Abstract: In this plenary talk, we discuss the role of Petri Nets and Object-Centric Processes in recent development of Software Engineering. Namely, we illustrate how extended Petri nets can be used to define a low-code language for modelling and development of software systems and web applications based on object-centric processes. Among others, we define key requirements for a low-code language for object-centric processes with forms. Such a language should enable to model object-centric processes consiting of data attributes, the life cycle of data attributes given by a workflow of tasks, and forms linked to these tasks consisting of subsets of data attributes. In addition, we specify requirements for handling events related to artifacts of object-centric processes, namely process instances, data fields, and tasks, resulting in a class of discrete event systems. We also discuss how roles specifying which users can trigger events should be represented within such a language. Finally, we outline requirements for a query language capable of searching on object-centric processes and their tasks. We also provide a prototype of such a language based on Petri nets enriched by data attributes, called Petriflow. Finally, we give an illustrative example of an application implemented using presented low-code language Petriflow.

Abstract: This plenary talk addresses the primary challenges of adapting digital technologies to the post-quantum era in connection with development of 6G infrastructures. Particularly it highlights the research problems in the area of 6G massive machine-type communication security, as well as the protection of information in cloud environments.The talk outlines current research trends that aim to mitigate these challenges and pave the way for the successful implementation of 6G technologies. These include:

  • Regeneration coding for cloud systems.
  • Physical layer security.
  • Integrated sensing and communication.
  • Quantum key distribution.
  • Quantum communication.

Finally, the objectives of the COST Action CA22138 project, titled Physical Layer Security for Trustworthy and Resilient 6G Systems (6G PHYSEC), will be presented. The project aims to address several of the aforementioned challenges and contribute to the development of secure and resilient 6G systems.
