Latest Patents

Xie is named on 1 patent: “Quantum Key Transmission Method, Apparatus, and System.” The invention describes a process in which an application device sends a key request packet containing a user identifier, a public key, and a message authentication code to a quantum device. After verifying the code, the quantum device returns a response containing ciphertext and another authentication code. Once that code is verified, the application device uses its corresponding private key to decrypt the ciphertext and obtain the quantum key allocated to it. The public and private keys are generated using a post-quantum key-generation algorithm.
