This paper proposes two novel protection schemes for multi-FPGA systems providing high security of IP designs licensed by IP vendors to system integrators and installed remotely in a hostile environment. In the first scheme, these useful properties are achieved by storing two different configuration keys inside an FPGA, while in the second scheme, they are obtained using a hardware white-box cipher for creating a trusted environment. Thanks to the proposed principles, FPGA configurations coming from different IP owners cannot be cloned or reverse-engineered by any involved party, including system integrator and other IP owners. The proposed schemes can be directly implemented in recent FPGAs such as Xilinx Spartan 6 and Virtex 6.
