Research and Application of Encryption System Based on Quantum Circuit for Mobile Internet Security

Information technology is developing rapidly, which not only brings opportunities to the society, but also causes various problems of mobile internet information security. Quantum circuits have many characteristics, such as high-complexity and no feedback. This paper applies quantum circuits to the field of encryption technology. A quantum circuit encryption system is designed based on AES. The system uses quantum circuits to construct the encryption algorithm and realizes the mathematical operations and transformation in quantum logic which can be realized through quantum logic gates. Encryption system of quantum circuits can improve the encryption complexity. Its anti-attack ability is (2^n-1)! times of the traditional method, thus it can effectively protect the information security of the IoT. In order to increase the practicability of the system, an interface module is also designed to facilitate the interaction of the system with the outside world. Finally, the encryption rate, resource utilization, and encryption effect of the quantum circuit encryption system are tested, which shows the advantages of it.
