Shared FPGAs and the Holy Grail: Protections against Side-Channel and Fault Attacks

2021
Conference Papers

Abstract

In this paper, we survey recently proposed methods for protecting against side-channel and fault attacks in shared FPGAs. These methods are quite versatile, targeting FPGA compilation flow, real-time timing-fault detection, on-chip active fences, automated bitstream verification, etc. Despite their versatility, they are mostly designed to counteract a specific class of attacks. To understand how to address the problem of security in shared FPGAs in a comprehensive way, we discuss their individual strengths and weaknesses, in an attempt to identify research directions necessitating further investigation.

Logic synthesis

In computer engineering, logic synthesis is a process by which an abstract specification of desired circuit behavior, typically at register transfer level (RTL), is turned into a design implementation in terms of logic gates, typically by a computer program called a synthesis tool. Common examples of this process include synthesis of designs specified in hardware description languages, including VHDL and Verilog. Some synthesis tools generate bitstreams for programmable logic devices such as PALs or FPGAs, while others target the creation of ASICs.

Field-programmable gate array

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured after manufacturing. The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC). Circuit diagrams were previously used to specify the configuration, but this is increasingly rare due to the advent of electronic design automation tools. FPGAs contain an array of programmable logic blocks, and a hierarchy of reconfigurable interconnects allowing blocks to be wired together.

High-level synthesis

High-level synthesis (HLS), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior. Synthesis begins with a high-level specification of the problem, where behavior is generally decoupled from low-level circuit mechanics such as clock-level timing.
