FIELD: information technology.
SUBSTANCE: method involves the following: transmission of a detection secret from an initial domain to a correspondent domain, where the detection secret includes the initial domain address to which the correspondent domain sends the message so as to establish coordination between the initial domain and the correspondent domain, and reception of an invitation from the correspondent domain by the initial domain through the initial domain address, where in the initial domain, the data element received from the correspondent domain is verified by repeated calculation and subsequent comparison of the data element for the correspondent domain with the data element included in the detection secret sent to the correspondent domain, where the initial domain corresponds to the correspondent domain only when the data element provided by the correspondent domain coincides with the data element included in the detection secret, so that risk of a denial of service attack from the correspondent domain is low.
EFFECT: high fault-tolerance and counteracting unauthorised mailing a computer communication system.
