- Title:
- NONREPUDIATION PROTOCOLS
For electronic business to mature, electronic transactions have to be
made binding for sender and receiver. Digital signatures meet the
original goals of non-repudiation quite adequately, but often further
requirements are added, which demand the involvement of some trusted
third party.
This talk will give an outline of current suggestions for
non-repudiation protocols, discuss in more detail one particular
protocol which tries to reduce the involvement of the trusted third
party, and raise some points regarding the design and verification of
such protocols.
