Description:
**** PRODUCT ERROR ALERT ****
PROBLEM DESCRIPTION:
************************
3-01-2018: Status update
************************
An increase in CPU utilization occurs for AES256 security encryption during
RACROUTE VERIFY PASSWORD events in CICS.
SYMPTOMS:
CICS encounters slower VERIFY PASSWORD throughput and increased CPU usage.
IMPACT:
Increased CPU usage occurs.
CIRCUMVENTION:
Apply APARs SO00168 and SO00169 if you plan to implement AES256
encryption in CA Top Secret R16.0.
The AES256 algorithm is more secure than DES or
AES128, but by design, is more computationally intensive. Carefully review
the planning considerations before enabling AES256 security encryption.
PRODUCT(S) AFFECTED:
CA Top Secret for z/OS Version 16.0
