Classical authentification in Quantum Key Distribution
After a brief introduction to cryptography, we will focus on the need for authentication which is the obvious requirement that prevents fraudulent incoming messages to be accepted as genuine. This topic will be discussed also in the context of Quantum Key Distribution (QKD), which is an innovative technology aiming to realize a cryptographic key exchange based on quantum physics laws. QKD has become so important in recent years since it represents a possible solution to the threat of quantum computers against most used current cryptographic schemes.
