Abstract
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.
Claims26
A method comprising:
- accessing, at a first computing device, a first key associated with a service;
- generating, based on an identifier for a product class that comprises the first computing device, and based on at least one portion of the first key, a second key unique to the first computing device relative to other computing devices within the product class, wherein the second key is associated with the product class and the service;
- and
- causing, based on the second key, the service to be activated at the first computing device.
A method comprising:
- determining, based on a product class, one or more keys associated with activation of a service at a first computing device, wherein the product class comprises the first computing device;
- and
- sending, to the first computing device, the one or more keys for activation of the service at the first computing device, wherein an identifier for the product class and a root key are stored at the first computing device, wherein the first computing device activates the service based on the one or more keys and a first key generated by the first computing device based on the root key and the identifier for the product class, and wherein the first key is unique to the first computing device relative to other computing devices within the product class.
A method comprising:
- sending, by a first computing device, a request associated with activation of a service at the first computing device, wherein the first computing device is associated with a product class;
- generating, based on at least one portion of a first key associated with the service, and based on an identifier for the product class, a second key unique to the first computing device relative to other computing devices within the product class, wherein the second key is associated with the product class and the service;
- and
- causing, based on the second key, the service to be activated at the first computing device.
