core building block of the Internet of Things and the wider trend towards making everyday objects smart," comments Nordic Semiconductor Technical Product Manager, Reidar Martin Svendsen. "Security and privacy has been a concern with today's beacon formats. The new Eddystone-EID opens up new possibilities to use beacons in sensitive applications where the data obtained could be used maliciously.


"In addition, the new ability of the Eddystone beacon format to broadcast URLs opens up endless opportunities. A simple example would be giving advertising posters the ability to broadcast a relevant web address to smartphones
