We’re excited to announce that starting Oct 19, Zoom’s end-to-end encryption (E2EE) offering will be available as a technical preview, which means we’re proactively soliciting feedback from users for the first 30 days. Zoom users – free and paid – around the world can host up to 200 participants in an E2EE meeting on Zoom, providing increased privacy and security for your Zoom sessions.
We announced in May our plans to build an end-to-end-encrypted meeting option into our platform, on top of Zoom’s already strong encryption and advanced security features. We’re pleased to roll out Phase 1 of 4 of our E2EE offering, which provides robust protections to help prevent the interception of decryption keys that could be used to monitor meeting content.
•How does Zoom provide end-to-end encryption? Zoom’s E2EE offering uses public key cryptography. In short, the keys for each Zoom meeting are generated by participants’ machines, not by Zoom’s servers. Encrypted data relayed through Zoom’s servers is indecipherable by Zoom, since Zoom’s servers do not have the necessary decryption key. This key management strategy is similar to that used by most end-to-end encrypted messaging platforms today.
•How do I turn on E2EE? Hosts can enable the setting for E2EE at the account, group, and user level and can be locked at the account or group level. All participants must have the setting enabled to join an E2EE meeting. In Phase 1, all meeting participants must join from the Zoom desktop client, mobile app, or Zoom Rooms.
•When would I use E2EE? E2EE is best for when you want enhanced privacy and data protection for your meetings, and is an extra layer to mitigate risk and protect sensitive meeting content. While E2EE provides added security, some Zoom functionality is limited in this first E2EE version (more on that below). Individual Zoom users should determine whether they need these features before enabling this version of E2EE in their meetings.
