Abstract
A method, node and identifier authorizing entity for generating a unique identifier at a node in a hierarchal tree having a plurality of nodes, the hierarchical tree arranged in a plurality of levels. The method includes obtaining a first limit condition from a higher level node of the plurality of nodes in the hierarchal tree, generating the identifier, applying a function to the generated identifier, verifying that an output of the function satisfies the limit condition, determining a second limit condition for at least one lower level node of the plurality of nodes in the hierarchal tree, and sending the second limit condition to the at least one lower level node of the plurality of nodes in the hierarchal tree.
