Abstract: Aspects may relate to a device that comprises: a non-volatile storage medium (NVM) to store a signature and a device key, the device key based on a symmetric master key and an identifier; an interface; and a processor coupled to the interface and the NVM. The processor may be configured to: apply a key derivation function (KDF) to the device key to generate a derivative key; apply a key generation function to the derivative key to generate at least one public key; and command transmission of the signature and the at least one public key through the interface to a service provider.
