Exploiting Logic Locking for a Neural Trojan Attack on Machine Learning Accelerators. (arXiv:2304.06017v1 [cs.CR])

Logic locking has been proposed to safeguard intellectual property (IP)
during chip fabrication. Logic locking techniques protect hardware IP by making
a subset of combinational modules in a design dependent on a secret key that is
withheld from untrusted parties. If an incorrect secret key is used, a set of
deterministic errors is produced in locked modules, restricting unauthorized
use. A common target for logic locking is neural accelerators, especially as
machine-learning-as-a-service becomes more prevalent. In this work, we explore …
