Compromising Emanations from USB 2 Interface
In the article assessment of the possibility of use and usability of USB 2.0 interface in IT devices used for classified information processing to minimize the risk of electromagnetic eavesdropping has been made.In those devices the aim is to minimize the level of radiated emissions via radio path,in which there is a high probability of interception by unauthorized persons and reproduction of conveyed information.The article has focused on revealing the possibility of eavesdropping of radiated compromising emanation during data transmission through USB 2.0 interface.For that purpose a comparative analysis of signal occurring directly on transmission line of USB 2.0 port has been made as well as its equivalent received by FSET 22 receiver as radiated emission.For the analysis signals generated by transmission lines of USB 2.0 port have been used.They were obtained as a result of measurements directly on transmission line and at the output of envelope detector of FSET 22 receiver received as radiated emission.
