THE CONCEPT OF QUANTUM CRYPTOGRAPHY TO ENSURE SECURE DATA TRANSMISSION

The article is devoted to the study of quantum cryptography methods and their application in modern communication systems in order to ensure the security of secret data transmission. Such methods can include quantum key distribution, quantum cryptography on continuous variables, quantum networks, quantum digital signing and quantum secret sharing. The main protocols of these methods, the steps and results of their application, as well as advantages, such as the impossibility of interception of keys, detection of interception attempts, a large volume of transmitted information, a high level of security, the use of quantum phenomena, the impossibility of forgery, a guarantee of message integrity, multi-party security are considered. The study includes an analysis of quantum cryptography methods, as well as consideration of the possibilities of applying these methods to ensure the security of confidential information transmission.
