Abstract
A metrology device may include a processor and a non-transitory computer-readable media storing instructions that, when executed by the processor, cause the processor to perform operations. The operations may include generating a challenge message, the challenge message including a challenge; issuing the challenge message in a scannable undirected advertising message; receiving from the field tool a response solution to the challenge message, the response solution being calculated based at least in part on the challenge and a challenge key associated with the challenge, and verifying the response solution based at least in part on a secure hash algorithm (SHA). The challenge key may include a fixed value specific to a manufacturer of the metrology device and known to the field tool and the metrology device.
