FIELD: communication. SUBSTANCE: method for two-point communication involves receiving request with destination identification by first communication node from two-point communication operator; generation of individual call code variable in response to request by means of modification of encrypting key using given function; transmission of identification data of encrypting key and information about given function from first node to destination node, reception of identification data of encrypting key and information about given function by destination node, generation of individual call code variable by destination node. when individual call code variable is defined by both first communication node and by destination node, both communication nodes may engage in secure two-point communication. EFFECT: increased security of point-to-point communication. 5 cl, 2 dwg
