Sensoria Bibliography Site Synthesis of Local Controller Programs for Enforcing Global Security Properties
Fabio Martinelli, Ilaria Matteucci
abstract:
In this paper we present a framework based on contexts
theory and logic to study how, given a partially specified
system, i.e., a system in which there are some unspecified/
unknown components, i.e., potential attackers, it is possible
to enforce a global security property by controlling all the
unspecified parts of the given system. We propose two meth-
ods to control them: A centralized method, in which there is
a unique controller program that controls all the unspeci-
fied components, and a decentralized one in which each un-
specified component is monitored by a controller program
that forces it to behave correctly, i.e., according to a local
requirement found by a reduction of the global one. In both
cases we show how to synthesize controller programs that
solve the problem.
