| Abstract | In this thesis, we examine the current state of the most widely used public key infrastructure model and secure time-stamping systems. We begin by giving an overview of the evolution of the time-stamping techniques to show the direction of research. We identify some problems in PKI and time-stamping that need solutions in practice. The problems are not very bad today but are becoming worse as time goes on and people start using these services more and more. Both problems are essentially scalability problems. We show a simple and known solution attempt to the problem with PKI. The solution doesn't work either but gives a hint for building a working solution. Using the hints we present a working solution for the PKI problem. The new protocol eliminates certi cate revocation lists and reduces the number of time stamps required since no time stamps are needed any more for the PKI itself. We also point the similarities between the new system and some existing time-stamping systems. We analyze the similarities and develop another new protocol that integrates the rst new protocol with time-stamping and solves the scalability problem for time-stamping. The integration allows to build the temporal authentication of signed data tightly into the PKI. |
