Alibaba and T-Head (a semiconductor chip business entity of Alibaba Group) combined efforts
on the platform Yitian, so our cryptographic accelerator which is integrated in Yitian was named YCC,
the acronym for Yitian Cryptography Complex. We prefer ycc for our crypto related drivers.

Anyway, thanks for your suggestions. I will adjust in alphabetical order in next version.

Best regards,
Guanjun
