Abstract :
We present a variant of the protocol stack for anonymous authentication implemented in German personal identity documents. We strengthen the system by eliminating group keys - a potential target of attack for a powerful adversary aiming to undermine Restricted Identification mechanisms. We provide a mechanism of authentication that merges Chip Authentication protocol with Restricted Identification.
