CoRR, 2019 Any secure network is only as secure as its weakest component. With overt channels tightly secured and attackers have started focusing on optical, audible, magnetic, and thermal covert channels to access sensitive systems. In this paper, we present a novel, reliable and bidirectional optical covert channel which uses optical mice.

IEEE Computer Architecture Letters, 2017 GPUs are increasingly used to accelerate the performance of not only graphics workloads, but also data intensive applications. In this paper, we explore the feasibility of covert channels in General Purpose Graphics Processing Units (GPGPUs). We consider the possibility of two colluding malicious applications using the GPGPU as a covert channel to ...

On the computation of covert channel capacity [PDF]
RAIRO - Theoretical Informatics and Applications, 2010 The paper deals with the bitrates (or capacity) of covert channels that is to say systems which allow unidirectional communication between a sender and a receiver. One first defines what is meant by covert channels, and then the basic properties of bitrates are displayed. Then one provides various techniques which can be used to obtain lower bounds for

MRCC: A Practical Covert Channel Over Monero With Provable Security
IEEE Access, 2021 Covert channels are designed to protect the communication relationship of the sender and receiver. Traditional covert channels have become insecure due to the continuous improvement of traffic analysis techniques. In this context, there is an urgent need
