Objectives

(1)    Map the QSC transition in online communication, specifically end-to-end encrypted messaging services like WhatsApp.

(2)    Analyse the impact of EU digital regulation on the tension between interoperability and (post-quantum) security of messaging services.

(3)    Evaluate stakeholders’ perception of the implications of the use of QSC protocols for interoperable messaging services.

Contribution to project

This WP focuses on how the quantum-safe transition in the context of interpersonal communications services (messaging apps) interacts with EU digital regulations that aim to empower users and guarantee competition through interoperability. Contributions include: organizing workshops with regulators and technical experts; surveying / interviewing users about how they engage with interoperability settings in messaging apps; co-design exercises about future customizable interfaces for choosing the type of interoperability across services a user may opt for.
