I would like to receive a license for the Design Security Features.

Done, kindly generate your license file in Self Service Licensing Center. Only the license administrator can re-generate the license file.

Guidance: https://fpgasupport.intel.com/AlteraLicensing/license/index.html --> Licensing Center Home --> Computer and License Files --> Select a computer to generate a new license file.
