LPC55S69: HASHCRYPT and AES-GSM

Hello !

 

I can see HASHCRYPT is not supports AES-GSM directly.

 

And in ksdk_mbedtls_config only alternatives defined for 

 

#if defined(MBEDTLS_FREESCALE_HASHCRYPT_AES)
#define MBEDTLS_AES_CRYPT_CBC_ALT
#define MBEDTLS_AES_CRYPT_CTR_ALT
#endif

 

But it is not so clear if some hybrid model can be utilized and HW accelerator partially in use ?

 

Could you confirm that current AES-GSM implementation is done by pure SW ?

 

Regards,

Eugene
