量子混淆研究综述

With the rapid advancement of quantum computing, the complexity and scale of quantum circuits are steadily increasing. What was once deemed an unreachable goal, the protection of information within quantum circuits, is now gradually becoming a tangible threat. As a derivative of classical obfuscation theory, quantum obfuscation theory combines classical obfuscation and quantum computing. Serving as a potent tool for safeguarding information in quantum circuits within the quantum environment, quantum obfuscation has garnered significant attention and witnessed rapid growth in recent years. Quantum obfuscation can conceal the information of quantum circuits without altering their functionality, thus realizing function preservation. It proves effective against reverse engineering attacks and offers solutions to secure outsourced computing and copyright protection issues in the quantum environment. Considering the significance of quantum obfuscation theory and its applications, this study commences by elucidating the definition and current research status of classical obfuscation. Subsequently, the study systematically summarizes the definition, model, and security aspects of quantum obfuscation, along with analyzing its realizable quantum cryptography primitives and application schemes. Finally, this study summarizes the challenges faced by quantum obfuscation theory and points out the future research directions and application scenarios.
