Response to GET DATA [Config] seems wrong #5

Closed laf0rge closed 3 years ago

laf0rge commented 3 years ago

I'm getting df21020808 as the response to GET DATA [Config].

That looks odd, as the spec defines the srtructure of the response as follows:

DF21 (Response-ARAM-Config-DO), containing
E5 (ARAM-Config-DO), containing
E6 (Device-Interface-Version-DO), containing
3 bytes version number e,g, 010100 for v1.1.0

The "0808" opaque binary data in the DF21 doesn't seem to make sense in the above context.

Feel free to correct me, if my understanding of the Secure Element Access Control v1.1 spec is wrong.

nevermind, I had the wrong application selected. The Applet now respons with 6a86 as it doesn't even know anything about GET DATA [Config] at all.
