1. A method comprising:

  • receiving, by an Appliance device at a first facility, a Module over a network from a Service device at a second facility, different from the first facility, wherein the Module is a first application that, when executed by the Appliance device, securely provisions a data asset to a target device in an operation phase of a manufacturing lifecycle of the target device;

    receiving, by the Appliance device, a communication from a cryptographic manager (CM) client library of a tester device, wherein the communication comprises an argument from the CM client library;

    in response to the communication, invoking the Module by the Appliance device to generate a Module sequence based on the argument; and

    sending, by the Appliance device, the Module sequence to the CM client library, wherein a tester script of the tester device delivers the Module sequence to a CM Core of the target device to securely provision the data asset to the target device in the operation phase of the manufacturing lifecycle of the target device, wherein the target device is a monolithic integrated circuit that is not part of the Appliance device, wherein the CM core is configured to execute a set of commands to provide cryptographic control of the data asset when the target device is deployed in a product, wherein the set of commands to provide cryptographic control comprises at least one of feature activation of one or more features of the target device, configuration management of the target device, or secure key management of the target device.
