Common Report Engine (CRE) security upgrade – connectivity testing

Release date: 15 Jan 2019

005/2019 Common Report Engine (CRE) security upgrade – connectivity testing

In order to ensure reliable and secure communication with the infrastructure of the Common Report Engine (CRE), the SSH Key Exchange Algorithms, Ciphers and MACs have been updated accordingly.

In this circular, the supported versions of Key Exchange Algorithms, Ciphers and MACs are listed. These versions can be used and tested immediately to establish a successful connection to the CRE.

Please be aware that outdated Key Exchange Algorithms, Ciphers
and MACs, i.e. which are not listed in this circular, will be decommissioned with effect from 10 March 2019.

Therefore, we would like to encourage our Trading Participants to review and adapt their IT systems accordingly before 10 March 2019, in order to ensure a smooth transition when the decommissioning takes place.

To ensure a smooth transition, Deutsche Börse is offering an additional test connection to the CRE, which offers the same security suites as the CRE server on the cut-over date on 10 March 2019.
