Abstract. Much research on Internet security has concentrated so far
on generic mechanisms such as firewalls, IP authentication and protocols
for large scale key distribution. However, once we start to look at
specic applications, some quite dierent requirements appear. We set
out to build an infrastructure that would support the reliable electronic
distribution of books on which doctors depend when making diagnostic
and treatment decisions, such as care protocols, drug formularies and
government notices. Similar requirements will be essential for other areas
of human activities such as electronic commerce.
We initially tried to implement a signature hierarchy based on X.509 but
found that this had a number of shortcomings. We therefore developed
an alternative way to manage trust in electronic publishing, that has a
number of advantages which may commend it in other applications. It
does not involve the use of export-controlled cryptography; it uses much
less computational resources than digital signature mechanisms; and it
provides a number of features that may be useful in environments where
we are worried about liability.
Yet another alternative involves use of one-time signatures. We have
actually implemented one-time signatures for one version of the medical
publishing system. This system initially used the familiar X.509 and
RSA based signature mechanisms; the move to one-time signatures enabled
considerable simplication, cost reduction and performance improvement.
We believe that similar mechanisms may be appropriate for
protecting other information that changes slowly and remains available
over long time periods. Book and journal publishing or legal announcements
in general appear to be strong candidates.
