CAPIO: Safe Kernel-Bypass of Commodity Devices Using Capabilities
Securing low-latency I/O in commodity systems forces a fundamental trade-off: rely on the kernel's high overhead mediated interface, or bypass it entirely, exposing sensitive hardware resources to userspace and creating new vulnerabilities. This dilemma stems from a hardware granularity mismatch:...
Biting the CHERI Bullet: Blockers, Enablers and Security Implications of CHERI in Defence
There is growing interest in securing the hardware foundations software stacks build upon. However, before making any investment decision, software and hardware supply chain stakeholders require evidence from realistic, multiple long-term studies of adoption. We present results from a 12 month...

What’s the smallest variety of CHERI?
The Portmeirion project is a collaboration between Microsoft Research Cambridge, Microsoft Security Response Center, and Azure Silicon Engineering & Solutions. Over the past year, we have been exploring how to scale the key ideas from CHERI down to tiny cores on the scale of the cheapest...

Security Analysis of CHERI ISA
Is it possible to get to a state where memory safety issues would be deterministically mitigated? Our quest to mitigate memory corruption vulnerabilities led us to examine CHERI Capability Hardware Enhanced RISC Instructions, which provides memory protection features against many exploited...
