Abstract: An access object authentication method includes a trusted component that is in a computing device and that completes an access object authentication process. When a client requests to access a target object, the trusted component receives an object identifier (ID) and an authentication ID of the target object from the client to perform, based on the authentication ID, tenant authentication on a tenant to which the client belongs. When the authentication on the tenant to which the client belongs succeeds, the trusted component accesses a storage device based on the object ID of the target object.

Abstract: This application relates to a bus monitoring and controlling method, an electronic device, a chip, and a storage medium. The method is applied to an integrated circuit device. The integrated circuit device monitors communication data between a master and a slave on an SPMI bus. If it is determined based on the communication data that a working state of the integrated circuit device is a first working state, and the SPMI bus is in an idle state, the integrated circuit device performs bus arbitration on the master by simulating the slave, performs bus arbitration on the slave by simulating the master, and controls switching of a switch module, so that the integrated circuit device is separately connected to the master and the slave. When it is determined that the master with the highest priority preempts the SPMI bus, the integrated circuit device sends supplementary data to the slave.
