METHOD AND DEVICE MEANT FOR REALIZING PROTECTION CONTROL DURING ELECTRONIC MESSAGE EXCHANGE

摘要

FIELD: communications engineering, possible use for checking protection of message (Msg), which is transmitted and received in electronic form.;SUBSTANCE: in accordance to the invention method contains stages at transmitting side, at which unambiguous message identifier is associated with message (ID_Msg) and control identifier (ID_CONTR) of identification code of message owner, which is received by applying encoding (12), connected to owner of transmitted message, to unambiguous message identifier (ID_Msg). At receiving side method contains stages, at which fact of presence or absence of already received message with the same associated unambiguous message identifier (ID_Msg) is checked and transmitted by means of signal, and match is determined between unambiguous message identifier (ID_Msg), associated with received message, and result (ID_DCONTR) of decoding of user name of control (ID_CONTR).;EFFECT: ensured control of protection of message which is transmitted and received in electronic form.;3 cl, 3 dwg
