FIELD: protocols for interaction of peer entities of network structure and, in particular, concerns protective infrastructures for protocols of interaction of peer entities.
SUBSTANCE: methods are provided, which suppress capability of malicious node to disrupt normal operation of peer-to-peer network. Claimed methods allow nodes to use both protected and unprotected data about identity, ensuring self-check thereof. Then necessary or comfortable, association of ID is checked by "enclosing" a trustworthiness checking procedure into appropriate messages. Probability of connection to malicious node is initially reduced due to random selection of node with which connection is established. Also, information from malicious nodes is identified and may be discarded by recording information about previous connections, which will require a response in the future.
EFFECT: creation of protection infrastructure for a system with peer-to-peer network structure.
