Abstract
Methods and systems for secure key generation are provided. In embodiments, during the manufacturing process, a device generates a primary seed for the device and stores the seed within the device. The device exports the device primary key to a secure manufacturer server. The secure manufacturer server generates a public/private root key for the device and requests a certificate for the public root key of the device from a certificate authority. The device, having the stored primary seed, is integrated into an end-user system. Upon occurrence of a condition, the device after integration into the end-user system generates the public/private root key in the field. The system also receives and installs the certificate for the public root key.
