IP protection usage flow IP protection is initiated when the OEM provides the SBSL ID of the target devices to the IDH. Once the SBSL ID of the target devices is known, the IDH encrypts the IP using Over 5000 Std.

If more than one SBSL ID is used, there will be a corresponding number of output files generated, one for each SBSL ID. The Programmer House then uses the programming tool to download the encrypted data through the Secure Loader into the target device, where it will be decrypted and programmed into the Flash memory. The Programmer House must use devices that have a SBSL ID matching to the list provided by the OEM, otherwise the programming tool will flag an error and data download to the unknown device fails. The programmed devices are finally shipped to the OEM for end product assembly. The discussion in this article references a market model involving an OEM, an IDH and a Programmer House, but the IP protection scheme can be easily applied to other models as well.
