A secure programming system and method for provisioning and programming a target payload into a programmable device mounted in a programmer. The programmable device can be authenticated before programming to verify the device is a valid device produced by a silicon vendor. The authentication process can include a challenge-response validation. The target payload can be programmed into the programmable device and linked with an authorized manufacturer. The programmable device can be verified after programming the target payload by verifying the silicon vendor and the authorized manufacturer. The secure programming system can provision different content into different programmable devices simultaneously to create multiple final device types in a single pass.

Device programming with system generation

A secure programming system can receive a job control package having a security kernel and a target payload of content for programming into a pre-defined set of trusted devices. A device programmer can install a security kernel on the trusted devices and reboot the trusted devices using the security kernel to validate the proper operation of the security kernel. The target payload can then be securely installed on the trusted devices and validated.

Unified programming environment for programmable devices

A device identification is generated for a programmable device. A security key is generated to protect a content of the programmable device. A device birth certificate is generated with the device identification and the security key. The programmable device is programmed with the device birth certificate at time of manufacture of the programmable device.

Device birth certificate

A secure programming system and method for provisioning and programming a target payload into a programmable device mounted in a programmer. The programmable device can be authenticated before programming to verify the device is a valid device produced by a silicon vendor. The target payload can be programmed into the programmable device and linked with an authorized manufacturer. The programmable device can be verified after programming the target payload by verifying the silicon vendor and the authorized manufacturer.

An identification token of a programmable device is determined whether to be invalid. In response to determining that the identification token is invalid, the programmable device is identified as unauthorized. A parameter associated with the unauthorized programmable device is reported to a programming unit.

Counterfeit prevention

Approaches, techniques, and mechanisms are disclosed for provisioning programmable devices in a secure manner. The secure programming system can individually encrypt a target payload of data and code and then program the information into each individual one of the programmable devices targeted for a specific job. The secure programming system can create a customized payload package that can only be decrypted by a particular system or device having the correct security keys.
