This is the first book on secure quantum network coding, which integrates quantum cryptography into quantum communication. It summarizes the main research findings on quantum network coding, while also systematically introducing readers to secure quantum network coding schemes. With regard to coding methods, coding models and coding security, the book subsequently provides a series of quantum network coding schemes based on the integration of quantum cryptography into quantum communication. Furthermore, it describes the general security analysis method for quantum cryptographic protocols. Accordingly, the book equips readers with effective tools for researching and applying quantum network coding.

This book summarizes the main research results and preliminaries of quantum obfuscation and systematically introduces quantum obfuscation methods. Quantum obfuscation is an important and cross-cutting research topic in quantum cryptography and quantum computation. Quantum cryptography and quantum computation have made great progress in this century. However, academic research on the theory of quantum obfuscation is still at a blank stage. The author combines the theory of quantum computation and obfuscation and develop the theory of quantum obfuscation. Until now, a series of representative schemes have been proposed. From the viewpoint of quantum nonlinear function obfuscation, the author designs a series of quantum obfuscation schemes by means of combining obfuscation theory with quantum computation. Furthermore, the author describes the quantum cryptographic protocols based on quantum obfuscation. These methods will provide effective tools for the research and application of quantum cryptography.
