Ci-Lock: Cipher Induced Logic Locking Resistant Against SAT Attacks
Logic locking Block cipher Hardware obfuscation
2019/8/30
Protection of intellectual property (IP) cores is one of the most practical security concern for modern integrated circuit (IC) industry. Albeit being well-studied from a practical perspective, the pr...
The End of Logic Locking? A Critical View on the Security of Logic Locking
Logic Locking Logic Encryption
2019/7/15
With continuously shrinking feature sizes of integrated circuits, the vast majority of semiconductor companies have become fabless, i.e., chip manufacturing has been outsourced to foundries across the...
The Key is Left under the Mat: On the Inappropriate Security Assumption of Logic Locking Schemes
Logic Locking Optical Contactless Probing Tamper-proof Memory
2019/6/19
Logic locking has been proposed as an obfuscation technique to protect outsourced IC designs from Intellectual Property (IP) piracy by untrusted entities in the design and fabrication process. It obfu...
Vulnerability and Remedy of Stripped Function Logic Locking
Logic Locking SAT-based Attack Stripped Function Logic Locking
2019/2/26
Stripped Function Logic Locking (SFLL) as the most advanced logic locking technique is robust against both the SAT-based and the removal attacks under the assumption of thorough resynthesis of the str...
Secure and Effective Logic Locking for Machine Learning Applications
Logic Locking SAT Attack Machine Learning Applications
2019/1/9
Logic locking has been proposed as a strong protection of intellectual property (IP) against security threats in the IC supply chain especially when the fabrication facility is untrusted. Various tech...
This paper proposes Functional Analysis attacks on state of the art Logic Locking algorithms (abbreviated as FALL attacks). FALL attacks have two stages. The first stage identifies nodes involved in t...
Logic locking is a technique that's proposed to protect outsourced IC designs from piracy and counterfeiting by untrusted foundries. A locked IC preserves the correct functionality only when a correct...
