QUANTUM CRYPTO ENCLAVE FOR IMPLEMENTING UNCOMPROMISED TRUSTED DATA CENTERS

Purpose of the study: development and justification of the architecture of a quantum-cryptographic system for protecting access to a data center with high requirements for the confidentiality of processed information belonging to various entities, using federated learning problem as the example. Methods of research: systems analysis. Result(s): the problem of ensuring the confidentiality of data belonging to different subjects during their joint processing is considered. The concept of a cryptoenclave is studied as an effective approach to implementing the task. An analysis of modern and prospective threats to cryptographic methods of information protection is carried out. The concept of a quantum cryptoenclave is proposed, combining technologies of cryptographic information protection and quantum key distribution. An example of a possible implementation of a quantum cryptoenclave for solving the problem of federated learning is given. Scientific novelty: an architecture of a quantum cryptoenclave is proposed – a data center with cryptographic access protection using a quantum key distribution network with trusted intermediate nodes.
