| Abstract: | Covert channel is a hidden security trouble in a computer system . In RedHat Linux ,we find one sort of covert channel : Upgraded directory covert channel . We compute the bandwidth of this covert channel and test the bandwidth of the aggregation of this covert channel . The testing result shows that the aggregation of this covert channel will more heavily compromise the security of the system . We should pay more attention to the aggregation of covert channel . |
