Abstract:
1. A receiver-initiated method for secure transmission of information over a network from a sender to a receiver, said network having a nonce server, said method comprising the steps of: A1) receiving a request for said information from said receiver; A2) generating a nonce at said nonce server in response to the request for said information; B) transmitting said nonce from said nonce server to said receiver; C) encrypting said nonce at said nonce server, using a key from a key server that is physically separate from said nonce server and that is not accessible by said sender or said receiver; D) receiving said information from said sender at said nonce server; E) decrypting said nonce at said nonce server, using a key from a key server that is physically separate from said nonce server and that is not accessible by said sender or said receiver; F) encoding said information with said nonce at said nonce server using the results of said step E); F1) transmitting the results of said step F) to said receiver; G) decoding said information using the results of said step B); H) Deleting said nonce from said nonce server, said step H) being immediately accomplished after completion of said step F) and before accomplishment of said step G); I) deleting said nonce from said nonce server, said step I) being accomplished if said step D) is not initiated within a predetermined amount time after the accomplishment of said step C); and, said step C) through said step F) being accomplished while said receiver is disconnected from said network, said step A1) through said step C) being accomplished before said sender logs on to said network.
