About Viber Messenger: The Importance of Authentication Ceremony in Secure Messaging Apps

The advent of secure messaging applications has revolutionized the way we communicate, providing an added layer of protection for our conversations. However, researchers have highlighted that the effectiveness of these apps' security measures heavily relies on users completing an authentication ceremony - a sequence of manual operations designed to verify that users are indeed communicating with one another.

A recent study presented at the Thirteenth Symposium on Usable Privacy and Security found that explicit instructions regarding the authentication ceremony led to a significant increase in users completing it. However, the participants took an average of 11 minutes to do so, revealing the complexity and confusion surrounding this process.

In essence, the authentication ceremony allows users to confirm the identity of their intended conversation partner and ensures that no third party can trick them into revealing the contents of their messages. Unfortunately, many popular messaging apps, including WhatsApp and Viber, tout their end-to-end encryption as automatic, leading users to believe that their conversations are secure without realizing that true encryption requires an authentication ceremony.

For instance, even though Viber claims its encryption is automatic, it actually relies on this ceremony to ensure the security of messages. Similarly, Facebook Messenger doesn't offer automatic encryption but allows users to set it up themselves.

The findings of this study emphasize the importance of understanding the authentication ceremony and how it contributes to the overall security of secure messaging applications. According to Daniel Zappala, a computer science professor who worked on the study, 'a clever hacker could make you think that you are encrypting your messages to your partner (let's call her Alice), when in reality, you are encrypting your messages for an intruder (let's call her Trudy).'

In conclusion, while secure messaging apps have made significant strides in protecting our conversations, it is crucial to comprehend the authentication ceremony and its role in ensuring the integrity of our online communications. By doing so, we can better understand the importance of manual verification and take steps to safeguard our digital interactions.
