T7 Interface Encryption: Decommissioning of support for TLS 1.2

Eurex Circular 124/24 T7 Interface Encryption: Decommissioning of support for TLS 1.2

1.    Introduction/Details

Since the introduction of the TLS connectivity option (payload encryption) for ETI Low Frequency (LF) sessions in October 2023, Eurex has supported TLS 1.2 and TLS 1.3 in parallel.

To further enhance the security and performance of its interfaces and additionally align with the latest industry standards, Eurex will discontinue the support for TLS 1.2. The support for TLS 1.2 will be decommissioned from 14 March 2025 in the T7 Release 13.0 simulation environment and from 28 April 2025 onwards in the T7 Release 13.0 production environment. 

A list of the cipher suites supported by TLS 1.3 can be found in the Network Access Guide which is available on the Eurex website www.eurex.com under the following link:

Support > Initiatives & Releases > T7 Release 13.0 > System Documentation > Network Access

2.    Required action

Participants currently using TLS 1.2 must adapt their applications to use TLS 1.3.
