Abstract:<p>The obfuscation of a combinational logic circuit using logic locking is similar to symmetric cryptography and can be expressed in terms of a quantified Boolean function. Satisfiability checking algorithms are used to reveal the secret key of the logic locking (so-called SAT attacks). In this paper, we analyze the impact of quantum computers for these SAT-based attacks similar to the impact on symmetric cryptographic ciphers. For the first time to our knowledge, we propose modifications of existing log… Show more
