Dear Xetra and Börse Frankfurt Participants,

With this Newsflash, we would like to remind you about the final upcoming mandatory implementation dates for ETI encryption regarding the usage of interface encryption. 

Please note that the next encryption milestone is the mandatory usage of payload or password encryption for ETI LF sessions and the usage of password encryption for ETI HF sessions, initiated from within the Equinix FR2 co-location facility, will become mandatory on 24 November 2023 for simulation.

The usage of payload or password encryption for ETI LF sessions and the usage of password encryption for ETI HF sessions, which are initiated from within the Equinix FR2 co-location facility, will become mandatory in production on 11 December 2023. 

Deutsche Börse has provided a sample implementation of the ETI password encryption on the client side. The script can be downloaded from the Xetra website under the following link:
