Abstract
A processor obtains a first child node in response to a read request for target data when the first child node is not verified in the processor. The first child node is a child node that is in an integrity tree and that is related to the target data. The integrity tree includes a plurality of root nodes and a plurality of child nodes. The plurality of root nodes are in a decompressed state and the plurality of child nodes are in a compressed state. The processor decompresses the first child node in the compressed state, and caches the decompressed first child node into the processor for integrity verification on the target data. The plurality of child nodes of the integrity tree are stored in a form of the compressed state in the memory, so that storage space of the memory can be saved, and the sizes of the child nodes can be reduced.
