The embodiments described herein describe technologies for Module management, including Module creation and Module deployment 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 create a Module and executes a Module Template to generate the Module in response to the first command. The RA device receives a second command to create a deployment authorization message. The Module and the deployment authorization message are deployed to an Appliance device. A set of instructions of the Module, when permitted by the deployment authorization message and executed by the Appliance device, results in a secure construction of a sequence of operations to securely provision a data asset to the target device.

Securely provisioning a target device

Modules to securely provision an asset to a target device

Trust between entities participating in an upgrade or enablement/disablement process is established and, to facilitate this remotely and securely, a highly tamper resistant point of trust in the system that is being produced is used. This point of trust enables a more efficient distribution system to be used. Through either a provisioning process or at later stages, i.e. subsequent to installation, manufacture, assembly, sale, etc.; the point of trust embodied as a feature controller on the device or system being modified is given a feature set (or updated feature set) that, when validated, is used to enable or disable entire features or to activate portions of the feature.

System and method for controlling features on a device

The embodiments described herein describe technologies for Module management, including Module creation and Module deployment 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 command to create a Module and executes a Module Template to generate the Module in response to the command. The Module is deployed to an Appliance device. A set of instructions of the Module, when executed by the Appliance device, results in a secure construction of a sequence of operations to securely provision a data asset to the target device. The Appliance device is configured to distribute the data asset to a cryptographic manager (CM) core of the target device.

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.

Generating and distributing pre-computed data (PCD) assets to a target device

A system and method for controlling a production process for producing a product is provided in which overproduction may be inhibited by introducing a separation of duties within a production process. Typically a producer will contract out the various stages of a production process to multiple contractors. In general, separation of duties involves purposefully separating production stages, for silicon chips or other products, so that the end product has been handled or 'touched', by each subcontractor, in order for the end product to be fully functional.

System and method for product registration

An asset management system is provided, which includes a hardware module operating as an asset control core. The asset control core generally includes a small hardware core embedded in a target system on chip that establishes a hardware-based point of trust on the silicon die. The asset control core can be used as a root of trust on a consumer device by having features that make it difficult to tamper with. The asset control core is able to generate a unique identifier for one device and participate in the tracking and provisioning of the device through a secure communication channel with an appliance. The appliance generally includes a secure module that caches and distributes provisioning data to one of many agents that connect to the asset control core, e.g. on a manufacturing line or in an after-market programming session.

System and method for hardware based security

The embodiments described herein describe technologies for ticketing systems used in consumption and provisioning of data assets, such as a pre-computed (PCD) asset. A ticket may be a digital file or data that enables enforcement of usage count limits and uniqueness issuance ore sequential issuance of target device parameters. On implementation includes an Appliance device of a cryptographic manager (CM) system that receives a Module and a ticket over a network from a Service device. The Module is an application that securely provisions a data asset to a target device in an operation phase of a manufacturing lifecycle of the target device. The ticket is digital data that grants permission to the Appliance device to execute the Module. The Appliance device verifies the ticket to execute the Module. The Module, when executed, results in a secure construction of a sequence of operations to securely provision the data asset to the target device.

Auditing and permission provisioning mechanisms in a distributed secure asset-management infrastructure

The embodiments described herein describe technologies for a device definition process to establish a unique identity and a root of trust of a cryptographic manager (CM) device, the CM device to be deployed in a CM system. The device definition process can take place in a device definition phase of a manufacturing lifecycle of the CM device. One implementation includes a non-transitory storage medium to store an initialization application that, when executed by a CM device, causes the CM device to perform a device definition process to generate a device definition request to establish the unique identity and the root of trust. In response to the device definition request, the initialization application obtains device identity and device credentials of the CM device and stores the device definition request in storage space of a removable storage device. The initialization application imports a device definition response containing provisioning information generated by a provisioning device of a cryptographic manager system in response to the device definition request.

Establishing an initial root of trust for individual components of a distributed security infrastructure

Techniques for use in transferring an assignment of a secure chip of a wireless device from a current subscription manager (SM) of a current mobile network operator (MNO) to a new SM of a new MNO are described. In one illustrative example, the current SM receives a request for transferring the assignment and produces transfer permission data in response. The transfer permission data includes an identifier of the secure chip, an identifier of the current SM, and a digital signature of the current SM. The current SM then sends to the secure chip a transfer permission message which includes the transfer permission data. The transfer permission data indicates a permission for the secure chip to transfer the assignment from the current SM to the new SM. Additional techniques are performed by the secure chip, and the new SM, as described.
