IBM Smart Card OS On A 1MB Smart Card

michaelpapet.com writes "IBM has ported/developed their Javacard smart card operating system for Sharp's 1MB smart card. Read Sharp's announcement here. Interesting features include: AES encryption; elliptical curve encryption; and 1MB of storage. Sharp's smart card package claims to be almost as small as a normal smart card package. In an industry that can considers 64K of memory a luxury, 1MB is staggering. Read Sharp's original 1MB smart card announcement here. Is this a 'Build it and they will come...' kind of solution? How small is an 'almost as small' smart card IC package?"

One "640k should be enough for anybody" joke in the title should be enough for everybody.

Re:Storage space

[John Harrison]

I work for IBM with smart cards. My team directect Sharp the the JCOP (Java Card Open Platform) operating system over a year ago. The 1MB is rewritable storage. The OS is stored in ROM. It is a simplified version of Java (the JavaCard standard) that requires very little in the way of resources.

Functionality is added to the card by securely loading JavaCard applets to the 1MB of storage. More info on JCOP can be found here.

What is this good for?

Smart cards are a great way to keep you private encryption key(s) and passwords safe, OFF your computer harddrive, and out of your computer memory.

Why? Because you the user can not know if the computer you are typing on is safe ( think spyware, malware etc... ) .

Current smartcard technology has been problimatic because you can only store tiny amounts of data on them. By tiny I mean really small, shorter than a few SMS (text based cellphone) message amount of data. ( dont forget the file allocation table takes up space...)

You also dont really store data on them, they store data for you. Smart cards are basically little computers, that will only respond with the correct password to give you your data. Pretty clever really.

Now it looks like they will be able to store much more data, like a couple 1024 bit keys, your encrypted passwords and lots of other great stuff like that.

That is what it could be used for... but I am sure everyone is going to buy them because they can save their IE Favorites, and their Email Address book on it.

The 20 Year Cycle

[Etcetera]

20 years ago, Apple was figuring out how to squeeze a graphical operating system into 128K of RAM. Permanent storage that didn't cost 5 figures was in the 400K range.

In this day of multi-gigabyte OS installs, it's refreshing to see people return to the "lean and mean" OS mentality, even if it's out of necessity. Hell, even 10 years ago, you could still install an entire installation of Mac OS 7.6 on a set of 10-12 floppies.

Those were the days. Nice to see such "hack"ish talent used again.

Here is the confusion

[GoClick]

The confusion here is that the average /.er doesn't know that a SmartCard is not a SmartMedia Card.

A SmartCard is NOT for holding pictures of your cat. It's primarily for identity verification. See
SmartCard

A SmartMedia Card IS for storing pictures of your cat or whatever else you might have. This is the large card that goes in SOME digital cameras. SmartMedia is a trademark of Toshiba. It is a flash memory format Please see
