ECC Encryption and Decryption

Post by bigWhite » Mon Jan 23, 2017 9:38 pm

In this book <Guide to Elliptic Curve Cryptography>, i found the ECC encryption and decryption algorithm.
How can i use it on JavaCard platform?
Thanks!

There is already such a topic which you can find by simply use the search features on the top right hand corner if you actually tried to do a search. The search is pretty user friendly and extensive.

Thank you friend.
I already seen this example.
But that is only sign and verify, no encryption/decryption for ECC. And the JavaCard API didn't implement the algorithm.

To be more precise, you want the ECDH function and not the ECDSA function right ?

Is the ECC encryption/decryption faster and more secure than RSA encryption/decryption?
sense and simplicity

Really depends on the card especially if it support hardware ECC accelerators or not. The JCAlgTest suite should show the speed of the ECC and RSA on tested cards these days.
