Abstract
Methods, circuits, and apparatus are provided an FPGA user, ASIC designer, or the like the ability to program a unique ID per each circuit into a memory, such as a non-volatile one-time programmable memory bank on an FPGA. This unique ID is secure such that no one else can replicate it on another part, thus keeping it unique to the user for which it was intended. An encryption engine receives plaintext and produces the unique ID that is stored in memory that is designed to only be writeable through the encryption engine. Thus, the FPGA/ASIC designer can track who is the customer they sold this part to or who the last authorized user is.
