Test Cases for Automatic Trust Management (ATM)

These test cases can be used for verifying the correctness of an implementation of the XMPP Extension Protocol (XEP) Automatic Trust Management (ATM).

A1, A2 and A3 are devices of the XMPP account A. B1 and B2 are devices of the XMPP account B. C1 is a device of the XMPP account C. The implementation being tested runs on device A1.

Manual Authentication / Distrusting

Manual authentication / distrusting for...

Case	Result
B1's key	Authenticate / Distrust B1's key, send trust message for B1's key to own devices with authenticated keys and for keys of own devices to B1
A2's key	Authenticate / Distrust A2's key, send trust message for A2's key to all devices with authenticated keys and for keys of all devices to A2

Automatic Authentication / Distrusting

Trust message to A1 from...

B1

Case	Result
for C1's key	Discard trust message
for A2's key	Discard trust message

B1 for B2's key

Case	Result
B1's key is authenticated	Authenticate / Distrust B2's key and authenticate / distrust all keys of previous trust messages from B2
B1's key is not authenticated	Store trust data for B2's key

A2 for A3's key

Case	Result
A2's key is authenticated	Authenticate / Distrust A3's key and authenticate / distrust all keys of previous trust messages from A3
A2's key is not authenticated	Store trust data for A3's key

A2 for B1's key

Case	Result
A2's key is authenticated	Authenticate / Distrust B1's key and authenticate / distrust all keys of previous trust messages from B1
A2's key is not authenticated	Store trust data for B1's key
