I would like to inquire if there is any Method to achieve the following:
There is a list $L$ of $n$ entities that are allowed to perform a certain action. $L$ is cryptographically signed by some authority, so nobody can change it without detection. Now everybody (icluding everyone of the $n$ entities) should be able to grab a copy of $L$ and mirror it.
Is there any method one can devise a scheme, where everyone who holds a copy of $L$ can authenticate one of the $n$ entities. (for Example with a blind signature, or similar), without giving the mirroring Person the power to authenticate someone, who is not part of $L$.
Example: Some authority releases $L = [Alice,Bob,Charlie]$. Now $Dennis$ takes a copy of $L$. How can I assure, that $Dennis$ can authenticate $Alice$ but not $Eve$?
