Abstract
One disclosed example method includes a leader client device associated with a leader participant generating a meeting key for a video meeting joined by multiple participants. For each participant, the leader client device obtains a long-term public key and a cryptographic signature associated with the participant. The leader client device verifies the cryptographic signature of the participant based on the long-term public key and the cryptographic signature. If the verification is successful, the leader client device encrypts the meeting key for the participant using a short-term private key generated by the leader client device, a short-term public key of the participant, a meeting identifier, and a user identifier identifying the participant. The leader client device further publishes the encrypted meeting key for the participant on the meeting system. The leader client device encrypts and decrypts meeting data communicated with other participants based on the meeting key.
