elliptic curve coprocessor in JCOP
I have some JCOP41/72K cards with support to ECC.
I suppose the cards come with a coprocessor that performs the elliptic curve operations in binary fields, like reduction modulo irreducible polynomial and escalar multiplication of a point.
I've already developed a signature scheme (ECDSA) in these cards using Java Card API.
In ECDSA, the card performs all elliptic curve operations and gives the result.
These operations are perfomed by the coprocessor in a transparent way when I ask to compute a ECDSA signature.
Now I would like to develop other cryptosystems based on bilinear pairings.
So I need to perform operations like reduction modulo irreducible polynomial and escalar multiplication of a point.
Does anybody know if its possible to access the functionalities of the elliptic curve coprocessor of JCOP cards?
If its possible, how can I do this?
Thanks.
