6212 device : how to work with the secure element ?

[le sage]

Hello everyone !
We've recently bought two 6212 Classic devices (not in a developer pack) & would like to inject a CARDlet (JavaCard) in the devices Secure Element. We haven't found any wiki page about this, so we have various questions :

• what is the chipset used for the NFC radio ? what is the Secure Element model ?
• we read somewhere that there was a need to "unlock" the Secure Element ; how can we do this ?
• we have already developped a CARDlet ; how can we upload it to the 6212 devices ? what kind of extra hardware do we need ?
• is there any wiki page for the 6212 (like this one dedicated to the 6131) ?

Well thanks for your help.

Hallo,

• what is the chipset used for the NFC radio ? what is the Secure Element model ?

Nokia 6212 uses the same chipset as 6131NFC: the PN512 transmission module and the SmartMX (CN072) secure element from NXP.

• we read somewhere that there was a need to "unlock" the Secure Element ; how can we do this ?

See the thread Nokia NFC Unlock Service MIDlet now available for download.

• we have already developped a CARDlet ; how can we upload it to the 6212 devices ? what kind of extra hardware do we need ?

An external ISO14443 card reader.

• is there any wiki page for the 6212 (like this one dedicated to the 6131) ?

Not that I'm aware of. But most of this page also applies to the 6212.

Thanks for your feedback Michael.

the SmartMX (CN072) secure element from NXP

OK ; funny though, I didn't find any reference of this SE on the web.

See the thread Nokia NFC Unlock Service MIDlet now available for download.

OK, this thread applies to the 6131. This documentation really should be updated to state that it is also effective for the 6212, because it isn't mentioned anyhere on the nokia.com website.

I guess this answers most of my questions. I'll open other threads should I have others.
Thanks for your help.

Hallo,

Ok, the full product name is of course P5CN072. Short form spec is here:
http://www.nxp.com/acrobat_download2.../SFS107710.pdf

And NXP's product page for the SmartMX family is here:
http://www.nxp.com/products/identifi...ers/index.html

OK, this thread applies to the 6131. This documentation really should be updated to state that it is also effective for the 6212, because it isn't mentioned anyhere on the nokia.com website.

Honestly, I have not tried unlocking a 6212, I would just expect it to work the same way. Unless, of course, the SE has already been personalized (e.g. by a TSM or the MNO that sold the phone).

Oh, now I get it.
Well, I'll try unlocking the 6212 I have, I'll keep you updated on the result.
Thanks for your help Michael.

Ooops, forgot to ask :
Does it come with any JCOP version embedded ? I has a look at various PDF files on the web about the P5CN072 chip, none said anything about the JCOP OS being provided. I guess it depends on the manufacturer's choice.
As for the Nokia 6212, what was chosen ?
Also, which JavaCard version is supported by the chip ?
Thanks for your help.

Again, I would expect the information on the wiki page to also apply to the 6212. But that's just a wild guess.

Jop, the 6212 contains the same secure element as the 6313 (a G&D Smartcard with JC OS 2.2.1, Globalplatfrom 2.1.1, no AES support). For accessing the mifare section form the Cardlets a special Library from G&D is required.

So I'm lost.
Is it a NXP P5CN072 chipset or & G1D chipset ? If it's a G&D, is there any possibility to get the reference in order to retrieve more documentation (e.g. the crypto algorithms supported, etc.) ?
I've never heard of the Nokia 6313. Is it the one that was cancelled ?
Thanks for your help geri-m.

[geri-m]

the chip (= hardward) is from NXP. die OS (= software) comes from G&D. Regarding the 6313 - it was a typo. should be 6131.

the is no detailed specification of the OS for developers, as it is compliant to JC 2.2.1 and GP 2.1.1. The "activation" of the cryptos depends on the customer of G&D. so you have to try ourself. but as far as I know, AES doesn't wor. RSA works only for signing, not encryption. But I haven't been working with the phone for quite some time now.

Thanks for this information Gerald.
Apparently, the method used in the 6131 actually seems to be the same for the 6212, see Nokia 6212: Unlocking the Secure Element.

So I managed to unlock my 6212 Classic device secure element with the regular unlocking MIDlet.

Hello,

The service we used for unlock the secure element is Nokia NFC Unlock Service MIDlet but, it never ends because appear the following messages:

"The process of unlocking the secure element was not completed". "Source HTTP Post Failed".

We think that is the connection to the 3G (or GPRS) and we try this:

Preferred access point: internet.comcel.com.co
"internet" settings from Comcel MMS: Single-shot WEB Comcel 3GSM.

Also we try that with Movistar that is annother 3G Colombia provider.

Could someone please help me with this troubles?

I use a serial reader Feig CPR M02 and Nokia 6212 unlocked.
If i use gpshell, helloworld.cap to install, i get:
C:\work>GPShell.exe helloworld.txt
mode_211
enable_trace
establish_context
card_connect
The authentication work (9000) but not the installation.
