ABSTRACT:
A system and method are described for securing a configurable system on a chip (CSoC) or other programmable chip design to prevent unauthorized copying. A processor reads instructions from a memory device. The processor reads an identification code from an identification code provider. If no identification code has been previously imprinted on the memory, the processor imprints the provider identification code into the memory. If an identification code is already present, the memory identification code is compared with the provider identification code. If the memory identification code matches with the provider identification code, the processor is allowed to perform the program present on the memory. If the memory identification code does not match with the provider identification code, appropriate security countermeasures are taken. The program and identification code can be further encrypted on the memory for greater security, using the provider identification code as the encryption key.
