How to Make a Digital Whiteboard Secure -
Using JAVA-Cards for Multimedia Application
Abstract
In this paper
we propose a light-weight, provable secure smart
card integration for the
OpenPGP secure message format. The basic idea is
that the secret
keys are stored on
a smart card and never leave it.
We have integrated this new security approach
into an enhanced
whiteboard, the digital lecture board (dlb).
Existing whiteboards neglect
security mechanisms
almost
completely,
even though these mechanisms are extremely important to allow
confidential private sessions and billing. The primary
application field of our concept are small and closed groups,
whereas the smart card serves to testify group membership.
Our first implementation supports
the JAVA i-Button which provides an additional
hardware security.
