Zoom - Verschluesselung (Ende-zu-Ende) nutzen/en: Unterschied zwischen den Versionen

Aktuelle Version vom 9. September 2024, 21:44 Uhr

Die deutsche Version finden Sie auf der Seite Zoom - Verschlüsselung (Ende-zu-Ende) nutzen

By default, transport encryption (similar to https) is activated for all Zoom conferences. This guarantees that the conference content is protected from strangers (hackers) during transmission between participants and Zoom servers. However, the operators of the Zoom servers can view the data. The University of Paderborn's campus license is operated by a German company (Deutsche Telekom), to which European data protection law directly applies. The US manufacturer has access to parts of Zoom, which are contractually regulated and limited, but cannot be excluded.

By activating the so-called end-to-end encryption (E2EE - end to end encryption)' in Zoom, the confidentiality of communication can be completely guaranteed. This means that neither the operator of the Zoom campus license (Deutsche Telekom) nor the manufacturer of the software (Zoom in the USA) can access the content of the communication. The disadvantage is that not all zoom functions are fully available when using E2EE and the Zoom client must currently always be used.

In addition to the content of a conference, further data called metadata (IP addresses of participants, device/hardware information, e.g. browser, name and description of the meeting, date, start, duration, number of participants) is generated. These are passed on to Zoom in the USA in every meeting, for example to better localize problems and errors and to generate usage statistics.

For conferences with confidential and personal content, such as job applications or personnel interviews, appointment procedures, senate or presidium meetings, etc., Zoom at the University of Paderborn may only be used after the organizer has considered data protection law and only with activated end-to-end encryption.

Zoom can usually be used in the standard setting for courses, meetings or public events.

Requirements for the E2EE[Bearbeiten | Quelltext bearbeiten]

Participants must have the Zoom client version 5.4.0 or newer installed on their devices.

Check encryption[Bearbeiten | Quelltext bearbeiten]

Within the meeting you can see which encryption is active by looking at the symbol at the top left.

	Check mark on green sign. Only transport encryption active. For non-confidential conferences.
	Lock on green sign. End-to-end encryption active. For confidential conferences.

Compare security codes to check if the meeting is secure. To do this, click on the green icon.

Click “Verify”.

The security codes should be the same for all participants.

+By default, transport encryption (similar to https) is activated for all Zoom conferences. This guarantees that the conference content is protected from strangers (hackers) during transmission between participants and Zoom servers. However, the operators of the Zoom servers can view the data. The University of Paderborn's campus license is operated by a German company (Deutsche Telekom), to which European data protection law directly applies. The US manufacturer has access to parts of Zoom, which are contractually regulated and limited, but cannot be excluded.
-Zoom meetings are TLS encrypted (like https). This secures the conference against third parties like hackers. The campus license of the university Paderborn is provided by a company located in Germany (Connect4Video GmbH – C4V). TLS encryption can’t secure the conversations against access of zoom or C4V. Both parties assure they don’t access the conversations but this can’t be guaranteed.
+By activating the so-called ''end-to-end encryption (E2EE - end to end encryption)''' in Zoom, the confidentiality of communication can be completely guaranteed. This means that neither the operator of the Zoom campus license (Deutsche Telekom) nor the manufacturer of the software (Zoom in the USA) can access the content of the communication. The disadvantage is that not all zoom functions are fully available when using E2EE and the Zoom client must currently always be used.
+In addition to the content of a conference, further data called metadata (IP addresses of participants, device/hardware information, e.g. browser, name and description of the meeting, date, start, duration, number of participants) is generated. These are passed on to Zoom in the USA in every meeting, for example to better localize problems and errors and to generate usage statistics.
-Confidential conversations can be held by using the end-to-end-encryption (E2EE). With this option, neither zoom nor C4V can access the content of the video conference. While using the end-to-end-encryption, not all zoom features are available. For end-to-end encrypted meetings, the Zoom client must be used. Joining the conference via browser is not possible.
+For conferences with confidential and personal content, such as job applications or personnel interviews, appointment procedures, senate or presidium meetings, etc., Zoom at the University of Paderborn may only be used after the organizer has considered data protection law and only with activated end-to-end encryption.'''
-Additional to the content of the conversations, zoom is gathering metadata. Examples are the IP address of the participants, device and hardware information, browser configuration, name and description of the meeting, date, time, duration of the meeting and number of participants. These information are available for zoom and C4V, even when the end-to-end-encryption is used. This information can be transferred to zoom USA for problem diagnosis and enhanced user experience. In case of privacy, gathering metadata must be seen critical. We recommend an evaluation if another service like BBB, Jitsi Meet, or DFNconf can be used which provides more privacy.
+Zoom can usually be used in the standard setting for courses, meetings or public events.
-We recommend the usage of zoom only for conferences with significantly more than 20 participants. For smaller groups, services with more privacy should be used, like mentioned above. For conferences in which personal data is discussed, Jitsi Meet, BBB and DFNconf should be favored.
+== Requirements for the E2EE ==
+Participants must have the Zoom client version 5.4.0 or newer installed on their devices.
-For conferences with confidential information like job interviews, appraisal interviews, appeal hearings, senate and chair conferences Zoom can only be used after a consideration of data protection laws by the host and only with activated end-to-end encryption.
+== Limitations ==
+If end-to-end encryption is activated, you currently have to do without the following Zoom functions (as of October 28, 2023):
-For courses, lectures, seminars, conventions and public events, zoom normally can be used in default settings.
