[isabelle] New AFP Entry: Hotel Key Card System



It is my pleasure to announce a new AFP entry:

Verifying a Hotel Key Card System
Tobias Nipkow

Two models of an electronic hotel key card system are contrasted: a
state based and a trace based one. Both are defined, verified, and
proved equivalent in the theorem prover Isabelle/HOL. It is shown that
if a guest follows a certain safety policy regarding her key cards,
she can be sure that nobody but her can enter her room.

This theory comes with a paper that will appear in the proceedings of ICTAC 2006 http://www.iist.unu.edu/ICTAC2006/

Note:
This article is only available in the development version of the AFP.

Enjoy!
Tobias Nipkow
