FuncTeller: How Well Does eFPGA Hide Functionality?. (arXiv:2306.05532v1 [cs.CR])

Hardware intellectual property (IP) piracy is an emerging threat to the
global supply chain. Correspondingly, various countermeasures aim to protect
hardware IPs, such as logic locking, camouflaging, and split manufacturing.
However, these countermeasures cannot always guarantee IP security. A malicious
attacker can access the layout/netlist of the hardware IP protected by these
countermeasures and further retrieve the design. To eliminate/bypass these
vulnerabilities, a recent approach redacts the design's IP to an embedded
field-programmable gate array (eFPGA), disabling the attacker's access …
