Security Group Seminar, 10th May 1994
The purpose of any security service is either to ensure that an event
happens or to prevent an event happening (liveness or safety). Software
reliablity is typically concerned with events that are universally
agreed to be beneficial or harmful. On the other hand, computer
security is typically concerned with events that are beneficial to some
persons while harming others.

- WIRETAPPING, FORGERY AND PLAUSIBLE DENIABILITY:
- THE NEW SECURITY SERVICES
It follows that whether a computer security service is desirable or not
depends upon who you are, and how you are effected by the events that
it causes or prevents.
Traditionally, research interest has been focused on the services known
as confidentiality, integrity and non-repudiation, and has neglected
the converse services of wiretapping, forgery and plausible
Recent proposals for national cryptographic infrastructures are
attempting to redress this historical imbalance. We will describe some
possible protocols for achieving these new services, both with and
without the use of trusted third parties.
