Abstract

This paper presents the Secure Blackboard pattern as a secure version of the original Blackboard pattern and Shared Resource pattern. The Blackboard pattern is an architectural pattern useful for problems for which no deterministic solution strategies are known. Several specialized subsystems or components "assemble" their knowledge to build a possibly partial or approximate solution, coordinated by a central controller. On the other hand, the Shared Resource pattern is a specialization of the Blackboard pattern, in which subsystems or components are allowed to perform simultaneous computations without a prescribed order on different, ordered data. The Secure Blackboard pattern includes ways to add security at the control component, providing secure handling of data, as well as controlling data transformation and movement.
