Recently, eFPGA-based redaction has been proposed as a promising solution for hiding parts of a digital design from untrusted entities, where legitimate end-users can restore functionality by loading the withheld bitstream after fabrication. However, when deciding which parts of a design to redact, there are a number of practical issues that designers need to consider, including area and timing overheads, as well as security factors. Adapting an open-source FPGA fabric generation flow, we perform a case study to explore the trade-offs when redacting different modules of open-source intellectual property blocks (IPs) and explore how different parts of an eFPGA contribute to the security. We provide new insights into the feasibility and challenges of using eFPGA-based redaction as a security solution.

Abstract

Recently, eFPGA-based redaction has been proposed as a promising solution for hiding parts of a digital design from untrusted entities, where legitimate end-users can restore functionality by loading the withheld bitstream after fabrication. However, when deciding which parts of a design to redact, there are a number of practical issues that designers need to consider, including area and timing overheads, as well as security factors. Adapting an open-source FPGA fabric generation flow, we perform a case study to explore the trade-offs when redacting different modules of open-source intellectual property blocks (IPs) and explore how different parts of an eFPGA contribute to the security. We provide new insights into the feasibility and challenges of using eFPGA-based redaction as a security solution.
