key notarization
Definition: a method for encrypting information at a terminal site before transmission to a host computer, over communications media that might not be secure. It is necessary for the host and the terminal to maintain the same encryption key and algorithm. This is frequently accomplished by downloading (sending information) from the host to the terminal on key changes. The downloaded information must also be encrypted. |
