SGX_ERROR_SERVICE_INVALID_PRIVILEGE error

[Rashmik]

Have a simple java application that uses SGX to fetch key, encrypt decrypt bytes.  Upon running the jar, I run into SGX_ERROR_SERVICE_INVALID_PRIVILEGE error.

Have the user as part of sgx_prv group and have run application as root as well, still get the same error.

The server uses in-kernel driver.

Weird thing is that the same functionality provide by my sample Golang application works without any error.

It's recommended to install the Out-Of-Tree Driver.

The OOT Driver is recommended for use on platforms that do not support or are not configured for Flexible Launch Control.

You may refer to this documentation (Out-Of-Tree Driver section) for further details.

Cordially,
