Instant messaging (IM) protocols like WhatsApp have become an integral part of everyday life for many people. Private or professionally sensitive data is often exchanged in this way. In contrast to classic electronic communication media such as e-mail or SMS, all communication runs through just one organization. Many IM systems have been provided with far-reaching security guarantees, including new security goals such as “Future Secrecy”. The aim of the research tandem is to investigate the accessibility and compliance with these security goals and to focus on people as direct users of IM protocols.
