Context-Driven Assessment of Provider Reputation in Composite Provision Scenarios [chapter]

Lina Barakat, Phillip Taylor, Nathan Griffiths, Simon Miles
2015 Lecture Notes in Computer Science  
Such information is particularly important in composite service provision scenarios, where providers may delegate sub-tasks to others, and thus their success or failure needs to be interpreted in this  ...  assessment process, adjusting the contributions of past interactions with the composite service provider according to delegation context relevance.  ...  This work was part funded by the UK Engineering and Physical Sciences Research Council as part of the Justified Assessments of Service Provider Reputation project, ref. EP/M012654/1 and EP/M012662/1.  ...

Dependability-driven runtime management of service oriented architectures

Hanen Haouas, Johann Bourcier

Security and Trustworthiness Threats to Composite Services: Taxonomy, Countermeasures, and Research Directions [chapter]

Per Håkon Meland, Muhammad Asim, Dhouha Ayed, Fabiano Dalpiaz, Edith Félix, Paolo Giorgini, Susana Gonzáles, Brett Lempereur, John Ronan
2014 Lecture Notes in Computer Science  
Our main contributions are a taxonomy of threats for composite services in the Future Internet, which organises thirty-two threats within seven categories, and a corresponding taxonomy of thirty-three  ...  For instance, while atomic services may, in isolation, comply with privacy requirements, a composition of the same services could lead to violations due to the combined information they manipulate.  ...  Research method In order to study the threats related to composite services, we have employed a scenario-driven method to identify the most relevant types of threats based on both the knowledge of the  ...
