I am working on smart cards and especially a Java card . I faced many difficulties to develop my own cryptographic algorithm due to the limited API: there is no access to the crypto process for calculating the addition of points on the EC or modular multiplication, for example.
I heard that MULTOS is more flexible for this feature, is that true? Could you mention some examples of crypto processor functions (modular arithmetic, adding elliptic curves, etc.), Available in the MULTOS API, but not available on the Java map?
