| Abstract(in English) | Time-stamping digital documents is now becoming increasingly important. Several time-stamping schemes have been proposed and some of them have been put into service. There are, however, several problems with existing time-stamping systems, such as expiration of public-key certificates, key compromise and existence of single point of attack. In this paper, we propose a new time-stamping scheme that is intended to solve these problems by using an event-ordering system, and present a threat analysis of the scheme. |
