4.  Security Considerations

   This document specifies a data integrity service that protects data
   from accidental modification while in transit from the sender to the
   recipient.  A secure data integrity service, such as that provided by
   Privacy Enhanced Mail [3], is conjectured to protect data from all
   modifications.

5.  Acknowledgements

   This memo is based almost entirely on text originally written by
   Nathaniel Borenstein of Bellcore.  In addition, several improvements
   were suggested by Keith Moore of the University of Tennessee,
   Knoxville.
