The work aims to develop software for implementing secure corporate communication using peer-to-peer networks. The method of authenticating nodes in a hybrid peer-to-peer network has been improved, which, unlike the known ones, differs in the use of zero-knowledge proof for verifying the node by the server and another node, which provides protection of internal network resources from unauthorized access. A method of secure exchange of identification data between nodes has been proposed, which, unlike the known ones, consists of the combined use of NFC technology and zero-knowledge proof and provides protection against attacks with traffic interception. A method of secure exchange and storage of files has been improved, which, unlike the known ones, is based on the IPFS protocol using file encryption using pseudo-random byte permutation, which protects against violation of confidentiality and data availability. Software modules for a peer-to-peer network have been developed, based on the principles of clean architecture. The created software provides secure corporate communication, including file and message exchange, with guaranteed data confidentiality, access control, and user authentication. The scope of application of the work results is use in enterprises. Product Description popup.authors Azarov Oleksii D. Zakharchenko Serhii M. Krentsin Mykhailo D.
