Amplifying Main Memory-Based Timing Covert and Side Channels using Processing-in-Memory Operations

arXiv:2404.11284v1 Announce Type: new
Abstract: The adoption of processing-in-memory (PiM) architectures has been gaining momentum because they provide high performance and low energy consumption by alleviating the data movement bottleneck. Yet, the security of such architectures has not been thoroughly explored. The adoption of PiM solutions provides a new way to directly access main memory, which can be potentially exploited by malicious user applications. We show that this new way to access main memory opens opportunities for high-throughput timing attack …
