Abstract: P2P (Point-To-Point) communication is an essential part of the decentralized networks. In general, those networks are public and not centrally managed. The paper focuses on reviewing possible places, where processing of the data happens – from the operating system processes, through transferring that data to a remote node (data in transit), to processing the data and finally storing/saving (data at rest) it. The article presents a new approach of securing the authentication and communication in P2P communication in decentralized networks – to store and keep the public keys for the SSH communication in a blockchain, instead of a local file (generally, different in each node). Possible application of this security improvement is in any decentralized network, where the nodes are known and trust each other. In such a blockchain, the number of blocks will be the exact number of participating nodes and each block will keep information for the keys (for example the public SSH Key(s)) of a si
