Abstract
The embodiments described herein describe technologies for pre-computed data (PCD) asset generation and secure deployment of the PCD asset to a target device in an operation phase of a manufacturing lifecycle of the target device in a cryptographic manager (CM) environment. One implementation includes a Root Authority (RA) device that receives a first command to generate a unique PCD asset for a target device. In response, the RA device generates the PCD asset and packages the PCD asset for secure deployment of the PCD asset to the target device and to be used exclusively by the target device. The RA device deploys the packaged PCD asset in a CM system for identification and tracking of the target device.
