abstract

  • © IFCA/Springer-Verlag Berlin Heidelberg 2003. In this paper we investigate the timed release of standard digital signatures, and demonstrate how to do it for RSA, Schnorr and DSA signatures. Such signatures, once released, cannot be distinguished from signatures of the same type obtained without a timed releajse, makingit transparent to an observer of the end result. While previous work has allowed timed release of signatures, these have not been standard, but special-purpose signatures. Building on the recent work by Boneh and Naor on timed commitments, we introduce the notion of a reusable time-line, which, besides allowing the release of staindard signatures, lowers the session costs of existing timed applications.
