Abstract

A 'pragmatic' alternative to undetachable signatures is proposed. Undetachable signatures were introduced by Sander and Tschudin, [4], as a means of giving a mobile agent the means to sign a message on behalf of a user, without endangering the user's private key. The alternative discussed in this paper involves the use of conventional signatures and public key certificates.
