Abstract:

Trusted and untrusted networks in cloud environment are not allow to communicate with each other directly but they might share some common paths. These common paths give chances to attackers in untrusted networks to steal secrets from trusted networks by exploiting packet arrival intervals, so-called covert timing channels. We build a mathematical model for these channels to analyse their channel capacity. We demonstrate that these channels are very sensitive to the normal background traffic. We also develop an analysis to reason about the effectiveness of one of mitigation methods?randomly select paths for packet flows.
