Capsicum: practical capabilities for UNIX
Capsicum - Related
The Computer Science Laboratory (CSL) at SRI International and the University of Cambridge Computer Laboratory have teamed on a successor project to Capsicum, CTSRD, looking at modifications to contemporary CPU designs in order to better support application compartmentalisation. The CHERI processor implements a hybrid capability structurally similar to Capsicum, only at an instruction set level.
A variety of research, commercial, and open source projects have explored the area of capability systems in the past. Here are a few of the notable ones we have referenced in our work:
