Abstract
In a data packet communications network capable of transmitting a digitally coded data packet message including an error-check code from a source node to a destination node over a selected transmission link which includes at least one intermediate node operative to intentionally alter a portion of a message to form an altered message which is ultimately routed to the destination node, a method of recomputing at the intermediate node a new error-check code for the altered message with a predetermined number of computational operations, i.e. computational time, independent of the length of the message, while preserving the integrity of the initially computed error-check code of the message.
