“…We take advantage of the automata expressiveness to implement complex security NFRs into the desired service composition. An example of implementing complex security attributes into automata modeling is the integration of the Shamir multi-cloud sharing algorithm in a previous study [47]. In our current approach, we adopt this modeling method to address the challenges of designing blockchain interactions.…”

Collaborative business activities have aroused great interest from organizations because of the benefits they offer. However, sharing data, services, and resources and exposing them to external use can prevent organizations involved in collaboration from being engaged. Therefore, the need for advanced mechanisms to ensure trust between the different parties involved is paramount. In this context, blockchain and smart contracts are promising solutions for performing choreography processes. However, the seamless integration of these technologies as non-functional requirements in the design and implementation phases of inter-organizational collaborative activities is a challenging task, as reported in the literature. Consequently, we aim in the proposed approach to extend the modeling and implementation of the choreography lifecycle based on service-oriented processes. This is fulfilled by integrating blockchain transactions and smart contract calls, to allow collaboration and interoperability between different entities while guaranteeing trust and auditability. Moreover, to conduct this extension efficiently we use a BPMN choreography diagram combined with Finite State Automata to ensure a meticulous modeling which targets the processes' internal interactions. Hyperledger Fabric is used as a permissioned blockchain for proof-of-concept implementation. A use case of COVID-19 collaborative processes is used to experiment our approach, which aims to guarantee a fluid collaboration between healthcare providers and epidemiological entities at a national scale in Morocco.

“…An information system is considered to be secure if it has well-defined security measures and characteristics such as authenticity, confidentiality and integrity [11]. Security in service composition has been considered in the literature [12,13], but has been overlooked when Workflownets are used to compose services. In this paper, a closed form Workflow-net based mathematical model is proposed that ensures such security characteristics are satisfied both structurally and behaviorally.…”

Mobile cloud service subscribers acquire and produce both simple and complex services resulting in tremendous amounts of stored data. Increasing demand for complex services coupled with limitations in current mobile networks has led to the generation of cloud service composition solutions. In this paper, we introduce a cloud mobile subscriber data caching method that allows cloud subscribers to retrieve data in a faster and more efficient way. The solution also allows the retrieval of user-specific composed data through a service-specific overlay (SSO) composition technique. Additionally, a Workflow-net based mathematical framework called Secure Workflownet is proposed to enhance security attributes of SSOs. Simulation results show increased successful file hit ratio and demonstrate how task coverage is achieved in an adequate timely manner when constructing service composition workflows.
