Running Docker Swarm inside LXC

I've been using Docker Swarm inside LXC containers for a while now, and I thought that I could share my experience with you. Due to their nature, LXC containers are pretty lightweight and require very few resources if compared to virtual machines. This makes LXC ideal for development and simulation purposes. Running Docker Swarm inside LXC requires a few steps that I'm going to …

Elliptic Curve Cryptography: breaking security and a comparison with RSA

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 …

Elliptic Curve Cryptography: a gentle introduction

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 of the main technologies on which the modern web and IT world …
