ABSTRACT:
In one exemplary embodiment, a method includes: providing an abstract tree structure having a root node, tree nodes, and leaf nodes, each leaf node corresponds to a 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 to the root node, tree nodes, and leaf nodes; storing, at each first network node, the unique identifier of the corresponding tree node, the unique identifier of a parent, and the unique identifiers of children; storing, at each second network node, the portion of data and path information; providing a distributed hash tree wherein the DHT includes a hash value 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 the hash values of children.
