Abstract
A patient care environment includes a monitoring device and a vital sign device, where the vital sign device communicates patient vital sign data to the monitoring device. A site key, entity keys, and key combining algorithms are used to secure communications in the patient care environment. Neither the site key nor the entity keys are communicated between the monitoring device and the vital sign device. The monitoring device may use the site key and entity keys to decrypt encrypted messages that have been previously stored in the vital sign device and transmitted back to any monitoring device containing the correct set of site and entity keys. The site key and entity key may also be used during the discovery and/or connection operations between the monitoring device and the vital sign device to associate a wirelessly connected vital sign device with a patient record.
