Abstract: An access object authentication technology is provided. A trusted component in a computing device completes an access object authentication process. When a client requests to access a target object, the trusted component receives an object 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: A data processing method for a network adapter includes the network adapter that obtains a first input/output (I/O) command. The first I/O command instructs to store first data in at least one remote server to a local server, and the first I/O command includes address information and length information that are of the data and that are stored in the local server. The network adapter splits the first I/O command based on the address information and the length information to obtain a plurality of I/O read messages. The network adapter sends the I/O read messages to the at least one remote server.

Abstract: A non-volatile memory express (NVMe)-based data read method, apparatus, and system are provided. In various embodiments, a read instruction can be triggered by a host. The read instruction carries indication information of a first address opened by the host to an NVMe controller for addressing and accessing. In those embodiments, the host after obtaining the read instruction can send a data packet to the host. The data packet carries the first address and payload data. Still in those embodiments, the host can, after receiving the data packet, determine a second address based on the first address, and store the payload data into storage space indicated by the second address. The second address may be a private memory address of the host. Because a relationship between the second address and a communication protocol is broken, and the host may access the second address without being restricted by the communication protocol.
