CHESS Hardware Security Modules (HSM) Encryption device upgrade Scheduled for Saturday 25 November 2023

To contribute to the continued supportability of the CHESS service, the CHESS HSM Encryption device will be upgraded on the CHESS Production primary and secondary environments on Saturday 25 November 2023. There will be no functional change associated with the upgrade, and CHESS Users’ application and connectivity details will remain unchanged.

Participants’ connectivity in the CHESS production environment is setup with mandatory encryption, however participants’ connectivity in the three CHESS external test environments is currently setup with optional encryption.  To prepare for the CHESS HSM Encryption device upgrade in production, encryption into the CHESS external test environments will be set to ‘mandatory’ from the following dates:

• Saturday 29 July 2023 - XP1 [Port 4207] and XP2 [Port 4210]
  
• Saturday 23 September 2023 – RTE [Port 4206]
  

CHESS users may need to enable encryption in their test systems to support the transition to mandatory encryption on the CHESS external test environments. CHESS users are encouraged to contact their IT/System vendor to enable encryption on their behalf.

Access to the external test environments will require the use of the general testing encryption keys. The CHESS external test environment encryption keys can be located in your current CHESS test kit, alternatively please contact Equity Operations for assistance. Following the upgrade of the encryption device CHESS users can continue with their planned testing in the CHESS external test environments.

Participants’ connectivity into the three CHESS external test environments will revert back to ‘optional’ encryption following the implementation of the HSM Encryption device upgrade into CHESS production on Saturday 25 November 2023.

Below are the key dates for this upgrade.

What do I need to do by when?

To enable encryption into the CHESS external test environments, CHESS Users may need to contact their IT/System vendor for assistance.

Encryption keys for your test environment can be located in your current test kit, alternatively please contact Equity Operations for assistance.
