Zoom to bring end-to-end encryption to all users, including non-paying

E2E encryption is meaningless unless there is a way to prove that it is E2E, e.g. by showing us the source code of the client side and allowing us to compile it ourselves, which Signal does.

It would be super interesting if there was a way to abstract out encryption on the camera itself, where the video call software gets an encrypted video stream and its only job is to convey that stream to the other side, which decrypts it.

The hard part is sending an encrypted stream that can be programatically degraded based on available bandwidth, and still be cryptographically secure.

Sounds like a use-case for efficient homomorphic encryption.

We really need a fully homomorphic fast public key encryption. That would enable digital signing schemes that can encrypt the entire document using public key scheme (double-barrelled signing: first encrypt using private key that would be decrypted using public key, then encrypt that form using public key that would be decrypted using private key; the first (and only that one!) encryption would be homomorphic).
