Abstract
A method for authenticating an origin of a network device. The method includes reading one or more encrypted parameters from a memory of the network device, decoding the one or more encrypted parameters, and determining whether one or more of the decoded parameters match parameters obtained from a trusted platform module (TPM) installed in the network device and/or a read only memory (ROM) of the network device. In response to a mismatch between the decoded parameters and the parameters obtained from the TPM or the ROM, at least one of suspending operation of the device or transmitting a report of an authentication failure across a network on which the device is operating.
