Re: Implementing Elliptic Curve Cryptography on javacard

Firstly, you should check whether your card supports EC cryptography. ECC is rather dedicated to sign/verify operation on java card. Here is part of sample code which maybe helpful to you. byte[] dataToSend = new byte[64]; KeyPair ecKeyPair = new KeyPair(KeyPair.ALG_EC_FP, KeyBuilder.LENGTH_EC_FP_12...

Re: Strong authentication and JavaME apps

Java Card 3.0 Connected Edition defines Servlets as application containers. The midlet will be your client, probably communicating via JSR 177/257 to the smart card web server / Java Card 3.0.
You will need to write this web application for the card.

Re: How to write Ki and IMSI codes to card

Yes, you are right!

But firstly you have to get a real __clear__ couple (IMSI / KI). And then loading IMSI/Ki to SIM card is vendor-dependent technique.

The Ki on a SIM card when it's stored in a file can never be read by any external entity.

Re: communicate with javacard from web applet

Have you tried signing your applet with a code signing certificate? For applet code to run with higher security privileges you need to sign your code. You need to look into the jar signer tool that come with the JDK.

Re: How to enter user-ID in related form

Typically, your conversation with the smart card goes like this: App: “List the X.509 certificates (usernames and public keys) for which you know the private keys.” Card: “X.509 certificate for CN=Bob, signed by company’s Active Directory with CN=...” App: “Authenticate the user using this PIN: 1234...

Re: Store AESKey in javacard

Important security-relevant data like keys and PINs shall always be stored in designated objects from the Javacard API.
The smart card operating system will perform additional internal operations to protect the relevant values from leaking.

Re: How can I select and read EF and DF data?

You have to implement a proprietary version of CREATE FILE and the ISO versions of READ BINARY and UPDATE BINARY yourself. Usually the files consist of an (object containing a) Java Card byte array in EEPROM (just new byte[size]) for the file and meta information - maybe also in a byte[]) such as re...
