ABSTRACT. Modern quantum technologies of information security consist of following direction:quantum key distribution, quantum secure direct communication, quantum steganography, quantum secret sharing, quantum stream cipher quantum digital signature etc. In practice quantum key distribution is the most real technology for existed ICT and infrastructures. From this viewpoint, in the paper up-to-date quantum key distribution protocols were carried out as well as analysis of their strengths and weaknesses, prospects and difficulties of implementation in ICT was fulfilled. Also the modern commercial quantum key distribution systems were analyzed in accordance to used protocols of key distribution and encryption.
