AES-GCM

[qwerty1996]

what is NXP’s recommended architecture on i.MX8M Plus to achieve AES-GCM with hardware-protected keys? If direct black-key use with AES-GCM isn’t supported, what is NXP’s recommended pattern to provide the same security property while maintaining high-performance AES-GCM?

Hello,

I found a good reference for the black key at https://gitlab.navisincontrol.com/varigit/linux-imx/-/blob/lf-5.15.y_var01/drivers/crypto/caam/caamk... , and for AES-GCM at https://github.com/nxp-mcuxpresso/mcux-sdk/blob/main/drivers/caam/fsl_caam.c
