摘要

A system for conveying information for the reliable authentication of a plurality of documents includes a device for solving a set of polynomial equations to develop a string of characters and having a decryption key therein that, upon application to the string of characters provided, reveals not only a plain text message indicating the source of the authentication but, in addition, provides the decryption key for use with the information provided by the mailer. The solution of the set of polynomial equations requires the accumulation of individual documents, each having a random xi and a solution f(xi) associated therewith.
