NX- And In-Core-Acceleration To Achieve Energy-Efficient Quantum-Safe Encryption For IBM i
This request is for activating in-core- or/and nested acceleration to support the advertised quantum-safe encryption also for IBM i. Other methods (as described below) are neither fast enough nor a simple solution for customers who use cloud or only a few instances.
Among encrypted protocols, a specific example for this request is a more effective tape encryption. Encrypting data with BRMS currently increases the CPU workload, latencies and backup duration. Although, IBM advertises quantum-safe encryption by using POWER nested or in-core acceleration (for AIX it can be activated via the acfo-command), it is nowhere documented that IBM i OS supports it. No option seems to decide, whether the NX or the in-core variant is used.
Only for BRMS the even more promising encryption offloading to tape drives can be used, but requires a Tape-Library-Key-Management, which would need a dedicated infrastructure of 2 servers minimum (which should be isolated and closely integrated to protected the keys). On the other hand, an application-controlled key-management is not available within BRMS (as provided by IBM Spectrum Protect and as requested in https://ibm-power-systems.ideas.ibm.com/ideas/IBMI-I-3203 ). However, with a cloud infrastructure all data (not only backup) needs to be transferred using encrypted-protocols.
If the nx- and in-core-acceleration is already provided for IBM i, this request concerns only its documentation.
