Exhibit 31

                                       CERTIFICATION

      I, Margaret E. Grayson, certify that:

1.    I have reviewed this annual report on Form 10-K/A of V-ONE Corporation;

2.    Based on my knowledge,  this report does not contain any untrue  statement
of a  material  fact or omit to  state a  material  fact  necessary  to make the
statements made, in light of the circumstances  under which such statements were
made, not misleading with respect to the period covered by this report;

3.    Based on my  knowledge,  the  financial  statements,  and other  financial
information included in this report, fairly present in all material respects the
financial  condition,  results of operations and cash flows of the registrant as
of, and for, the periods presented in this report;

4.    The  registrant's  other  certifying  officer(s) and I are responsible for
establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and we have:

       a) designed  such  disclosure  controls  and  procedures,  or caused such
       disclosure  controls and procedures to be designed under our supervision,
       to ensure that material information relating to the registrant, including
       its consolidated subsidiaries, is made known to us by others within those
       entities,  particularly  during the period in which this  report is being
       prepared;

       b) evaluated the  effectiveness of the registrant's  disclosure  controls
       and  procedures  and presented in this report our  conclusions  about the
       effectiveness of the disclosure controls and procedures, as of the end of
       the period covered by this report based on such evaluation; and

       c) disclosed  in this  report  any  change in the  registrant's  internal
       control over financial  reporting that occurred  during the  registrant's
       most recent fiscal quarter (the registrant's fourth fiscal quarter in the
       case of an annual report) that has materially affected,  or is reasonably
       likely to  materially  affect,  the  registrant's  internal  control over
       financial reporting; and

5.    The registrant's other certifying  officer(s) and I have disclosed,  based
on our most recent evaluation of internal control over financial  reporting,  to
the registrant's  auditors and the audit committee of the registrant's  board of
directors (or persons performing the equivalent function):

       a) all significant  deficiencies and material weaknesses in the design or
       operation  of  internal  control  over  financial   reporting  which  are
       reasonably likely to adversely affect the registrant's ability to record,
       process, summarize and report financial information; and

       b) any fraud, whether or not material,  that involves management or other
       employees  who  have a  significant  role  in the  registrant's  internal
       control over financial reporting.
