Abstract
A method for processing and verifying remote dynamic data is provided. The method includes providing a radix tree structure having N levels, obtaining and recording N initial values for representing the empty radix tree structure, wherein all nodes at the same level are assigned an identical initial value. When performing a data processing operation to the radix tree structure, determining a first leaf node and calculating and recording the value of each node in a shortest path from the first leaf node to the root node. When performing a verification of a specific data, obtaining a second leaf node corresponding to the specific data, a sibling node of each node in a shortest path from the second leaf node to the root node, and generating a verification result according to a digital signature for verifying the root node, the value of each obtained sibling node, and the specific data.
