Abstract
Communication over data links using binary synchronous protocol that is to be made secure according to the Federal data encryption standard (DES) is enhanced by utilizing an encrypted message format wherein the initialization vector for the DES algorithm is at the trailing end of the message. Additional information or control words may also be strung at the trailing end of the encrypted message format without causing throughput loss while enhancing the security and flexibility of the encrypted message in both point-to-point and multipoint systems.
