FIELD: information technology.

SUBSTANCE: method provides forming of multiple trusted assemblies on rights of individual clients of communication operator, which is divided into r subsets, in the list of addresses the following data is registered: composition subsets for each of the corresponding pairs in the direction of transmission, a list of authorised IP addresses for each of the trusted nodes and subscribers of corresponding pairs. On the trusted units a traffic is generated, after extraction in the formed datagram of addresses of sender SA and recipient SB from a list of addresses one of number of authorised units allocated for this pair is selected, one of permitted IP addresses of sender and one of permitted IP address of the selected trusted node, the T number of intermediate trusted nodes is determining determined on a route of datagram transfer; IP address of the source and IP address of network datagram destination are selected as IP addresses of sender and the selected trusted node, the “option” field network datagram is populated with number of trusted intermediate nodes on a route of datagram transmission, after receiving a network datagram on a trusted node is checked the specified value T in the “option” field if T=0, then from a list of addresses one of the permitted IP addresses of the recipient and trusted node is selected, IP-address of the source and destination IP address are recorded into field “Source IP-address” and “Destination IP address” for network datagram; IP address selected for trusted node and recipient are transmitted over a communication channel as formed datagram.
