METHOD AND APPARATUS FOR AUTHENTICATING DATA

摘要

A method for authenticating a string of data stored remotely from the processor. A bifurcated hash routine can be utilized to provide a check root (116) along with a putative new root (112) for a revised string of data (108). The check root can be compared (120) with the previously determined initial root (104). If the check root matches the initial root, the new root is accepted in view of the fact that it was computed concurrently with the check root (124).
