SE05X Driver

This driver enables access to the NXP SE05X secure element by using the NXP plug and trust nano.

Note

Currently this driver has only been tested on SE050.

API

The driver supports reading/writing to the SE05X's keystore and additional features like diffie-hellman key derivation and signing CSR's and verifying certificates using keys from the keystore. Refer to drivers/crypto/pnt/pnt_se05x_api.h for the API functions available and to include/nuttx/crypto/se05x.h for the ioctl commands

These tools make use of the SE05X driver (which can function as a reference project):

• The controlse app can be used to control the SE05X from NSH.
• The setest app tests all the SE05X ioctl functionality from NSH

Datasheets are available on the NXP website.
