Rethinking Digital Signatures

Ueli Maurer

Proc. of SECRYPT 2008, INSTICC, pp. IS-31–IS-33, Jul 2008.

Digital signatures are a core enabling technology for evidence management in the context of the automation and digitization of business and government processes. The main advantages over conventional signatures are that they are easy to transmit, archive, search, and verify, and, moreover, promise to achieve a high level of security. Nevertheless the initial expectations for the usefulness of digital signatures were too optimistic. This calls for a systematic treatment of digital signatures and more generally digital evidence. The goal of this talk is to provide a foundation for reasoning about digital evidence systems and legislation, thereby identifying the roles and limitations of digital evidence.
