We investigate the framework for long-term validation of
timestamps based on the framework for long-term validation
of electronic signature. We evaluate several schemes from
the view point of the user convenience, especially
investigating whether long-term validation can be achieved
solely by a TSA service and whether a wide range of risks are
covered, in a scheme. We show that the two requirements
cannot be fulfilled under a scheme based on the conventional
electronic signatures, and they can be fulfilled under
our proposed DS-IMT scheme. |
