In the previous parts of this blog series I introduced the general principle of asymmetric cryptography and explained how one can use the Diffie-Hellman Key Exchange to establish a shared secret among multiple parties over an unsecure channel. In this blog I will introduce you to Elliptic Curve Cryptography (ECC), which allows using shorter keys than, for example, the DH key exchange or the RSA cryptosystem. READ MORE

In the first part of this blog series I explained the drawbacks of symmetric encryption/decryption and how asymmetric cryptography can help to overcome these deficiencies. In this blog I will explain how and why it works so well and will describe how two parties can exchange a shared secret key using the Diffie-Hellman Key Exchange algorithm.
