Let's Encrypt (the free, automated and open certificate authority) has just announced its launch schedule. According to it, certificates will be released to the public starting from the week of September 14, 2015.
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 mathematical proofs for the complexity of the discrete logarithm …
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.
