Abstract:
This paper extends Shanon's concept of a 'work factor' to provide an
objective measure of the practical security offered by a protocol or
infrastructure design. Considering the hypothetical work factor based
on an informed estimate of the probable capabilities of an attacker
with unknown resources provides a better indication of the relative
strength of protocol designs than the computational work factor of
the best known attack.
The social work factor is a measure of the trustworthiness of a
credential issued in a PKI based on the cost of having obtained the
credential through fraud at a certain point in time. Use of the
social work factor allows evaluation of Certificate Authority based
trust models, peer to peer (Web of Trust) models to be evaluated in
the same framework. The analysis shows that each model has clear
benefits over the other for some classes of user but most classes of
user are served better by a combination of both.
