Enforcing Integrity of Execution in Distributed Workflow Management Systems

Frederic Montagut, Refik Molva
2007 IEEE International Conference on Services Computing (SCC 2007)  
These mechanisms can easily be integrated into distributed workflow management systems as our design is strongly coupled with the runtime specification of decentralized workflows.  ...  As a result, this flexible decentralized setting raises specific security requirements, such as the compliance of the overall sequence of operations with the pre-defined workflow execution plan, that are  ...  These approaches do not address the issue of policy enforcement with respect to integrity of execution in fully decentralized workflow management systems.  ...

Florian Gallay, Yliès Falcone
2021 Electronic Proceedings in Theoretical Computer Science  
We consider the runtime enforcement of Linear-time Temporal Logic formulas on decentralized systems with no central observation point nor authority.  ...  We formalize the decentralized runtime enforcement problem and define the expected properties of enforcers, namely soundness, transparency and optimality. We present two enforcement algorithms.  ...  We address the problem of enforcing LTL formulas on decentralized systems. We start by defining the runtime enforcement problem in the decentralized setting.  ...
