Claim 9:
10. The system of claim 7,
wherein the oriented tree is a two-dimensional matrix graph,
wherein a first node in each row in the two-dimensional matrix graph comprises a longitudinal sub-node and a transverse sub-node, a last node in each row does not comprise any sub-node, and remaining nodes of the oriented tree each only comprises a transverse sub-node,
wherein nodes in a first column in the two-dimensional matrix graph perform iterations via a first one-way function, and nodes in each row in the two-dimensional matrix graph perform iterations via a second one-way function, and
wherein the topological order number of each node in each row decreases one by one, and the topological order number of the last node in each row is greater than that of all nodes on its next row.
