QUANTUM KEY DISTRIBUTION METHOD AND DEVICE, AND STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18166336 titled 'QUANTUM KEY DISTRIBUTION METHOD AND DEVICE, AND STORAGE MEDIUM
Simplified Explanation
The patent application discloses methods and devices for quantum key distribution, as well as storage media.
- An inode generates a third quantum key based on a first quantum key and a second quantum key corresponding to the inode on a target routing path.
- The third quantum key is sent to a destination node on the target routing path, or used to encrypt a received first ciphertext.
- The encrypted second ciphertext is then sent to the next node on the target routing path.
Potential Applications
- Secure communication: The quantum key distribution methods can be used to establish secure communication channels between nodes, ensuring the confidentiality of transmitted data.
- Data storage: The storage media disclosed in the patent application can be used to securely store sensitive information using quantum encryption techniques.
Problems Solved
- Insecure communication: The quantum key distribution methods address the problem of insecure communication channels by using quantum keys that cannot be easily intercepted or decrypted.
- Data breaches: The encryption techniques employed in the patent application help prevent unauthorized access to stored data, reducing the risk of data breaches.
Benefits
- Enhanced security: The use of quantum keys provides a higher level of security compared to traditional encryption methods, making it extremely difficult for attackers to intercept or decipher the transmitted data.
- Data protection: The encryption techniques employed in the patent application ensure the confidentiality and integrity of stored data, protecting it from unauthorized access and tampering.
Original Abstract Submitted
This application discloses quantum key distribution methods and devices, and storage media. In an implementation, an inode generates, based on a determined first quantum key corresponding to the inode on a target routing path and a determined second quantum key corresponding to the inode on the target routing path, a third quantum key corresponding to the inode on the target routing path, and sends the third quantum key corresponding to the inode on the target routing path to a destination node on the target routing path, or encrypts a received first ciphertext by using the third quantum key corresponding to the inode on the target routing path, and sends an obtained second ciphertext corresponding to the inode to an (i+1)node on the target routing path.
