Patent 12130910 was granted and assigned to ICU Medical on October, 2024 by the United States Patent and Trademark Office.
The present disclosure is directed to managing device authorization through the use of digital signature thresholds. Individual components of a device, or individual devices in a network environment, are associated with separate secret shares from which a digital signature can be derived. The digital signature may be used to authorize performance of a function. A threshold number of such secret shares are used in order to derive the digital signature. Therefore, an authorization process that relies on digital signature verification to determine that a function is authorized will do so if a threshold number of secret shares are available at authorization time.
