In this paper, we claim that cyclic obfuscation, when properly implemented, poses
exponential complexity on SAT or CycSAT attack. The CycSAT, in order to generate the …

State-of-the-art attacks against cyclic logic obfuscation use satisfiability solvers that are
equipped with a set of cycle-avoidance clauses. These cycle-avoidance clauses are …

LOOPLock is the state-of-the-art cyclic logic locking method in hardware security. LOOPLock
is able to invalidate SAT Attack, Removal Attack, and CycSAT simultaneously by introducing …

SAT Attack, CycSAT, and Removal Attack have demonstrated their abilities to break most
existing logic locking methods. In this article, we propose a new cyclic logic locking method …

Existing logic-locking attacks are known to successfully decrypt functionally correct key of a
locked combinational circuit. It is possible to extend these attacks to real-world Silicon-based …

Cyclic logic locking is a new type of SAT-resistant techniques in hardware security. Recently,
LOOPLock 2.0 was proposed, which is a cyclic logic locking method creating cycles …

Cyclic logic locking is a cutting-edge hardware security method developed to defend against
SAT Attack. It introduces cycles into the original circuit, which can cause the circuit to either …

反馈环路是模拟电路中有效容错的电路结构. 反馈电路也因其存储性能而被广泛使用于数字电路
的时序电路中, 但是反馈电路在数字电路的组合电路的稳定特性鲜少被人研究 …

Programmable logic devices on base of asynchronous combinational circuits with feedback
are considered. The main aim of the research is to obtain a method for designing a circuit …

The increasing cost of building, operating, managing, and maintaining state-of-the-art silicon
manufacturing facilities has pushed several stages of the semiconductor device's …
