摘要：In one exemplary embodiment, a method includes: providing an abstract treestructure having a root node, tree nodes, and leaf nodes, each leaf node corresponds toa portion of data; mapping first network nodes of a distributed network to the tree
nodes; mapping second network nodes to the leaf nodes; assigning unique identifiers tothe root node, tree nodes, and leaf nodes; storing, at each first network node, the uniqueidentifier of the corresponding tree node, the unique identifier of a parent, and theunique identifiers of children; storing, at each second network node, the portion of dataand path information; providing a distributed hash tree wherein the DHT includes a hashvalue for each node of the ATS signing the top hash value for the root node; and storing,at each second network node, the corresponding hash value of the tree node and thehash values of children.
