Hi
I have litle bit problem with your description
On card side:
IV=e(RndA+RndB) I dont have this value. I have only e(RndA+RndB').If I have to use IV=e(RndA+RndB) what is vector for encrypt?
And this vector is array with length 16?
I thing my problem is in last step and IV on reader side.Maybe I use wrong vector.
I send you image with my implementation and which IV I used for each steps.
Thx.
