Abstract
Authentication by an intermediary F (e.g. a bank) of an originator C of a message (e.g. a client sending an instruction to pay a merchant M) is accomplished using a protocol which does not require the intermediary to possess passwords used by the originator C and the merchant M to protect the contents of the message. Furthermore, the protocol does not require any party to the transaction to decrypt any value previously encrypted by any other party, so a reversible encryption algorithm is not required.
