Selective Noise Based Power-Efficient and Effective Countermeasure against Thermal Covert Channel Attacks in Multi-Core Systems

With increasing interest in multi-core systems, such as any communication infra-structures can become targets for information leakages via covert channel communication. Covert attacks lead to leaking secret and data. To design countermeasures against these threats, we need have good knowledge about classes of along with their properties. Temperature–based channel, known Thermal Channel (TCC), pose a threat the security critical In this paper, present novel scheme TCC attacks. The adds selective noise thermal signal so that possible attack be wiped out. addition only happens at instances when there are chances correct exchange increase bit error rate (BER) keep power consumption low. Our experiments illustrated BER 94% while having similar state-of-the-art.
