Zoom , like other similar tools, have become a fundamental part of the daily life of many users. Being able to make videoconferences, share work remotely, is very present. Everything related to the Covid-19 pandemic has brought changes of this type. However, security is still a very important factor and must always be present. From now on Zoom is going to be more secure by adding end-to-end encryption .
Zoom adds end-to-end encryption
From Zoom they just confirmed something that many users had been waiting for a long time: they will implement end-to-end encryption for everyone starting next week. This makes using this platform much more secure.
Users who use this service through the desktop client, the mobile version or from Zoom Rooms will be able to take advantage of end-to-end encryption. A greater guarantee that the conversations will be private and no one could access them.
When someone joins a meeting they will know in advance whether it is end-to-end encrypted or not. A green shield logo with a padlock will be displayed at the top left. This will indicate that we will indeed be using this new function that will now be available to everyone.
Of course, from Zoom they indicate that it is something new and that you may have a problem during the first days. For this reason, they ask that during the next 30 days users leave comments in case they notice any type of failure.
From now on, both free and paid users will be able to create end-to-end encrypted meeting rooms with up to 200 participants . It is certainly a more than considerable figure.
Keys are generated by the participants
All end-to-end encryption keys are generated by the meeting participants’ computers rather than by Zoom’s own servers, rendering all data exchanged indecipherable by this service or other third parties, with the exception of each meeting participant.
Until now, in a typical meeting, the Zoom cloud generated encryption keys and distributed them to different participants as they joined. With this new feature, the meeting host generates encryption keys and uses public key cryptography to distribute these keys to other meeting participants.
We can say that the Zoom servers become foreign relays and never see the encryption keys necessary to decrypt the content of the meeting.
Keep in mind that we have to enable this function in our account . It also has certain limitations, such as not being able to enter the room before the host, nor recording in the cloud, surveys and other functions.
In short, Zoom is now more secure for all users. Not only paying customers will be able to use end-to-end encryption, but anyone else with the free version.
