Evict+Skip: A High-Bandwidth, Non-Shared-Page Cache Covert Channel Attack

Streamline, a paper published in ASPLOS 2021, introduced an asynchronous framework to construct high-bandwidth covert-channels. However, it required that the sender and the receiver had to share the virtual memory, which made it less general. In order to figure this out, we proposed a brand new high-bandwidth covert-channel, which leveraged the directory conflicts of non-inclusive machine and the universal feature of Prime+Probe Attack.
