QAT Gen6 also gains wireless mode support and an anti-rollback security feature to prevent firmware downgrade attacks. Additional crypto subsystem changes include TI DTHEv2 driver support for CTR/GCM/CCM AES algorithms, removal of legacy DES/3DES CPU acceleration, and removal of unused SIMD SKCIPHER support. ## Full article daily.dev links to this article rather than hosting it.
