This post is the fourth and last in the series ECC: a gentle introduction. In the last post we have seen two algorithms, ECDH and ECDSA, and we have seen how the discrete logarithm problem for elliptic curves plays an important role for their security. But, if you remember, we said that we have no...

This post is the third in the series ECC: a gentle introduction. In the previous posts, we have seen what an elliptic curve is and we have defined a group law in order to do some math with the points of elliptic curves. Then we have restricted elliptic curves to finite fields of integers modulo a...

Those of you who know what public-key cryptography is may have already heard of ECC, ECDH or ECDSA. The first is an acronym for Elliptic Curve Cryptography, the others are names for algorithms based on it. Today, we can find elliptic curves cryptosystems in TLS, PGP and SSH, which are just three...
