IBM Z Hardware and Operating Systems Ideas Portal


This is the public portal for all IBM Z Hardware and Operating System related offerings. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas

  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Crypto HW

Showing 12

Request to auto synch the time across all crypto adapters with the system time.

Each IBM 4768 (and other 476x series) cryptographic coprocessors maintains its own internal clock to provide timestamped logging for PCI-HSM compliance. The clock value is set for each card individually by an operator using the TKE "Set Clock" fun...

Sync CryptoExpress clock to sysplex timer

Currently the only way to set the clock on CryptoExpress hardware is to use the TKE workstation to manually set the time. This can result in: Discrepancy between different cryptographic hardware, especially when using multiple mainframe footprints...

Increase the CRL field length in TR34 ICSF services

The CRL field length in TR34 ICSF services CSNDT34B and CSNDT34D are defined with only 3500 bytes. If the CA sends a CRL more than 3500 bytes then the services will fail resulting in ATMs going out of service.

Add Certificate trust verification in CSNDDSV service

Currently the option to verify the trust of a certificate is possible only by adding the CA and Intermediate CA certificates using TKE into ICSF adaptor. This is new and overhead for the limited ICSF admin team. Add option to verify the signature ...

ChaCha20-Poly1305 for IBM Z and LinuxONE

Requesting system hardware support particularly in IBM Crypto Express features (but also in CP Assist for Cryptographic Processing, and in operating system and middleware exploiters such as z/OS System SSL) for the ChaCha stream cipher (at least t...

Crypto Hardware Adjunct Processor Assignment

Crypto Adjunct Processors (APs) are assigned to Crypto PCHIDs at Power-on Reset time. In our experience they differ across multiple z15s despite being identical in hardware configuration. Can we manually assign APs to PCHIDs even if it requires a ...

No support of TR31 Block D K1 keys with dual mode of use

ICSF does not support TR31 K1 keys of type D with mode of use B(for encrypt and decrypt). CSNBT31I service ends with cc8/rsn7e0 (incorrect rule array parameter content). This makes ICSF CCA incompatible with authorities that do not separate KEKs a...
