Hello Somchid,
for SNC there is a Secure Login Library 2.0 (SAP NW Single Sign On 2.0) for HP-UX-IA 11.31. It depends on the OS system and not to the ABAP Kernel Version.
be aware:
There are some incompatibilities with the SECUDE Library because of Name Schemas etc, and need some special configurations.
best regards
Alexander Gimbel.
