Compute operations with big values in JavaCard?

Post by wintstar » Tue Dec 15, 2015 2:05 am

I am trying to write a javacard applet which will process the compute operations (addition and a multiplication) with big values.

Because my card version is JC2.2.2, the big values can only be represented by an array of bytes or an array of shorts.

If I define how to do a multiplication and an addition of two arrays, could I develop an applet to do what I want ?
Is there any demo code?
