The present invention provides a Y-00-based method for key negotiation and information transmission integration, comprising: the first communication terminal generates a negotiation information sequence and an encryption base sequence; the first communication terminal performs the negotiation information sequence and the encryption base sequence The first process is to obtain the encrypted negotiation information sequence, and send the encrypted negotiation information sequence; the second communication terminal receives the encrypted negotiation information sequence, and generates a decryption base sequence and a key sequence; the second communication terminal obtains the decryption negotiation information sequence ; The second communication terminal obtains the key negotiation information sequence and sends the key negotiation information sequence; the first communication terminal receives the key negotiation information sequence and obtains the key; Three processing, and sending the information sequence that has undergone the third processing; the second communication terminal receives the information sequence that has undergone the third processing, and decrypts the information that has undergone the third processing by decrypting the base sequence to obtain the information that needs to be transmitted sequence.
Description
technical field [0001] The invention relates to the technical field of safe optical communication, in particular to a method for key negotiation and information transmission integration based on the Y-00 protocol. Background technique [0002] With the rapid development of information technology, optical network provides a good transmission platform for blowout information flow. As the foundation of network operation, optical fiber communication has been applied in various aspects of Ethernet system, telecommunications backbone infrastructure and military communication system. However, the optical cable transmission distance is long and the line environment is complex. The existing optical communication cannot resist line or node eavesdropping. At present, the use of physical layer security schemes to achieve communication system security has become a new research hotspot and has received extensive attention at home and abroad. Physical layer secure optical communication is...
