Design and develop BB84 protocol

Abstract

Since ancient times, methods of coding information have been used to ensure confidentiality. Roman Emperor Caesar proposed among the first a substitution-based encryption algorithm. Today it is called Caesar Cipher. The idea was simple, replacing the letters according to a key initially established and known to both the source and the recipient. Today, however, the amount of information is growing exponentially, computers have made available to mankind the computing power as it never was before. Therefore, the confidentiality of the data has been attacked.
