CRYPTOPOST A cryptographic application to mail processing

A public key cryptography protocol is designed for the authentication of documents. When applied to the authentication of postage on mail envelopes it permits the development of a universal automated and standardized mail processing and postage verification system. The mail processing automation problem is present, and the protocol solution and characteristics of the proposed cryptographic CRYPTOPOST™ system are described. Partial details of one implementation are disclosed.
