AM5728: Questions for crypto hardware accelerators and library

Part Number:AM5728

Hi,

I got a few questions from my customer about security hardware in Sitara, especially AM57x.

Q1)
Are there any hardware accelerators available for ECC(Elliptic Curve Cryptography) inside Sitara (or other TI processors)?
ECDH GF(p): 256/384 bits
ECDSA GF(p): 256/384 bits

Q2)
I know there are AES, SHA, RNG, DES and 3DES in AM57x, but there is not document which explains them in details.
Customer wants to know below features are supported or not.

AES ECB mode 128/192/256 bits
AES CBC mode 128/192/256 bits
SHA-256, SHA-384, SHA-512 Hash
SHA2-MHAC
pseudocode generation by SHA2

Q3) Do we have ECC library available for Sitara or other TI processor?

Thanks and regards,
Koichiro Tashiro
