Eurex Clearing FIXML Interface: Changes to supported SSL cipher suites

Due to a security upgrade of Eurex Clearing’s AMQP brokers, some older and less secure SSL cipher suites will no longer be supported. This includes especially the cipher suites based on the RC2 algorithm and on the 40-bit strong RC4 algorithm. Following SSL cipher suites are recommended and supported:

  • TLS_RSA_WITH_AES_256_CBC_SHA
  • TLS_RSA_WITH_AES_128_CBC_SHA
  • SSL_RSA_WITH_3DES_EDE_CBC_SHA

Support for other cipher suites is not guaranteed or tested.

The update is already available in Simulation for testing. It will be available in Production as of start of business on 15 September 2014. This change affects only Members using the AMQP connectivity. Members using the WebSphere MQ connectivity are not affected.

Volumes A and E of the Eurex Clearing Messaging Interface Connectivity documentation have been updated accordingly and can be found on the Eurex Clearing website www.eurexclearing.comunder the following link:
