Hello everyone. I have a question. I need one OS agent (windows application) sending some data to a UEFI DXE module, which will only process that data at the next boot.
I know the first thing that comes to mind in this case is to use UEFI variables, but I would like to know if you guys can share some knowledge about other possible options, which are safer than using UEFI variables. In case I use UEFI variables here I will not be that comfortable with having a variable available at boot time and runtime, which can be easily accessed from the OS. This will create the need of several controls and logic at the dxe driver to make sure the data I am receiving is reliable, it is not a replay attack and other security related scenarios. Any idea about other approaches I can follow to have this "communication channel" between OS and the BIOS (data processed at the next boot) Thanks Rafael Machado -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
