Google announced a new, more secure version of its Eddystone beacon format – Eddystone-EID – and Nordic Semiconductor simultaneously announced that it has launched a full software development kit (SDK) and tools to support it.
Eddystone-EID is capable of working across Android and iOS devices, and is upgraded to protect user privacy and security in sensitive applications by broadcasting secure beacon signals, including website addresses, 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 is available now and allows the immediate development of Eddystone-EID beacons to provide real-world context to users in a huge variety of proximity-based beacon applications. The SDK 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-Chip (SoCs), while a future upgrade will also allow existing 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.
