Executive Summary

Heavyweight security analysis systems, such as taint analysis and dynamic type checking, are powerful technologies used to detect security vulnerabilities and software bugs. Traditional software implementations of these systems have high instrumentation overhead and suffer from significant performance impacts. To mitigate these slowdowns, a few hardware-assisted techniques have been recently proposed. However, these solutions incur a large memory overhead and require hardware platform support in the form of tagged memory systems and extended bus designs.
