Zoom Video Conferencing App, Update for Security Enhancements, GCM Encryption

Zoom Video Conferencing App: Video conferencing provider Zoom Aims to strengthen the encryption of video calls hosted by paying clients and institutions such as schools, but not by users of its free consumer accounts, a company official said. The support for enhanced GCM encryption was added with Zoom 5.0 in April and this will be implemented system-wide from May 30.

With Zoom 5.0 new update, support for AES 256-bit GCM encryption was added. 256-bit encryption is much stronger than 128-bit as a bigger key size. It has a higher chance of remaining secure. This means that if someone were to attempt to hack encrypted data, AES 256-bit encrypted data would take significantly longer to crack. A new icon which is green in color (encryption shield icon) will also be visible from 30, May 2020 indicating that enhanced GCM encryption is enabled.
