Patents by Inventor Shuting XIAO

Shuting XIAO has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cryptographic operation method, working key creation method, cryptographic service platform, and cryptographic service device
    Patent number: 11128447
    Abstract: A cryptographic service device includes: a processor; and a memory storing instructions executable by the processor, wherein the processor is configured to execute the instructions to operate as a registration module, a working key creation module, and a cryptographic operation calling module. The registration module is configured to call a primary security module to generate a master key for a newly added secondary security module. The working key creation module is configured to receive a working key creation request of a business system, call the primary security module to generate a working key for the business system, and acquire a working key ciphertext. The cryptographic operation calling module is configured to receive a cryptographic operation request of the business system; call a target security module, and obtain an operation result of the target security module.
    Type: Grant

  • Cryptographic operation method, method for creating working key, cryptographic service platform, and cryptographic service device
    Patent number: 11025415
    Abstract: A cryptographic service device includes: a processor; and a memory storing instructions executable by the processor, wherein the processor is configured to execute the instructions to operate as a registration module, a working key creation module, and a cryptographic operation calling module. The registration module is configured to call a secondary security module to generate an asymmetric key pair including a target public key and a target private key. The working key creation module is configured to receive a working key creation request of a business system, and call a primary security module to generate a working key for the business system. The cryptographic operation calling module is configured to receive a cryptographic operation request of the business system, and call a target security module to obtain an operation result of the target security module.
