Learn about Meet Client-side Encryption (CSE)

Important:

  • CSE meetings must be created by  a user with one of these Workspace editions:
    • Education Standard
    • Education Plus
    • Enterprise Plus
  • CSE meetings can’t be created in the Google Meet app .
    • CSE meetings can only be created on mobile in the Google Calendar app Calendar.
  • You can join a CSE meeting from your computer or mobile device. CSE is not available on hardware.
  • Due to authentication requirements, users must be invited to join a meeting. Learn how to invite a participant to a CSE meeting.
  • Due to strong authentication requirements, participants must be invited to join a meeting. The knocking capability to allow a guest is disabled.

To protect your information, Meet always encrypts call media in transit and at rest. Call media can only be decrypted by the meeting participants and Google's data center services for Meet.

Client-side encryption adds an additional encryption layer for privacy and only shares that session key with:

  • meeting participants
  • the key service of the meeting host organization (if CSE is used with an IdP/KACL infrastructure)

With CSE, only the meeting participants can decrypt the call media while Google data centers and other service providers can’t decrypt it. CSE also encrypts call media on each participant’s browser before the data transmits to other participants.

To use CSE, you must connect Google Workspace to an external identity provider and encryption key service (IdP+KACL).​

Learn how CSE works in meetings

You can join a CSE meeting the same way you join a non-CSE meeting. For CSE meetings, participants can’t join until the host has joined. Participants that join before the host get a black screen with the words “waiting for the host to join”.

Due to the extra layer of privacy, these functions are not available in CSE meetings:

  • Abuse reporting
  • Noise cancellation
  • Recordings
  • Live streams
  • Use a phone for audio
  • Add people by phone
  • Captions
  • Polls
  • Q&A
  • Jamboard
  • Share joining info
  • Interoperability through a 3rd party gateway

Learn how to invite a participant to a CSE meeting

Due to authentication requirements, participants must be invited to join a meeting. Participants can no longer knock to join a meeting.

A participant can enter a CSE meeting if the host sends an invitation:

Create an encrypted event in Google Calendar

Important: You can only add CSE when you create an event.

  1. On your computer, go to Google Calendar.
  2. At the top left, click Create.
  3. At the top right of the event window, click Turn on encryption .
    • You may get a pop-up to authenticate with your IdP. Make sure pop-ups are allowed in your browser.
    • Tip: Always turn on CSE before you enter event details. When you turn on CSE, your event descriptions, unencrypted attachments, and Meet conference settings are reset.
  4. Add event details like titles, guests, descriptions, and attachments.
    • If you add a meeting room to your encrypted event you must join the encrypted video call from your own device, not a meeting room device.

  5. Click Save.

So you know when CSE is on, a shield appears.

Before the meeting, the shield appears:

  • Next to the “Join with Google Meet” button in a Google Calendar invite.
  • Next to the meeting on your agenda at meet.google.com or in the Meet app .
  • In a banner at the top of the green room window.

During the meeting, the shield appears at the top left hand corner of the meeting window.
