Abstract
As a new security technology in the physical layer of optical communication, quantum noise stream cipher combines mathematical complexity and physical complexity. The quantum noise stream cipher has the advantages of high security, high speed, long span, flexible structure, and high compatibility with the existing optical fiber communication systems. This paper presents the current research status and the basic principle of the quantum noise stream cipher. In the aspect of key negotiation, we compare the Y-00 protocol of quantum noise stream cipher with the BB84-type protocol of quantum key distribution and summarize the quantum noise stream cipher’s key technical schemes. Additionally, we introduce a typical application of quantum noise stream cipher and propose an endogenously secure optical communication system with a unified negotiation channel and transmission channel. The experimental verification is demonstrated, and finally, the development trend of a quantum noise stream cipher is analyzed.
