Abstract
One embodiment provides a method for enabling computation of a signature of an information set given change information by storing information in a hierarchical data structure, the method including: utilizing at least one processor to execute computer code that performs the steps of: receiving change information relating to a first node within the hierarchical data structure; accessing a database comprising at least one key, wherein the at least one key comprises a crypto-hash and is assigned to a node within the hierarchical data structure; identifying a node key within the database that is assigned to the first node; computing a node crypto-hash for the first node after modifying the first node using the received change information; modifying the node key based upon the computed node crypto-hash; and updating the database with the modified node key. Other aspects are described and claimed.
