Аннотация. The publication of the BB84 protocol by Bennett and Brassard in 1984 marks the beginning of quantum key distribution. Since then, many other protocols have been invented. Yet, BB84 keeps a privileged place in the list of existing protocols: it is the one of the most analyzed and most often implemented, including those used in commercial products. We offer the analysis of BB84 protocol. The physical implementation of the protocol is investigated. Finally, we analyze the eavesdropping strategies against BB84 and deduce the secret key rate.
