ABSTRACT:
A device for generating an authenticator code by encrypting the contents of a plain text message in accordance with a unique user supplied authenticator key variable. The device operates in two phases, the first of which processes every character in the plain text message and produces a first sequence of 16 check bits. The second phase processes this first 16 check bit sequence and transforms it into a second sequence of 16 check bits which may be utilized as an authenticator code.
