ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to encryption and, more particularly, to digital signatures.
2. Background Information
Encryption, digital signatures, and digital certificates are well-known. See, for example, APPLIED CRYPTOGRAPHY, written by Bruce Schneier, available from John Wiley and Sons, Inc. (1994), herein incorporated by reference. The state of the art notion of a digital signature is as encrypted, electronic signals, physically stored with a collection of electronic signals in an electronic file. The digital signature provides verification or validation with respect to the collection. A need, however, exists for a method of using a digital signature that provides greater flexibility than current approaches.
SUMMARY OF THE INVENTION
Briefly, in accordance with one embodiment of the invention, a method of using a digital signature includes: electronically referencing at least one plurality of electronic signals with a digital signature remotely stored from the plurality.
