Please see UEFI 2.3.1 specification for a description of how Authenticated variables work.

hi, experts:
I have reviewed SecurityPkg\VariableAuthenticated\Pei && VariableRuntimeDxe driver, found:
1. Variable Peim
     It's same with MdeModulePkg\Universal\Variable\Pei except it would check gEfiAuthenticatedVariableGuid in
     variable store header.
     GetVariable() function did not do any authenticated operation.
2. VariableRuntimeDxe driver
    Only SetVariable() function did authenticated operation.
 
Why not add authenticated operations in GetVariable() function?
 
best wishes,
