Method and apparatus for generating digital checksum signatures for alteration detection and version confirmation

摘要

A method is described for generating a digital checksum signature for a collection of data. According to the method, a first operation is performed on the collection of data to generate a first encoded result. The first encoded result is used to define a first portion of the digital checksum signature. A second operation is performed on the collection of data to generate a second encoded result. The second encoded result is used to define a second portion of the digital checksum signature.
