AI Technical Summary

Technical Problem

In existing technologies, real-time encrypted communication has low security in web applications, and quantum key distribution technology is difficult to adapt to high-concurrency environments, and its deployment cost and complexity are high.

Method used

A quantum chip-based communication encryption method is adopted. By pre-storing the quantum key-identifier mapping relationship, a WebSocket connection is established between the client and the server. A true random quantum key is used for encryption and decryption. Only the identifier is transmitted instead of the key. The key is supplemented by a quantum cryptography service platform and a quantum-resistant channel.

Benefits of technology

It improves the security of real-time encrypted communication, reduces communication overhead, resists quantum computing threats, meets the real-time supply requirements of multiple quantum keys under high concurrency in the Web, and adapts to the low latency and high throughput requirements of WebSocket.

Abstract

The application discloses a quantum chip-based communication encryption method for a client, a quantum chip-based communication encryption method for a server, a client, a server and a quantum chip-based communication encryption system. The method comprises the following steps: determining an unused first target quantum key and a first target identifier corresponding to the first target quantum key based on a quantum key-identifier mapping relationship pre-stored in a first quantum chip of the client; performing encryption processing on first plaintext data to be sent according to the first target quantum key, and determining first ciphertext data; performing encapsulation processing on the first ciphertext data and the first target identifier, and determining a first target data frame; and sending the first target data frame to the server. In this way, the client and the server share the same quantum key-identifier mapping relationship, the real-time supply demand of multiple quantum keys under the high concurrency of Web can be met, and the security of real-time encryption communication is improved.
