Digital Samba Introduces End-to-End Encryption (E2EE) for Private and Group Video Calls

Written by Digital Samba | August 23, 2023

Security and privacy are the number one priority at Digital Samba. We're thrilled to announce the release of our 'End-to-End Encryption' (E2EE) feature.

With this update, we make end-to-end encryption for group calls available to our customers. Traditional methods require decryption of streams on the provider’s server before relaying them to other participants.
E2EE eliminates this potential weak point by ensuring the data is only decrypted by the intended recipient, providing a more secure path for all your embedded audio, video, screen sharing, and messaging data.
This means that the data is only accessible to the intended recipients and cannot be read or modified by unauthorised users.
 

E2EE for Large Group Calls

Unlike many providers who limit end-to-end encryption (E2EE) to 1-1 sessions, Digital Samba stands out by offering E2EE for group calls, currently supporting up to 100 participants. We're not stopping there; plans are underway to extend E2EE to even larger calls in the near future. Whether you're hosting a private one-on-one discussion or a sizeable team meeting, with Digital Samba, you can be assured that your communications are encrypted and protected at all times.

DTLS and E2EE

In the realm of real-time communication, WebRTC employs DTLS-RTP as its foundational transport encryption mechanism, serving as a robust protective layer for transmitted data. In straightforward peer-to-peer configurations, this encryption inherently safeguards data between participants. However, when scaling to accommodate larger conferences, the architecture transitions to the Selective Forwarding Unit (SFU), where data traverses a central server prior to distribution to attendees. To counteract this vulnerability, Digital Samba integrates E2EE, introducing an advanced encryption layer. E2EE ensures impenetrable confidentiality, rendering the data inaccessible, even to intermediary servers. It guarantees that streams are encrypted to the extent that even we, as the service provider, cannot access the raw data.
 

Key Features of End-to-End Encryption in Digital Samba

By offering E2EE with a developer-first approach, Digital Samba ensures that both the user experience and backend processes are secure, making it a top choice for developers who prioritise security in video conferencing tools.

Enhanced Security with an Additional Layer of Protection

To enhance your security measures, we have implemented an additional security code feature. When users click on the E2EE green badge icon inside the room, they will be presented with an 80-digit security code. This code is a cryptographic SHA-256 hash of the public keys of all users within the room. Users can compare each other's security code values to ensure there are no eavesdroppers or malicious man-in-the-middle attackers.

How to Enable E2EE in Digital Samba

With E2EE, you can have peace of mind knowing that your communications are protected from potential eavesdroppers. To enable E2EE in the Digital Samba dashboard or via API, follow the steps outlined in the official documentation.

Digital Samba's Commitment to Privacy

Digital Samba stands firm in its commitment to user privacy. We don't gather or share customers’ or users’ data. Proudly European, Digital Samba is fully aligned with GDPR standards, prioritising privacy by structuring its platform to be data-agnostic.

In Conclusion

Digital Samba, a pioneer in the video conferencing API industry, remains dedicated to ensuring the safety and security of its users. With the introduction of End-to-End Encryption, we're taking a significant step forward in ensuring that your video conferencing experience is not only seamless but also secure.
