摘要: A signature system with a mechanism to identify element(s) of a signed document includes a sender having a signature module with a digest generator. The digest generator generates digests for identifying selected elements of the document. The resulting “identifying” digests are then used in generating a signature in which the sender signs the digests rather than the original elements. The receiver can then process the signature and use these digests to distinguish between elements, as needed.
