    Current IP encryption methods offered by FPGA vendors use an approach where the IP is decrypted during the CAD flow, and remains unencrypted in the bitstream. Given the ease of accessing modern bitstream-to-netlist tools, encrypted IP is vulnerable to inspection and theft from the IP user. While the entire bitstream can be encrypted, this is done by the user, and is not a mechanism to protect confidentiality of 3rd party IP. In this work we present a design methodology, along with a proof-of-concept tool, that demonstrates how IP can remain partially encrypted through the CAD flow and into the bitstream. We show how this approach can support multiple encryption keys from different vendors, and can be deployed using existing CAD tools and FPGA families. Our results document the benefits and costs of using such an approach to provide much greater protection for 3rd party IP.
