Arizona State University and Intel Corporation have teamed up to pioneer a groundbreaking framework called Controlled Shared Memory (COSM). As data communication becomes increasingly complex, especially with systems relying on standards like Compute Express Link (CXL), the need for stringent security measures is paramount. This new proposal aims to enhance security by dynamically controlling how data is shared via shared memory approaches.

Their research introduces the concept of COSM isolation, which offers a dual-layer approach to data security—firstly through a write-and-read permission matrix, and secondly via data inspection. This strategy goes beyond current isolation methods, such as virtual machine isolation or hardware-assisted solutions, offering potentially greater security measures.

By implementing host-to-host isolation on a Field Programmable Gate Array (FPGA), this framework evaluates data throughput and latency, illustrating its viability under various conditions. Consequently, COSM could very well lay the groundwork for a new realm in IT security, focused on shared memory communications.
