32 bits Java card vendors list

Where can I find 32 bits Java card vendors list?How about JC 2.2.2 vendors list?

There is a variety of 32-bit smart card controllers from different vendors. I did not hear of any Java Card 2.2.2 implementation yet.Might I ask why you're looking for a 32 bit Java Card?

I guess for performance and security reason, for certain application such generate RSA key on card which take 8/16 bit card 10-20 seconds. 8/16 bit card is only good for patient training or paperweight here. Or for support RSA 4096 and high bit ECC.

BTW. I am wear IC vendor for 32bit card. but which one support Java?

patient training? paperweight?

I guess you conclude that a 8 or 16 bit controller has less computing power that a 32 bit one, but the bits mean only the address bus bandwidth.

There are techniques to extend the bandwidth. The SmartMX is an 8 bit controller, and could theoretically access only 256 bytes, but e.g. JCOP41/72 on SmartMX has 72k EEPROM.

So I doubt that that a 32 bit controller is automatically faster when it comes to crypto. You need more more versatile controller (be it a crypto co-processor, higher clock rate or more RAM to store and load the intermediate values faster), which means a higher price.

Here we mix address bus bandwidth and data bus bandwidth. In general 32 bit controller will beat 8 bit controller 400% if at same clock. This not even count RISC base, more RAM, new design...

Yes, you're correct.

I hope some one at forum could help on 32 bits Java Card vendors list.

I would like share odd one;-

Axalto/Gemalto Cryptoflex .net card:

1. 32 bits

2. .net VM

3. true Java card ( if you coding at J#)

4. in market a quite long

All the rest Java card we talk here is JC (Javacard API card) card, but one could code as pure Java

I don't think this one runs Java Card, but some J2ME technlogy (CDC or CDLC): http://www.gi-de.com/pls/portal/maia.display_custom_items.DOWNLOAD_SEEALSO_FILE?p_ID=5452

NXP PROX cards are dual interface cards. Is there a NXP (or even other vendors) JCOP card that does not have contactless interface?

# 9

Yes, NXP offers card with only contact interface:- JCOP 21-72/36/18 v2.2 (VGP config 3, 72/36/18k EEPROM)- JCOP S20-10 v2.2 (VGP config 2, 10k EEPROM)- JCOP S10-10 and 10-36 v2.2 (VGP config 1, 10k/36k EEPROM)

Sorry for pulling up yet another old thread, but I'm wondering if anyone knows any JC2.2.2 vendors as of today. I've been doing a bit of googling, but I can't seem to find any.

Lillesanda at 2007-7-9 6:16:12 >

# 11

How lexdabear told me, there have been no Java Card 2.2.2 or GP 2.2.1 compliant Java Cards implemented yet.I have also been interested in any of those.Best regards,Eve

http://www.athena-scs.com/product.asp?pid=32Supports javacard 2.2.2.

# 13

Are u sure?It is only mentioned as optional... What does that suppose to mean?In the datasheet only java 2.2.1 is highlighted.Best regards,Eve

Ievaa at 2007-7-9 6:16:12 >

# 14

It means that you can get either 2.2.1 or 2.2.2 as per your requirements.

ptangia at 2007-7-9 6:16:12 >

# 15

Hmmm... quitre interesting then...But the version of GP is still 2.1.1Thanks for the information. In case u will find anything else up to date, it would be great to know.Best regards,Eve
