Unless I am missing something, I don't see how Eve is the story is a
Confused Deputy, in the security sense of the term as coined and explained
in Norm's paper <http://www.cis.upenn.edu/~KeyKOS/ConfusedDeputy.html>.

The "Confused Deputy" is about a threat much more specific than the general
threat of confusing a deputy. See Tyler Close's "ACLs don't" <
http://waterken.sourceforge.net/aclsdont/current.pdf> for IMO the clearest
explanation of how to think about the Confused Deputy, and what is and is
not a Confused Deputy problem. (My own Capability Myths Demolished <
http://srl.cs.jhu.edu/pubs/SRL2003-02.pdf> is also good and complementary.)
