==SECURE RELAY-BASED QUANTUM COMMUNICATION METHOD AND COMMUNICATION NETWORK - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240048371 titled 'SECURE RELAY-BASED QUANTUM COMMUNICATION METHOD AND COMMUNICATION NETWORK

==Simplified Explanation==

The present application describes a secure repeater-based quantum communication method and network. The method involves encrypting plaintext information into ciphertext using a transmitter. The ciphertext is then sent to a repeater node through a quantum communication protocol, which allows the ciphertext to be transmitted to a receiver through one or more repeater nodes. Upon receiving the ciphertext, the receiver decrypts it to obtain the original plaintext information. The ciphertext is transmitted step by step through the repeater nodes, enabling long-distance transmission. Additionally, the plaintext information is transmitted in the form of ciphertext and decrypted on the fly before reaching the receiver, reducing the risk of eavesdropping and enhancing security.

* Transmitter encrypts plaintext information to obtain ciphertext.
* Ciphertext is sent to a repeater node using a quantum communication protocol.
* Ciphertext is transmitted through one or more repeater nodes to reach the receiver.
* Receiver decrypts the ciphertext to obtain the original plaintext information.
* Repeater nodes enable long-distance transmission of the ciphertext.
* On-the-fly decryption of the ciphertext reduces the risk of eavesdropping.

Potential Applications:
* Secure communication in sensitive industries such as defense, finance, and healthcare.
* Quantum key distribution for secure encryption of data.
* Quantum secure direct communication for confidential messaging.

Problems Solved:
* Mitigates the risk of information being eavesdropped during transmission.
* Enables long-distance transmission of encrypted data.
* Enhances the security of quantum communication networks.

Benefits:
* Improved security and confidentiality of transmitted information.
* Facilitates secure communication over long distances.
* Reduces the vulnerability of quantum communication networks to eavesdropping.


==Original Abstract Submitted==

the present application provides a secure repeater-based quantum communication method and communication network. said method comprises a transmitter encrypting plaintext information to be sent, to obtain ciphertext; the transmitter sending the ciphertext to a repeater node by means of a quantum communication protocol, so as to send the ciphertext to a receiver by means of at least one repeater node; and after receiving the ciphertext, the receiver decrypting the ciphertext to obtain the plaintext information. the ciphertext is transmitted step by step by means of the at least one repeater node, which is not limited to the distance between the transmitter and the receiver, so that the ciphertext can be transmitted over a long distance. furthermore, before arriving at the receiver, the plaintext information is transmitted in the form of a ciphertext and is decrypted on the fly, thereby reducing the risk of information being eavesdropped, improving the security.
