Abstract
NTSC and Uni-trust are constructing the public time-stamping service platform of China. In this paper, we present the architecture of Time-Stamping service and analyze the threats are encountered in each time-stamping system. Then we propose a modified architecture for overcoming these threats. This architecture is relies on a secure time service to obtain a authentic time stamp from the Time Authority, and makes the client obtain a trusted time from the TSA during the time-stamping service. This method improves the security of time service in time-stamping service.
