Abstract:
We state the basic requirements for time-stamping systems applicable as the necessary support to the legal use of electronic documents. We analyze the main drawbacks of the time-stamping systems proposed to date and present a new system that meets all the stated requirements. We prove that these requirements cannot be significantly tightened..
