  • Patent number: 11989618
    Abstract: A two-dimensional code processing method and a device. The method includes: obtaining, by a first electronic device, two-dimensional code information displayed by a second electronic device; obtaining first scenario information, where the first scenario information is scenario information related to the first electronic device; determining two-dimensional code data and second scenario information based on the two-dimensional code information, where the second scenario information is scenario information related to the second electronic device; and when determining that the first scenario information and the second scenario information meet a preset condition, performing, by the first electronic device, preset processing on the two-dimensional code data. The scenario information of the two electronic devices that need to perform two-dimensional code interaction is compared, and further, two-dimensional code verification is completed.

  • Publication number: 20230281135
    Abstract: A method for configuring an address translation relationship is disclosed. The method is applied to a computer system. A rich execution environment REE and a trusted execution environment TEE are deployed in the computer system, a virtual machine VM and a virtual machine manager VMM are deployed in the REE, and a secure partition SP and a secure partition manager SPM are deployed in the TEE. The method includes: The VMM transfers a first address translation relationship to the SPM. The first address translation relationship includes an address translation relationship from an intermediate physical address IPA allocated to the VM to a physical address PA, so that the SPM performs IPA-to-PA address translation based on the first address translation relationship when transmitting data from the SP to the VM. The PA is a memory address. The method simplifies a process in which the SPM establishes an IPA-to-VA address mapping relationship.
