I wonder if J3H145 card support SCP03? I have already have the sample, but now it supports SCP02.
Is there any method to switch to SCP03.

Thanks, But how can I get the card memory size?

Is there any way to find out how much memory size has my applet taken up?
can anyone help me ?

Thanks for your help indeed. You save my day.

Thank you for your thorough answer. So in your opinion, among all the algorithms which algorithm is the securest?

It's me again. I still have a basic question that need your help. I learned that a digital signature is a mathematical scheme to guarantee message security . Does the Signature do an unique Sign for each transaction? Shall the data be encrypted and decrypted with the same Signature?

Are you trying to use the SCP02/03 and trying to find their session keys ? What kind of session keys are you trying to find ? You need to put more detail into your question as it's too abstract for us to know how to reply your question. Sorry, I was just getting started with implementing Encryption...

Can I create session key in the Java Card 2.2.2?

Squli

Symmetric algorithm use the same session key to encrypte and decrypte data. The session key is generated dynamically and uniquely for each time transaction. So, What exactly is session key ? pls help me regarding this.
