  1. Re: Info on Authenticating with the Secure Element

    AFAIK you cannot use a regular USB cable. The only way to interact with the secure element is via an external card reader, or through a signed midlet.

    <reader name> is simply how the card reader...

    Re: Card Emulation Mode

    Yes, accessing the internal MiFare card from a midlet requires the midlet to be signed. Accessing the internal MiFare card from an external card reader just requires the SE to be unlocked. - Well,...

    Re: About CAs or how can i avoid it

    You cannot self-sign as there is no way to install your own CA into a Series 40 nokia phone (of which the 6131 is). IIRC they are ~$400 PA for a code-signing cert.

    Re: About CAs or how can i avoid it

    I don't fully understand what you said, however you don't need a certificate to install into the SE. You do however need to know the keys for the SE.

    You need a code signing certificate to sign...

    Use JCOP, then you can simply use the Install button.

    Re: Getting started, a slew of basic questions

    You can have an external card auto-start a midlet installed into the phone. I don't believe you can have an external card do anything to the secure element, only an external reader can.

    The secure...

    I'll make an attempt at answering some of your questions ...

    The applications you write for running on the phone that access the contactless reader are Java Midlets which are installed into the...

    Re: Library talking to MiFare card

    Yes, if you include the some of the JAR files from the Nokia SDK into your desktop Java IDE you should be able to make use of them. The only ones that won't work are the ones that talk to the card...

    Re: Library talking to MiFare card

    At the time I did that, it was still firmware 3.1 so the MAD was not available via the phone. With the APIs associated with the new firmware it may be possible to access this.

    On Linux, in Java, I open a connection to the reader and wait until a card is presented (PCSC). I then generate APDUs to authenticate and read from the card etc. The response I get back is passed to...

    There are various posts over the internet regarding adding additional root CAs to a series 40 phone. They all conclude that it is not possible.

    Re: Reset the SE or the ME via the midlet

    I was using the term 'booting' as this is what Ebross used. As I said, I don't know the specifics and was working on presumptions ... hope I didn't cause too much confusion.

    It is possible (and I believe the default state) to be prompted whenever the secure element is to be activated. If you move the phone to a powered cardreader (regardless of what the reader may try...

    Re: Reset the SE or the ME via the midlet

    I've not done much with javacards, so don't know about that ... however as the SE is to javacard specs, however you do it with a real card you should be able to do the same with the SE.

    What do you mean by reset the secure element?

    As long as you get a code signing certificate from a provider who has a root CA in the phone then you can run code to access the secure element. It won't make any difference to Nokia which you use,...

    Re: MFStandardExample problem

    This is because your midlet isn't signed. Without a signed midlet you will be unable to access any part of the secure element.
  24. Re: External Reader talking to 6131 Internal MiFare

    Yes, it just worked for me ... I did need to unplug & replug the card reader but after that the sample tool provided with the API detected the card as a MiFare 4k
  25. Re: Wrong data to internal 4k on block 3 of one of sector

    The secure element works EXACTLY like a MiFare card, so if there is no way to undo this on a real MiFare (I don't think there is) then there is no way to undo it on the 6131.
