US Patent 11888989 Methods and systems for key generation

Methods and systems for key generation and device management are disclosed. A root key can be stored on a component which can be integrated with a device, and the component can store a product class identifier. The product class identifier can define a class of products, devices, features, hardware components, or other entities. One or more keys can be generated and stored on the devices based on the product class identifier and the root key. A network operator or service provider can then provide services to a class of devices that includes the device, or perform and manage other functions. The services can be authorized or otherwise implemented based on the one or more new keys stored at the devices within the class of devices.
