Compression with Java/Smart Cards

I am a Software Development Student. I am currently researching the area of data ZIP compression in conjunction with Java/Smart cards. Just wondering if anyone has come across a similar project and if so where?
Thanks.

We can't deal with real compression, as you known the jcvm is composed of the converter and the jcre
the compression is related to the converter.jar
There are many ways to produce compressed code compared to an original not optimisez code.
Real comresion is not really possible on a such support, the processor is not enought fast. In my mind, the only compression possible can be the rle. Not very brilliant if it is not used for images...
(sorry for my english writting...)

Need a recommendation about java smart card and a reader

I've been posting some message in this forum and others and haven't gotten a clear response.
I want to experiment with java smart card technology.
From what I gathered, Gemplus is a leading company in this field so I thought about buying a smart card reader from it and a java smart card.
I thought about buying the "USB Smart Card Reader/Writer Plug n Play (GemPC430)" reader which costs 69$.
Is this a reasonable price?
I need an answer from someone with experience using it.
Now then, which one should I buy?
I only want to do smart card to desktop application interaction without anything on the web (e-commerce or anything to do with encryption).
I can buy 5 "GS2.2 Standard Crypto GPK8000su512 RED"
cards which cost 87.50$
THATS A LOT OF MONEY!!!!
Are all java smart cards that expensive?
There is a list of other cards on their site but I haven't been able to locate their price and don't know which to buy.
Finally, there is the "Kit, GemSAFE Enterprise Workstation 2.21 Standard Cryptography Serial Port Reader" which as I read consists a GPK8000 card.
Is this card a java card?
Or do I need to buy the reader and java card seperately.
Any help and insight would be greatly appreciated.
Thanks.

I've looked closely at the Cyberflex 32K cards + SDK from Schlumberger.
My criteria was:
* Javacard 2.1 support
* visa open support (or whatever it is called now)
* complete sdk (develop, test, deploy)
* exportable
* upgradable
* customer support
I tried to get someone from Gemplus to contact me, but was unable to ever get even an
email response.
Schlumberger, on the other hand, won me over with the quick responses over email.
They offer fairly inexpensive upgrades after you buy the product, and technical support
is free.
For simple experimentation, you can get the JavaCard SDK for free. At JavaOne, several
years ago, they were giving away JavaRings with Card Readers (which presumably
means these are cheap to buy) from SCM or some company in Texas. You might
try to get one of these. They don't have much memory, but are an interesting twist
on the Java Card thing.
If you want to dive in, the Smart Card SDK from Schlumberger will run you about $499.
This includes the reader, 5 cards, and the SDK. Likewise, Metrowerks puts out an
IDE for Java Card which runs about $1200, and may be available as a bundle from
vendors like Schlumberger.

Help needed in learning the basics of Java Smart Card and implementation?

Hello every body,
I am trying to develop the applications on java contactless smart cards technology.
Can any body give me the details like how to start?
What are the required softwares and installation procedure and path settings and etc.?
I am the beginner in java smart card application development.
plz help me out

Dear Friend,
I would advice to divide learning into two main parts: JavaCard technology and contactless RFID cards. For JavaCard technology you can find useful articles on Sun web-site (developers.sun.com/mobility/javacard/articles/javacard1/). For contactless RFID you can find few useful books at Amazon. Regarding software you need JC development kit. How to install it there is an instrunction in JCDK user guide.
If it is not a secret what a javacard contactless card you are going to use in your work?
Yours
Dmitri

How to sign PDF with a smart card or USB token in C# through IAC ?

Hi,
My goal is to apply a certification signature (MDP) to a PDF document with a smart card (Belgium identity card) from a C# application.
I start Acrobat through IAC.
The JavaScript object apparently can only sign with PKCS12 file (.pfx)...
To sign a PDF with a smart card I need to develop a plug-in if I am right?
The samples in the SDK are to get a certificate from the windows certificate store or to write a Third party handler.
I already get the certificate context (an HCRYPPROV object from windows certificate store)
How can I create a signature field but mostly sign it? With DigSig I guess, but I’m lost in the API… does
I have to use DigSigSignDoc ?
Syntax : void DigSigSignDoc(PDDoc pdDoc, CosObj sigField, ASAtom filterKey)
The filterKey value for the windows certificate store is “Adobe.PPKMS” but how can I choose my certificate?
I also have to build a signature reference dictionary i guess?
What does i have to do and in which order? I can't find any documentation on this.
There is a more simple way?
Thank you,
Goffin
Fabian

Hi,
-download the JDK sample "sdkAddSignature.js"
-change the sign methode like this :
Sign = app.trustedFunction (
    function( sigField, DigSigHandlerName )
   try {
   app.beginPriv();
   //the diSigHandler is "Adobe.PPKLite"
   var myEngine = security.getHandler(DigSigHandlerName);
   var ids = myEngine.digitalIDs;
   //choose an id which is installed in the microsoft store
var oCert = ids.certs[3];
// for (var i=0; i<ids.certs.length; i++)
// console.println("certificat n°"+ i + " " +ids.certs[i]);
var oParams = {cPassword:"0000" , oEndUserSignCert:oCert }
if(myEngine.login({cPassword:"0000",oParams:oParams,bUI:false}))
   console.println("OK");
else
   console.println("Error");
console.println("sigfield :" + sigField);
sigField.signatureSign({oSig: myEngine,oInfo: { password: "0000",reason: ACROSDK.sigReason,location: ACROSDK.sigLocation,contactInfo: ACROSDK.sigContactInfo}});
app.endPriv
   } catch (e) {
   console.println("An error occurred: " + e);
-perform some test using the javascript debugger
-and finally use IAC to execute the script

41N3004 compatibility with v2 smart cards

Programming multiple smart cards with multiple smart card readers in a PC causes a PCSCException in a smart card that is in progress

Hi,
I develop a Java code using smartcardio API to program a smart card. My GUI allows to add at most 5 smart card readers that will wait for card present, then do authentication and program the smart card with an application, then wait for card removal. This is a separate thread running in a loop for each smart card reader added as programmer.
The problem occurs when a certain smart card is in progress and I inserted another smart card to another smart card reader. Both smart card reader halts and throw sun.security.smartcardio.PCSCException: Unknown error 0x8010002f.
I also observed that every time there is an attempt to insert/remove a smart card in the smart card reader that is connected to the USB port would cause the programming in progress to be interrupted and throw the PCSCException.
These are some exceptions I got during my testing:
sun.security.smartcardio.PCSCException: Unknown error 0x8010002f
at sun.security.smartcardio.PCSC.SCardTransmit(Native Method)
at sun.security.smartcardio.ChannelImpl.doTransmit(ChannelImpl.java:171)
java.lang.Exception: Loader Record Failed: 6E | 0 //Sometimes I got this return code SW1 0x6E SW2 0x00 which means an APDU with an invalid 'CLA' bytes was received. I had check the command before it was sent and it was correct.
Help me understand this issue. I think the CardTerminal.isCardPresent(), CardTerminal.waitForCardPresent(0), and CardTerminal.waitForCardAbsent(0) cause this issue that CardChannel.transmit(apduCommand) is interrupted or the smart card insertion/removal causes the CardChannel.transmit(apduCommand) is interrupted.
Regards,
Knivez

Hi,
when you work with one smartcard reader only usually you address the slot -1 that means "the first found".
But to deal with multiple readers you have to use slots of course since one reader will be slot 0, next reader will be slot 1 and so on...
So a credential object will be identified on a system by a couple
<slot,alias>
After that, the way to address slots (I mean the syntax) depends on the classes you are using...

Proxy to use SATSA (or apdutool) with real smart-card

Hi!
I tried to communicate with smart card applet emulated in cref (jcwde also) from midlet via SATSA. But java card development kit includes only stub classes for javacardx.crypto - so I cannot even emulate applet which uses crypto though I can install it on real java card where it works well.
So, I've written proxy which acts in place of cref (or jcwde), receives APDU from SATSA and forwards them to applet on real smart card. It is in alpha stage but does job for me.
Is anyone else interested in it?
I started registration of project on sourceforge to make it publicly available.

the above problem is solved now. i am able to run WTK satsademo now..
but the problem is that the eeprom image which i created using java card development kit is not working with WTK emulator..
is this because of that protocol difference problem..
i have downloaded ur proxy application but the problem is that i hv to simulate every thing..
so is this proxy can be used to forward request to the java card emulator instead of the real card applet?
plz help me....

Logon with Virtual Smart Card Breaks Run As Administrator

I've been testing the Virtual Smart Card (VSC) capability on a Surface Pro 2 and Dell Latitude E7240.
This may be by design however, I have noticed that if I login using the VSC I am unable to use "Run As Administrator" functionality - for example:
Command Prompt from Start Screen
Task Manager
I'm prompted for a username / password or the VSC PIN.
In my environment the Administrative user does not have a VSC, so it is a username/password. When using Run As Administrator I'm therefore always entering a username and password.
Once the credentials are entered the prompt goes away but the application never runs.
If I lock/unlock the session and login using username/password for the non-admin user, instead of the VSC and PIN, I am able to elevate using Run As.
I have noticed that I can use the workaround as specified in this article:
http://support.microsoft.com/kb/2013976
To work around this issue, start the application using the Run as different user right-click context menu option and select the smart card reader of choice.
Click Start, select Programs, and locate the shortcut item in the Programs menu or the application folder for the application you want to run
Hold down the SHIFT key while you right-click the shortcut item, and select Run as different user.
Enter the username, password and the domain name or choose a smart card logon.
Seems a little odd... maybe I am missing something. If anyone can assist that would be great.
Thanks, Chris

Leopard compatible with Verizon Smart Card?

I am new at all this, but when I am trying to install Leopard on my MacBook Pro and I am on the set up assistant, it is asking what internet connection I have. I use the Verizon Smart Card and that isn't one of the options to choose. Am I still able to install it?

Yes, it is.

Problem with sle4428 smart card ... PLZ help me!

hi everyone
I must use sle4428 .but I have problem with reading and writing on it!
when i send my write ADPU command to card it response with 90 00 which means that it write on the card correctly(at least that's what i think it should mean!)
but when i send my read ADPU command it doesn't read the right thing although it response with 90 00 !
these are my write and read commands:
---------------------------------- Connect ----------------------------------
con
Connect (OK) : Command executed correctly
---------------------------------- Get ART----------------------------------
pon
Power On (OK) : Command executed correctly
DATA = 3B00
---------------------------------- Write Command----------------------------------
apdu ffd1001b01cc
APDU (OK) : Command executed correctly
SW1 SW2 : 90 00
---------------------------------- Read Command----------------------------------
apdu ffb2001b01
APDU (OK) : Command executed correctly
DATA
0000 FF
SW1 SW2 : 90 00
as you can see I write cc in that spesefic address but when i read that address the card returned FF. (It always returns this value.)
I'll appreciate any help

hi shili
you must verify pin, and then write to card.
use this command for verifying pin[present_code_memory_card]:
FF 20 00 00 02 FFFF
FFFF is default pin.
if correct code has been presented to to the card,
in response message error counter is FF [ first bytes of response].
use this command for writing 5152 to address 00aa:
FF D0 00 AA 02 5152
read command :
FF B2 00 AA
in each command, set Le to appropriate value.
best regards,

ACS with CAC/Smart Card Authentication

I have configured ACS 5.1 to authenticate a wireless user via EAP-TLS using the predefined Certificate Authentication Profile within ACS, but I don't understand how it is successfuly authenticating users. Is it simply trusting any user that presents a certificate signed by the root certificate I imported into the ACS certificate authority?
Thanks.

Signing with Smart Card (PKCS#11)

I'm trying to sign my .jar with ActivCard smart card and jarsigner.exe, but I got NullPointerException. I have succeeded to get list of certificates present on smart card. Is there better PKCS#11 provider then sun.security.pkcs11.SunPKCS11?

I receive the following error message when trying to sing a jar file using a PKI card:
jarsigner: Certificate chain not found for: Random. Random must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.This is the command line:
"C:\Program Files\Java\jdk1.5.0_04\bin\jarsigner" -keystore NONE -storetype PKCS11 -signedjar D:\Work_Java\Random\sRandom.jar -verbose D:\Work_Java\Random\Random.jar RandomWhat does this mean?

Smart Card application with EJB?

Hallo
I have the following problem:
I have to write an application which should be accessible from the internet. The whole application has to be on the server. Every user who wants to get access to the application has to insert a smartcard into the Reader who is installed on his local system. The application has to read some information (username or password for example) from the card and to prove if the user is allowed to start the Application.
Does anybody has an idea how to realize this? Is it possible to realize this with EJB or do i have to use an other technology?
Thanks for your answers

Well i did not use the java smart card technology. I used the Java native interface to implement the classes who have to read from the card. I got an api dll from the producer of the smart card. So i used the Java native interface to realize the logic of the smartcard application. This part of my programm is written in c++. The problem is that the whole programm is on a server but for getting access to the smartcard reader the dll s (the api dll from the producer and my dll for the jni) have to been installed on every client......
You said that i have to write a swing client who picks the information from the smartcard and sends it afterwards to the enterprise system. Is there no other possibility to solve this problem without writing a swing client ?

Smart Card Problem with AnyConnect over RDP

Hello,
For ASA 5545, v-8.6(1)2 and AnyConnect v-3.1.0165, I'm trying to start an AnyConnect client tunnel on a remote RDP (both ends Windows 7) machine and am having problems. The RDP is configured to proxy smart card devices which generally works fine. I'm using current SafeNet eToken with current client software. When I start AnyConnect from client machines (no RDP), the tunnel opens with no problem using the smart card. When I try to start the tunnel on the remote machine via RDP, I'm prompted for cert selection and smart card PIN, but get a popup from AnyConnect: 'VPN connection terminated, smart card removed from reader'. When I try to start the tunnel via RDP but use the ASA web server to start, the tunnel starts up fine with the smart card.
For the problem condition, the Windows event log on the remote RDP machine shows 3 entires (see below) wrt acvpnagent show smart card removal errors but the USB device is always inserted. Also, in investigating, I changed the client profile 'server list' config to SSL instead of IPSec. Same failure but the popup does not show.
VPN connection terminated, Smartcard removed from reader.
Description: VPNMGR_ERROR_SMARTCARD_REMOVED:A smartcard required for the connection has been removed
Thanks in advance for any assistance.
Mike

This can be resolved by going to services and disabling Smart card
