基于PON网络的量子匿名通信机理及安全问题研究

As an important field in qauntum information science, quantum network communication has made a rapid development in recent years. PON network, a critical technology of the access network, has already occupied a large market share. It is also a means of integration of optical networks and quantum communication. In order to solve the security problems in PON network, the quantum anonymous communication becomes a hotspot in quantum communications.This project is planned to investigate the features of integration of quantum anonymous communication with non-maximally entanglement, hyper-entanglement, and hybrid entanglement. It aims to design several quantum anonymous communication schemes based on the principle of quantum entanglement, which solve the security issues of PON network. The contributations of this project are as follows: Firstly, we study the integration of several quantum entanglements, such as non-maximally entanglement, hyper-entanglement and hybrid entanglement, with PON network in order to clarify the machanisms of the quantum anonymous communications. Secondly, we design the corresponding quantum anonymous communication schemes using the non-maximally entanglement, hyper-entanglement, and hybrid entanglement measurements and analyze its security. Finally, we optimize these schemes while we analyze the security and efficiency of the proposed schemes by means of the theoretical and experimental investigations.The reasearch on quantum anonymous communication mechanism and its security issues in PON network not only has theoretical value and scientific significance, but also has an important influence on the design of PON network. It also has a momentous merit in practical deployment of quantum communication network while increasing the secuirty of communications, boosting the capacity of transmissions, and improving the quality of service.
