Hello Sebastian,
did you do some followup on this idea?
we are using the Nexus with an extra NFC sticker at the battery but we like
to be able to read external tags too (Mifare Classic/Desfire)
or did someone else did some devellopment on this?
regards
Piet

Another idea I have, is to use a RFID card/tag compatible with Nexus S
which contains such a secure element and has some sort of Challenge-
response scheme. Is the tag reader always active, or is it only active
when a app "requests" it active?
Then I could just put the secure tag behind the batter

Also found some on the internet, about Nexus S having a PN65N which
according to sources of the internet, is a SmartMX security chip
combined with a NFC chip.
Any ideas on how to use this security chip? Eg writing data
(generating/writing RSA keys or writing symmetric keys) into the chip,
extracti
The keys should survive a compromise which consist of both rooting and
cloning a device.
Eg, If I leave my device on a table in a train, and one year later,
finds my device again, I should be sure that my keys are not
compromised. (If a adversial *uses* my key does'nt matter).
In other words, If I
Your options are:
Use an encrypted keystore

The closes thing I did to this was straight up Javascript AES encryption of
the Session_storage keys.
