[Spice-devel] [PATCH libcacard v2 06/35] ACA Applet
Jakub Jelen
jjelen at redhat.com
Thu Aug 2 09:43:38 UTC 2018
* The Access Control Applet is used to discover other applets
in the card, discover Access Control Rules for various opperations
and provides information about authentication mechanisms.
* The ACA provides many structures that are quite independent from
the rest of CAC so it is implemented in separate file.
* All the structures are annotated with the references to specifications
* Implements structures and access functions in ACA Applet
* Access Control Rules table
* Applet/Object Access Control Rules table
* Access Method Provider table
* Service Applet Table
(from "5.3.3.5 Get ACR APDU" of GSC-IS 2.1)
