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 ...
