Java Card Reference Implementation the way to the hell...

These days I worked on bug hunting, Our java card OS platform was base on RI of C codes (Java Card Reference Implementation from sun (Oracle). Some bugs are really nightmare for the OS architecture which copy codes from RI. I suggest you to be far away from it.

Re: How to speed up RSA encryption/decryption in java card

Are there any experiences or experiment data which could be shared? As I know the Java Card Algorithm Test tool can do this thing.

Re: How to implement T=CL protocol

I am sure.You are quite right.
T=CL is block protocol, T= 1 is block protocol too. So, they are similar. You could referce to your T1 protocol implementation.

Re: .net programming for developing applet

Both Gemalto and Feitian have .net card product several years ago, but I suggest that you preferre to use javacard .
Learning java language is easy for a .net programmer.
Choosing a javacard product is feasible, a .net product may be more expensive ,lead time and less technical materials .

Re: the difference between Util.arrayCopy and Util.arrayCopyNonAtomic

I think Util.arrayCopy is equal to following the code

Code: Select all

    JCSystem.beginTransaction();
    Util.arrayCopyNonAtomic()
   JCSystem.commitTransaction();

Re: Default Selected?

No,it's your option.If you set the APPLET to default,the APPLET will be selected automatically on reset phase of card .
It you don't set the APPLET to default,you have to send SELECT APDU before use the APPLET.
