A fast and general software solution to mutual exclusion on uniprocessors... The idea is to execute atomic sequences without any hardware protection and, in the rare case that the atomic sequence is interrupted, to rollforward to the end of the sequence....
Optical encryption device for software protection... Software piracy and illegal usage require that software operation is secured through a form of hardware protection....
An analysis of the intel 80x86 security architecture and implementations... In this paper, we discuss the imbalance in scrutiny for hardware protection mechanisms relative to software, and why this imbalance is increasingly difficult to justify as hardware complexity increases....
The til/ml compiler: performance and safety through types... Unfortunately, both of these techniques exact a cost at run time: Hardware protection requires expensive context switches and data copying to communicate with the kernel or other processes, whereas SFI requires run-time checks for loads, stores...
